How to breed urea for spraying trees in autumn. Copper vigorous to fight pests and diseases in spring

So that the trees did not hurt and gave good harvestIt is necessary every year in the spring to carry out prophylactic spraying. With the help of copper sulfate and urea can be created good solutionwhich protects the garden from various fungal and bacterial infections.

But what is a spraying of fruit trees in spring urea and copper vitriol? How to prepare therapeutic solution? And what precautions do you need to stick when spraying? Below we learn answers to these questions.

General information about copper vigor and urea

Let's first find out that it is a copper sulfice and urea:

1. Copper Kuner. Copper vitrios is called copper sulfate, each molecule of which attaches exactly 5 water molecules. This substance is used in gardening as a fungicide and antiseptics to combat fungi and bacteria that can cause various plant diseases. Copper vigoros is a substance of a contact type. In other words, this substance after applying to the plant does not penetrate the leaves and is not embedded in the metabolism. However, it is worth remembering that the copper cunery is considered toxic substanceSo, when spraying trees, you need to observe the dosage of the vapor, and the spraying should be carried out in special protective clothing.
2. Urea (carbamide). The urea is called a chemical compound, which consists of 1 carbon atom, 4 hydrogen atoms, 2 nitrogen atoms and 1 oxygen atom. Since the urea includes nitrogen, this connection can be used as a fertilizer for soil. After making urea to the soil, special soil bacteria decompose urea to ammonia and nitrates, and nitrates are already digested by plants as a valuable nitrogen source. The use of nitrogen fertilizers increases the yield sharply, however, when the dosage is exceeded, the excess number of nitrates can accumulate inside the plants - if a person is eating the fruit with large quantity nitrates, then the poisoning may occur. Therefore, when spraying, care must be taken, so as not to make plants to poisonous.

Spraying trees

Spring garden treatment with a solution of mud and urea is carried out in 3 stages. At first it is necessary to prepare trees and make a solution, and then you need to spray trees.

Preparation of trees under spraying looks like this:

1. Cut all patients and dry branches.
2. Turn the trunks.
3. Get rid of last year's foliage (if it is).
4. Speak the earth around the trees.
5. Clean the plots of dead crust.
6. If the tree in the winter slept the pests, then lubricate the damaged sections with garden water.

Now you can proceed to the preparation of urea and copper-based solution:

1. Dress the protective suit, gloves and glasses.
2. Take 50 g of copper sulfate and 600-700 g of urea.
3. Place these components in a dry enamel container. It is prohibited to use iron containers, since iron can enter into a chemical response with a vigorous.
4. Pour into the container of 9-10 liters of water and mix the solution thoroughly.
5. Straighten the solution.
6. Remember that the resulting solution must be used immediately after cooking, and it is necessary to store it for no more than 10 hours.

Now you can proceed to spraying:

1. Dress the protective suit, glasses and gloves (if you were filmed after the preparation of the solution).
2. Fill the sprayer with a solution.
3. Spend a spraying of trees.
4. Spraying need to be carried out into dry weak weather at temperatures above +5 degrees. Spray trees preferably in the morning or day.
5. Preventive spraying should be carried out until the kidneys is dissolved. The following preventive spraying is recommended after flowering.
6. Spring prophylactic spraying is aimed at protecting the garden from fungal infections, pasta, pathological spotting, putrefactive diseases, and so on. Also, this solution will help get rid of pests that live inside the tree (fruit mites, apple mole and so on).

Precautions

Let's learn the basic precautions that need to be remembered when treating a garden with a solution of urea and a mood:

1. In no case do not pour plants with plenty of solution. It is recommended to perform spraying selectively. Remember that a large amount of copper vapor and urea can poison the plant.
2. It is not recommended to process plants with a solution of mood and carbamide during the rain, as well as at a very high ambient temperature.
3. In no case do not repeatedly spray the wood with a solution of copper and mosquap after the rain. This can lead to copper accumulation in the soil, and the soil itself will become unsuitable for growing crops.
4. There is a solution poorly at plants, add several tablespoons of sugar or 20-30 g of soap into it.
5. When buying, pay attention to the integrity of the packaging and the date of manufacture.

Successful to the garden will help timely and proper treatment Plants and shrubs with special substances. One of them is urea. Spraying the garden at the beginning of the cold will help him to protect him for the entire winter, will save him from pests and diseases, increase the harvest several times.

