Treatment of the garden urea. How to process the garden urea

In order for your garden to look well-keeped, shrubs are beautiful, fruit trees were healthy and in the summer gave a good harvest, it must be preparing properly for the season. One of these important events, in addition to whitewashing and trimming trees is their spraying, and the most effective means for this is considered a carbamide (urea). Treatment of urea trees decides several problems at once.

Characteristics of urea

The urea refers to nitrogen fertilizers of the highest concentration - almost 46%. Some beginner gardeners confuse it with Selutyra, which can be dangerous for the foliage of trees. A carbamide is produced in the form of granular crystals of white and yellowish shades, absolutely not having an unpleasant odor, is dissolved without problems in water (in hot to + 80 ° C, the process is faster) and is perfectly distributed 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 the high velocity rate by plants. This is especially effective when dealing with harmful insects, when the road is every minute.

When working with urea, consider the following:

The carbamide refers to organic compounds, but is considered to be a mineral nitrogen-containing fertilizer.
The effect of urea begins immediately and has a long period.
Urea for the garden as a fertilizer is brought directly into the ground, since it has properties to disperse.
It is used in any soil, including in conditions of protection (in greenhouses and greenhouses).
Shows good efficiency on replete soils.
In soils having high biological activity, the carbamide loses less nitrogen, which cannot be said about alkaline and neutral soils.
Finding into the ground, urea is converted to carbon dioxide ammonium (ammonium carbonate).
It is the most efficient and safe nitrogen fertilizer for garden plants in the summer - does not burn foliage even with incorrect dosage.
Another of the very beneficial properties of urea is that it slows down the growing season - the flowering of trees begins later, and this helps to avoid the death of barriers from spring frosts. This is especially effective for the early grades of peach, plums, apricots.
In the period when kidneys are formed on trees, urea treatment solves the problem with many pests and various diseases.
Spring processing of the garden of urea helps protect the trees from frost.
The urea is useless when dealing with old stumps, it is not capable of destroying them completely, but only contributes to rotting.
In no case do not mix the carbamide with other fertilizers and minerals - chalk, simple superphosphates, lime.

Garden Preparation for Processing

Before starting the garden spraying in spring urea, it is necessary to take into account some recommendations:

The first spraying can be carried out at an air temperature of at least + 5 ° C.
Before processing, everything frostbed and dead sprigs are removed.
Spraying the urea garden must be carried out after pumping and loosening the soil.
Check if the trunks of the trees are not damaged and, if necessary, clean the trees with a metal brush from the dead crust.
Make sure that there are no harmful insects in the cracks of the cortex, which will be necessary to destroy.
Remove the whole that fell and not rotting the foliage from under the trees. First, it will interfere with the introduction of urea into the soil, and secondly, may contain the larvae of various parasites.

Fighting pests

The garden treatment in spring from diseases and impertors of urea is carried out as follows:

The first spraying is carried out even before the renal formation begins at air temperature from + 5 ° C. Parasites during this period are still inactive and are in the stages of hibernation. Garden processing is effective in the fight against tool, medaler, weevils, apple-eye bloom. The solution is prepared in the ratio of 500-700 g of urea by 10 liters of water. Especially recommended prevention in the event that last season was marked by the great activity of pests. By 10 square meters. The site is approximately 2.5 liters of the finished solution.
The urea is effective in combating dangerous diseases of diseases, such as monilial burn, purple spottedness and a passage. In this case, a solution is prepared in a ratio of 500 g per 10 liters of water. Finding on the foliage, urea acts in the infection on the causative agent, which loses the ability to reproduce. You can also process the fallen foliage in which the pathogens are inhabited, and the winter and winter.

Processing of fruit trees

Determine the time for treating fruit trees is very simple. As soon as ants appear in the trees, ants appear, in the near future you can wait for the invasion of Tly and other pests. For a very short time, these parasites can leave your garden without harvest. It's time to proceed to the work:

Urea garden treatment can be started if you were correctly prepared for this trees - they dreamed of land under them, removed frnit and damaged branches, twisted trees trunks.
For work is suitable solar and, which is especially important, a windless day. If the weather is hot, it is advisable to spend the spraying in the early morning or in the evening after sunset.
Prepare solution and spraying itself is necessary in protective clothing, mask, glasses and gloves.
Especially effective in the fight against insects urea will be in conjunction with copper vigorous - 700 g of carbamide, 50 g of copper mood and 10 liters of water. Such a composition decides at once two problems - destroys the pests and fertures the soil.
For spraying, it is best to use a special sprayer. With it, you can process even very high trees.
Processing trees, do not regret the solution, it is impossible to harm.
The second processing of the garden can be spent during the flowering of trees, and the third immediately after the tie of flowers.
If there is precipitation after spraying, it will be necessary to repeat the procedure, otherwise everything will be in vain.
The root feeding of fruit trees during the fruiting period is carried out in the ratio: cherry and drain trees will need from 120 to 150 g on 10 liters of water; Apple trees will require 230-250 g per 10 liters of water.
You can not prepare the solution, but to pour urea in dry form, but in this case you need to thoroughly pour trees with water.
In case of feeding the trees by organica, the urea application rate must be reduced by 1/3 or half, it depends on the amount of organic feeding.

Processing of other plants and shrubs

Surely, many gardeners in the garden are growing not only fruit trees, but also other plants, shrubs like fruit and decorative. They are also treated and fed by carbamide, which is also used as a fertilizer, and as a means of combating diseases and pests.

Recommendations for the use of carbamide:

The active feeding of plants is carried out in the case of nitrogenous starvation, which is manifested as follows:
- the plant begins to lag in growth;
- the leaves are yellow and twisted into the tube;
- bloom is weak, without barring;
- fruits and berries appear in small quantities and quickly appear.
For work, preferably morning or evening day. During the period of precipitation, the work is not carried out.
For the preparation of the solution, 30-40 g of urea on 10 liters of water is necessary.

Roots for root feeding:

for cabbage and onions of any variety, beets, tomatoes, sweet and potatoes pepper take 20-25 g per square. m.;
under beans and cucumbers - 5-8 g per sq..;
for feeding strawberries, blackberries, strawberries and vegetables such as cabbage, cucumber or tomato - 20-30 g per 10 liters of water. Under each bush or plant, it is necessary for 1 liters of solution;
the gooseberry is fed in the ratio of 10 g per 10 liters of water;
on currant take 20 g per 10 liters of water;
patchsons, eggplants and zucchini require 10-12 g per square meter.

To date, urea is the most popular tool to feed trees, shrubs and other plants - approximately 35% of all nitrogen-containing fertilizers. It can be bolded by one of the effective and safe, which confirms the high and ever-growing demand. The cost of the carbamide is slightly higher than that of other nitrogen-containing fertilizers due to the fact that it is not natural, but is obtained as a result of synthesizing from ammonia and carbon dioxide. But in this case you can safely say - the price justifies quality.
