Urea (carbamide) is one of the most concentrated nitrogen fertilizers.
It contains 46% nitrogen. The substance is odorless and dissolves well in water. Most often, gardeners use this fertilizer in the spring, when plants need nitrogen the most.
Urea stimulates the development of the vegetative part of plants. This is good at the initial stage, when the plantings awaken after winter. But during the period of bud formation, it is important not to overdo it with urea, otherwise this can lead to a drop in yield.
There are several nuances regarding the use of urea in the fall. During this period, microorganisms living in the soil decompose, so the released ammonium quickly breaks down.
In autumn, this fertilizer is used by those with sandy and sandy loam soil. But only if the weather outside is warm and rainless. However, autumn feeding is not suitable for winter crops and perennials.
In spring, urea is incorporated directly into the soil. Holes or furrows are prepared and fertilizer is poured into them. However, after this, the urea is sprinkled with a layer of soil. This is done so that the seed does not directly contact the fertilizer.
It is better to apply urea 1-2 weeks before sowing or planting. During this period, a chemical reaction of gaseous ammonia will occur, from which it is also desirable to protect the planting material.