What is urea, its features, how to use, prevention measures towards a person. All the aspects of gargrin are described in detail in next material. An important role is played by the garden processing time, stick useful recommendations Specialists, enjoy a big harvest.

Features urea

Carbamide or urea refers to granular fertilizers, it includes about 46% of nitrogen. The tool is considered the most concentrated nitric fertilizer for the garden, and is also used to process the garden. Some gardeners are often confused by the urea with Selutyrah, which is dangerous for the leaves of plants.

A carbamide is produced in the form of white crystals, yellowish shades that have no smell, without any problems dissolve in water. At a temperature of more than 80 degrees, the dissolution process occurs faster, the tool is perfectly distributed over all plants. Fertilizer itself absorbs moisture, therefore it is stored for a long time, for long storage, pack carbamide into containers.

Finding into the soil, the carbamide steps into the reaction with bacteria, microorganisms that are in the ground. The first three days lasts chemical reactionwhich contributes to the conversion of urea into ammonium carbonate. In contact with air, the substance is transformed into ammonia gaseous.

It is due to this feature, urea need to be chopped into the soil, the absence of this process will lead to the loss of most useful properties. Therefore, the granules that scatter around the trees are necessarily sealed (for eight centimeters) to achieve the goal.

When working with carbamide, consider such aspects:

• the substance acts immediately, its positive effect is maintained for a long period of time;
• carbamide refer to K. organic compoundsbut experts relate to nitrogen-containing fertilizers;
• urea must be made directly into the soil, the substance has a property quickly dislike;
• the substance can be used in any soil, even in greenhouses and greenhouses;
• urea shows excellent results on well-moistage soil;
• in the soil, which has high biological activity, the carbamide loses less nitrogen than in the soil, which is neutral, alkaline;
• urbamide is considered the safest nitrogen-containing fertilizer, which summer period (even when the dosage is exceeded, the leaves do not burn);
• the treatment of the urea garden is useful not only in autumn (in order to protect against frost, pests), but also in the spring (when the kidneys are formed, the substance destroys all pests and diseases);
• also in spring period The substance can slow down the growing season, the kidneys ripen later, which protects plants from spring frosts;
• with the help of urea, it is impossible to get rid of the stumps, their processing will only accelerate the process of rotting;
• it is strictly forbidden to mix carbamide with other fertilizers (chalk, lime and others).

Advantages and disadvantages

Urea possesses weight positive qualities In relation to plants in the garden. The substance is of great popularity among gardeners, helps to destroy pests, improve the quality of the harvest.

The pluses of the substance include:

• urea solution is quickly absorbed by various cultures, especially sensitive to high pH indicators in the ground;
• urea helps to overcome many pests in the garden, copes with a variety of diseases;
• extra-corner feeding of the plant does not cause burns;
• regular feeding of urea plant in the garden contributes to an increase in the crop.

Any product has its drawbacks, urea is no exception:

• rehend to fertilizer carefully, improper storage causes substance;
• urea can not be mixed with other fertilizers;
• upon exceeding the concentration of carbamide in the soil, the germination of seeds is reduced.

For getting desired result Follow the Garden Processing Rules in the fall, properly prepare the solution, follow the safety technique.

Preparation of the garden to carbamide processing

In front of winter, insects are looking for cozy places for shelter from frost. These places it is customary to consider the foliage, the bark of trees. That is why the garden spraying is carried out late in autumn. Such manipulations will remove trees from the invasion of the paste, putrefactive diseases, other misstain. As a result of the processing of the garden, the vegetative process is accelerated, the reproduction of pathogenic microorganisms is terminated or significantly slows down.

To obtain the desired result, it is necessary to properly prepare plants. The process is carried out in several stages, the age of plantations is taken into account:

Many gardeners prefer to process the garden in late autumn (from the beginning of October until the end of the month). Before the colder to carry out the procedure most favorably for plants. If you hold a procedure early autumn (in September) detrimental for plants. They will remain without vitamins and minerals, can get burges, early reset the foliage. The depressing state of the garden will contribute to the attack of pests in the spring, well, if the plant survives.

For sick plants, carry out unscheduled manipulations. Also after treating urea many gardeners whites trees. The combination of beneficial manipulations shows excellent results.

Important! It is extremely undesirable to carry out the garden processing in front of the rain. Shone simply will destroy fertilizer, it will not be reduced to your works, the plants will remain not protected. Cut the manipulation into a sunny, windless day.

