Urea can be called one of the most popular fertilizers among gardeners and gardeners. It belongs to the number of nitrogen. It is usually produced in the form of white or transparent granules or slowly soluble tablets.
The use of urea for feeding vegetable crops
Urea fertilizer, the use of which is justified to support plants during flowering and fruiting, is applied mainly in a superficial way. Having scattered the required amount over the bed, the granules are lightly sprinkled with earth or covered with rakes in the soil. The fact is that if you leave them outdoors, some of the nitrogen may be lost. After this, the bed needs to be watered.
Once in the soil, urea as a fertilizer begins to interact with enzymes produced by the bacteria that live in it. As a result, part of it is converted to ammonia. That is why a little deeper into the ground granules will not hurt. Otherwise, the gas will simply evaporate. Deepening is also advisable when the site is very wet. If the granules are scattered on top, they can simply be washed along with rainwater.
Urea fertilizer, the use of which must be strictly dosed, can be used to feed almost all vegetable crops. In the case of tomatoes, potatoes, eggplant, onions, 20-30 g of granules are scattered per square meter. Eight to ten are enough for cucumbers and zucchini. In addition to granules, slow-dissolving tablets can be used. Once in the soil, they begin to gradually diverge, and this process lasts long enough. As a result, the duration of the fertilizer increases. The first top dressing is carried out after the appearance of the first flowers on the plants. The second - during the fruiting period, in order to support the plants.
Urea: use for fruit plants
For fruit crops, urea can be used both as a fertilizer and as an agent against pests. In the latter quality, it is not used for vegetable crops , since leaves can be burned.
Fruit trees are treated with a solution consisting of 500 g of urea and 10 liters of water in the fall, after foliage flies around. This composition is designed for 10 m2. They sprayed the branches of the crown of those trees where in the summer there were many pests.
For feeding, a tablespoon of urea is used per bucket of water - per one square meter of area. Urea fertilizer, the use of which in this case can also be carried out by a dry surface method, in this case is scattered around the near-stem circle and sealed with a rake in the soil. This is best done in the spring. In addition, top dressing should be carried out during the fruiting period and after shedding the first fruits
Some tips
When mixing urea with superphosphate, fertilizer must be used immediately. You cannot store it for too long. The fact is that urea over time begins to draw water from superphosphate, which leads to its clumping.
Urea fertilizer, the use of which is justified for both vegetable and fruit crops, is considered one of the most effective ways to increase their productivity. Of course, this is only possible with proper use. The advantages of urea include low cost.
