What Fertilizer Does Urea Belong to

Urea, also called carboxamide, is a neutral and quick-acting fertilizer. It is an organic compound composed of carbon, nitrogen, oxygen and hydrogen, and it is also a nitrogen fertilizer with high nitrogen content at present. It is suitable for all kinds of soils and plants and can be used as base fertilizer or topdressing. After application, there will be no harmful substances left in the soil, which is easy to store, and it is not suitable for excessive or concentrated use, nor can it be mixed with alkaline fertilizers.

Precautions for application:

1. Urea is suitable for most crops and soils, can be used as base fertilizer and topdressing, and can also be applied in dry paddy fields.

2. In alkaline soil, urea should be covered with deep application, and it is not suitable for surface application, which will easily lead to ammonium volatilization and loss.

3. If nitrogen fertilizer is spread on the surface of paddy field, the ammonia volatilization loss will reach about 10-30%, for example, in alkaline soil, the ammonia volatilization amount will reach about 12-60%.

4. Urea should not be applied excessively or too intensively. When its concentration is 0.05%, it will inhibit the young roots and buds of crops to some extent.

5. Generally, urea can't be directly absorbed and utilized by crops, but needs to be converted into ammonium nitrogen. Under the action of alkalinity, a large amount of nitrogen in ammonium nitrogen will be volatilized, so urea should not be mixed with alkaline fertilizers such as calcium magnesium phosphate fertilizer, plant ash and ammonium bicarbonate.

Can vegetable seedlings be sown with urea?

The answer is yes. But we need to pay attention to the method of fertilization.

The newly sprouted vegetable seedlings can be applied with urea and fertilizer. However, it is necessary to use water to open the fertilizer, and the dosage should be small to avoid burning seedlings. Pay attention to the following ways to fertilize small vegetable seedlings:

The fertilization method should be scientific and reasonable, and the base fertilizer should be applied one week before the vegetable planting, and should be evenly mixed with the soil. Topdressing can be applied in ditches or holes 7-10 cm away from plants. After topdressing, soil should be covered and watered in time. Never sprinkle fertilizer directly on the ground or plants to avoid volatilization of fertilizer or burning vegetable seedlings. Topdressing outside the roots should be carried out in the peak period when vegetables need fertilizer and in the later period of vegetable growth, and it is best to choose it on cloudy days or in the evening, and try to spray fertilizer solution on new leaves and the back of leaves to facilitate vegetable absorption.

Try to apply special fertilizer for vegetables. On the premise of implementing formula fertilization, promote special compound fertilizer for vegetables. Special fertilizer is developed and determined according to the fertilizer demand characteristics of different vegetables and the fertilizer supply status of soil. It has more complete nutrients, more scientific nutrition, more reasonable formula and stronger pertinence, and can significantly improve the yield and quality of vegetables after application.