Security measures

Treatment of trees and bushes in the garden is a useful and necessary business. The procedure passes using a special pulverizer that sprays suitable substance. Do not forget about the safety technique, which will save you from the negative impact of chemicals on the body. Negligence with pesticides leads to serious problems with health.

In stocks of any gardener should be:

• respirator;
• protective special suit;
• gloves.

Wear the entire protective kit before starting work not only in the fall, but also in the spring.

What if you appear and how to stop the reproduction of harmful insects? We have an answer!

How to process the garden

Stems should be treated, branches, land around trees. Such manipulations are excellent protection against pests, diseases. Excess dosage funds are not recommended, If the leaves do not fall, then the likelihood of early falling foliage increases, reducing the frost resistance of trees in the garden.

You need to handle not only trees. The garden is filled with both bushes, their spraying is carried out in several other way:

• active processing is shown in the case of nitrogenous fasting (the plant is significantly lagging behind in growth, the bloom is very weak, there are no scrolls, the leaves are twisted into the tube, yellow, all the fruits quickly appear, are formed in small quantities);
• for work, you choose earlier morning or late evening;
• for spraying shrubs, a solution is used: ten liters of water, 40 grams of urea.

It is possible to use the carbamide not only in the form of a solution, the substance is scattered over the ground, is covered with soil to avoid weathering. Each plant requires special proportions with a supersonic bait:

• 8 grams per square meter are used for cucumbers;
• cabbage, onions, tomatoes of any variety, potatoes, pepper sweet are treated with this solution: twenty-five grams per square meter;
• the bait of strawberries, blackberries, cucumber or tomato is carried out with the help of a solution in a proportion of ten liters of water: 25 grams of urea;
• eggplants and patissons require 10 grams of carbamide per square meter.

To date, the carbamide is considered the most popular nitrogen-containing agent. Fertilizer is considered one of the safest and more efficient, it is used not only in the autumn period, but also in the spring. The cost is somewhat higher than other similar means, because urea is obtained by artificially (ammonia synthesis and carbon dioxide). The cost of the substance justifies a rather big value due to high efficiency, Safety for plants.

Preface

Which of us wants to eat fruit in your diet, if you know that the trees on which they grew were processed by a large number of chemistry? That's right, no one. What to do to get a healthy harvest and what drugs to handle the garden are needed - read in our article!

Required tools and materials

Preparations for garden processing - Help yourself

For most citizens, the issue of using drugs used to handle the garden is sufficiently important, because no one wants the chemistry to remain in the fruits and then fall into the body. Yes, and everyone understands that poisoning themselves harmful substances dangerous. In the meantime, experts in the industry agrochemistry assure that these drugs are most effective in combating diseases and all sorts of midges. The calendar of the garden treatment calendar from pests has a rather tightly scored schedule. So, spraying is carried out in four stages: the first - before flowering, the second after, the third is only 10 days after the second spraying and the fourth - in 10-12 days after the previous one.
But, having your own garden, we can calmly control the dose of the drug used on their dose area. After all, each of us can stop and not use without a particular need for a substance, applying reasonable doses in combating or, for example, apple trees.

So, there are several drugs most frequently used when processing the garden - this is urea (carbamide) and copper sulphate. At least one of them heard each, even having no relation to the garden and the garden. The main advice of specialists are as follows - if you have a healthy garden, it should not be treated with such a number of drugs. It is not necessary to spray even in the event that in the trees the concentration of pests is too small. It is permissible. Processing problem areas can be selected. It is also important to conduct, if we have been gathered, treated trees on time and most importantly, correctly dissolve drugs before using them. If you still decided to splash, then ask what drugs are affected by what processes. The same policy should be adhere to both the bazaar, where buying fruit from the hands, you can ask the garden host about the class of chemistry in the cultivation. Another thing is that no one guarantees you the truthfulness of the answer.

In our case, the number of treatments is important. After all, it is certainly, many have noticed that apples in supermarkets can be on the shelves for several weeks and do not spill at all. Most likely, in this case, this product was processed not once to achieve such a result. So, if a tasty and juicy fruit is bought by you not at all in the maturation season, this is not a reason to enjoy the vitamins obtained by your body. Although, of course, quality control exists in the food procurement and sales system, but it is better to progress yourself and not to risk similar purchases.

Garden treatment with copper vitriol - what, why and why

Each dacket wants to get a good harvest, but sometimes without the use of the same copper mood of the desired simplicity, do not wait. The pests, along with plant diseases, and not always favorable weather, lead to the fact that both bushes, and trees begin to die on the site. Specialists advise in the event that such a situation it makes up annually, to apply against pests and diseases chemicals - Fungicides. They help warn the most common bacterial and fungal diseasesAnd besides this and cure already sick plants.

So, a solution of copper mood, the fortress of which is 2%, it is better to use early and late spring When spraying. Helps against fruit rot and a number of other diseases. When preparing a solution, it is necessary to take into account that it is mixed only in the wooden or permissible in the enameled dishes. First, the chip crystals are poured hot waterSo that they are better dissolved, and then plot some more and cold water. If you use copper sipop in pure form, it will simply burn their plants, so it is possible to use such a solution only in the mixture in a ratio of 1: 2 with greased lime or soda.

A familiar "burglar liquid" is a mixture of copper vapor and lime milk. This solution is successfully used against many fungal diseases, it does not help the truth to recover from muced dew. Liquid can be prepared by itself - for this wooden dishes pour a little hot water and dissolve 1 kg of copper sulfate in it. Next you should add 50 liters cold water. In another dish, 1 kg of lime is quenched. Then add 50 liters of water and filtered. Before spraying, a solution of a sulfate is slowly pouring into lime milk. And then you can apply on plants.

Specialists advise carefully to carry out similar processes and mix the compositions only in the specified sequence.

In addition, in no case can you dilute the burglar liquid after it is prepared by water. And yet, it is necessary to use a solution only in warm and dry weather, since there may be burns on the leaves and fruits with a strong heat, and the rain just reduce all your efforts.

Treatment of garden carbamide - increases the crop and fights pests

With the invasion of pest insects on the trees, carbamide is coping with the trees. Carbamide can be used both fertilizer, and as a means of combating different pests. So carbamide (urea) is used for processing after the arrival of heat, if the average daily temperature plus 5 degrees and higher, the kidneys began to grow. In this case, the struggle against pests is carried out at the wintering stage. Trees are sprayed with concentrated urea solution, 500-700 grams per 10 liters of water. Such processing should be carried out if there was a pest invasion last season.

Such a solution helps and with such diseases as purple spottedness or a pass. Spraying the garden of the urea can be carried out in the fall. Spray the leaves of trees, which helps to reduce the ability of the subsequent infection of the apple tree. Replace urea (carbamide) can ammonium nithe or potassium chloride. I only process with the soil, but not a bark and kidney.
In addition, the carbamide has long been common not only in large farms, but also on dumart sites as an effective nitrogen fertilizer. It accelerates the growth of the plant. In addition, it is loved to use it for ease of use, fast solubility and extraordinary ease of assimilation by plants. This is the most concentrated nitrogen fertilizer that can be used as on panstonesand in large farms. Dissolving well in water, suitable for all types of soils as fertilizer and feeding. Does not harm the leaves and leaves no burns on plants. Recall that the selection of dosages should always occur taking into account the characteristics of the fertile layer, such as the soil

Tips when treating garden drugs:

The use of urea on the garden as a fertilizer is in demand if necessary, improving the soil characteristics of any type of soil, as well as a feeding of garden trees, berry plantations or garden plants. To obtain maximum effect Must be sure to follow the instructions, both in terms of time and at the dose of carbamide.

Carbamide: appearance and chemical composition

Carbamide or urea is chemical compound, the final product of protein metabolism and the most concentrated of all nitrogen fertilizers known to date. Release form - granulated, which provides fertilizer excellent physical characteristicsand also prevents mela and allows urea to save good indicators dispersibility.

This fertilizer option is used to feed any agricultural and garden crops in the form of a solution, which is also in demand as root and extraxanlety feeding. The carbamide is actively used as a component in the production of complex composition of fertilizers, and also enters many slowly acting nitrogen-containing fertilizers.

In pure form urea is a colorless crystalline substance, not smell and possessing the following characteristics:

• solubility indicators B. aquatic environment depends on temperature mode liquids and can vary in the range of 50-95 g;
• substance is soluble in media such as methanol, ethanol, isopropanol and others;
• it is characterized by the ability to form compounds with the inclusion of inorries and organic substances.

Colorless fertilizer granules represented by urea, have dimensions in the range of 1-4 mm, and mass fraction Nitrogen is 46.2%.

Carbamide properties (video)

Instructions for the use of urea in the garden as a fertilizer

Very well soluble in aquatic environment CarbamideWhen entering into the ground has the effect of weak soil acidification, therefore, if necessary, lime is performed.

Making urea to the soil must be carried out in advance, in the early spring period or under the execution of autumn plowing. It is allowed to use amide substances in the form aqueous solutions When irrigated, or in the process of direct mixing with the soil when loosening.

Extra-corner feeders of garden plants are shown by any vegetable crops with pronounced nitrogen starvation, as well as if there is a mass crease of the barriers. In this case spraying green mass properly cooked urea solution especially efficiently And gives the most quick positive results. For the preparation of such a solution for extractive food of plants, it is necessary to dissolve 5-10 g in a liter of water room temperature. There is such an increase in the treatment of 20 sq. M. Grocery. It is necessary to produce such an event only in the morning hours or evening, after sunset.

Features and options for using a carbamide in the garden

When using urea, it should be remembered that the introduction as granulated fertilizer It assumes a shallow dressing in the ground, which will prevent the flushing of carbamide from the soil during the rain or irrigation.

It is important to note that such a way of protection is categorically prohibited for use on vegetable cultures, and the neglect of the rule becomes the cause of the death of the above-ground part of the garden plants.

For processing the crown of fruit plantings, it is recommended to use a solution based on a bucket warm waterwhere you need to dissolve 0.5 kg of fertilizer. Thirt of the agent can be processed about ten square meters Garden plantings and berry shrubs. Spraying trees and bushes are carried out in the fall, Immediately after leaffall. As a rule, it is enough to perform only one processing to get rid of insects and pathogenic microflora.

Carbamide for trees: spraying (video)

How and when to feed trees and shrubs urea

If plants need not only effective protection, but also high-quality feeding, then fertilizers are entered into a rolling circle in compliance with the following norms:

• young apple trees and pears - 0.15 kg;
• fruit apple trees and pears - 0.25 kg;
• young cherries and plums, as well as other bone cultures - 75 g;
• fruit cherries and plums, as well as other bone crops - 0.12-0.14 kg;
• berry cultures - 75 g

Superficial feeding title Circle It is performed by splashing the solution, after which the soil processing is performed by robbles. The most effectively carry out such an event in the spring period, as well as at the stage of active fruction of garden plantings and berry shrubs.

The advantages and disadvantages of the carbamide as feeding

Urea or carbamide used as feeding, has a significant number of positive properties, among which are the most important following:

• urea-based solution is quickly and efficiently absorbed by any cultures that have increased sensitivity to high pH indicators;
• properly performed extra-green subcords They are not able to cause burns on the leaf plates in plants;
• in a timely manner, under compliance with the norms of subcording, the carbamide can significantly increase the yield of not only fruit-berry, but also garden, vegetable plants.

Urea is not devoid of some disadvantages that need to be taken into account the process of feeding fruit-berry, vegetable and green crops:

• increased concentration of carbamide in the soil very often becomes the main reason for the decline in the germination of seed;
• when storing fertilizer, certain rules are required, which allow to maintain the activity of the active substance;
• urea should not be mixed with other compositions used for feeding gardening crops.

The principle of action of the active component is very simple. When inserted into the ground, the reaction occurs by sphere in components and earthy bacteria.

During the first pair of days there is a rather stormy chemical reaction that converts depositted urea into ammonium carbon dioxide. Contact with air causes transforming in ammonia of a gaseous state. It is for this reason that it is necessary to thoroughly close the implanted substance in the upper soil layers. It should be remembered That when using such compositions on soils with a strong or simply neutral reaction, significant losses and a decrease in overall efficacy are very often noted.

Garden fertilizers: varieties (video)

Carbamide is currently considered one of best forms nitrogen fertilizers suitable for both extractive and root feeding of any garden plants and fruit-berry crops. Properly divorced and introduced in accordance with the instructions of the composition do not block the foliage of garden crops and are able to be absorbed in the form of a whole, not decomposed molecule, which is positively affected on high-quality and quantitative characteristics of the crop. When used on the lungs in the composition of ferrous-podzolic soils with sufficient moisture and good irrigation, the use of urea is more efficient than the introduction of ammonia nitrate.

So that your garden looks well maintained, beautiful shrubs, fruit trees They were healthy and in the summer gave a good harvest, it must be properly prepared for the season. One of such important events, in addition to whitewashing and trimming trees is their spraying, and the most effective means for this is the carbamide (urea). Treatment of trees with urea spring decides several problems at once.

Characteristics of urea

Urea refers to K. nitrogen fertilizers The highest concentration is almost 46%. Some novice gardeners confuse her with Selutyra, which can be dangerous for foliage trees. A carbamide is produced in the form of granular crystals of white and yellowish shades, absolutely not having nasty smell, without problems dissolves in water (in hot to + 80 ° C, the process is faster) and is excellent on the processed areas. Due to their hygroscopicity, it must be stored in hermetic containers. Gardeners appreciate the urea not only for the large content of nitrogen in it, but also for high digestibility by plants. This is especially effective when dealing with harmful insects, when the road every minute.

Urea, when introduced into the soil, dissolves and turns into ammonium carbon dioxide, which is a unstable compound, decomposed in air to ammonium bicarbonate and ammonia. The formming ammonium is gradually absorbed by garden and suriable cropsAfter which there are no acid or alkaline residues.

For what you need to spray trees and shrubs in the spring

The beginning of the season, that is, the period when garden trees And shrubs, waking up after winter cold, begin to accumulate forces to form a fruit mass, is exactly the time when you need to take care of their protection. That is why the treatment of trees in spring from pests and diseases - an important stage In garden agrotechnology. In fact, spring is a cunning period. On the one hand, the tree needs time to recover after a long stay in extreme conditions of harsh frost, on the other - various pests, just after waking up from the winter hibernation, they begin to eat actively, with pleasure, poking on barely blooming leaves and flowers. It is not surprising that the care of trees in the spring includes mandatory treatment of pests, because if you cannot intervene in the process, the crop can not wait. Of course, it will not be possible to destroy all harmful insects in the garden, although this task is not put. Much more important to dump non-crude guests From the garden, make your trees and shrubs as unattractive as possible for such pests, both from the point of view of nutrition and in terms of "living."

Another important argument in favor of the spring processing of the garden from pests and diseases is that this period eliminates direct impact Yadohimikatov on the wound and fruit (simply because they have not yet formed), therefore, the fight against the pests of the garden is in the spring minimizes the risk of subsequent poisoning with such drugs as a result of eating treated fruits and berries. Thus, the main task of spraying the garden in the spring is to prevent pests and diseases that will tester your site throughout the season, including when the use of fungicides and insecticides will negatively affect the environmental purity of the crop.

Dates of garden treatment in spring urea

Processing fruit trees in the early annex period is much easier than after color. In the May Days, a pollinated urea will not be able to get to the upper branches of plants because of the thick young foliage and will not destroy the foci of infection on the top of the trees. The result will not be visible. If the garden, in general, consists of trees, giving urea to get through the young foliage (for example, pears and plums), then the subsequent, and even summer treatments will also be very effective.

An early spraying of the garden of the urea is also aimed at combating strong spring frosts. The nitrogen contained in the urea will slow down the exchange processes of the tree for a couple of weeks and will not allow young foliage and gentle inflorescences to bloom ahead of time. Thus, frosts that can cause irreparable harm fruit trees, Will passed. This property for gardens consisting of early varieties of trees such as peach, plum or apricot is especially useful.

Preparation of the garden to the processing of urea

During the spring blossom of the apple tree, plums and pears of the plant, it is recommended to treat urea. Such an event is very effective in order to prevent the lesion of the garden plantings of the caterpillars of the leaflerting, aphid, a mixture and apple color. Before processing, plants should competently prepare.

Immediately before processing, it is necessary to conduct sanitary trimming and remove all patients or affected sections of the cortex by reading them with a blade or metal brush. Such preliminary preparation Will be able to provide direct contact of the solution with an affected area or by the accumulation of insect pests in the process of spraying.

How to prepare a mixture of urea for garden processing in spring

The urea and copper sulfate solution for treating trees is prepared as follows:

• 700 grams of urea are poured into a clean 10-liter bucket;
• in the bucket poured water and stir until complete dissolution;
• in a separate dish, 50 grams of copper mood in a small amount of hot water are breed;
• the divorced vitriol is poured into a bucket and stirred again.

Spray trees in spring urea and copper vitrios need plentifully, missing trunk, branches and earth of the rolling circle.

Spring Urea Garden Treatment with Copper Campaign - This is a guarantee that your garden will be much healthier and please friendly harvest. But we should not forget that in order to obtain a good result in the garden, a whole range of measures. IN different fertilizers And the protection against diseases and pests trees need throughout the year.

Carbamide Now one of the most popular fertilizers, its share accounts for about 35% of all nitrogen subcorts. Although the urea is characterized by a higher price (due to its synthetic nature), it is safe for plants and acts on them quite effectively.
