When feeding crops with urea, you need to remember that this fertilizer stimulates the development of the vegetative part, so applying it during the laying of buds can lead to a decrease in yield. It is best to make urea under the plants at the time of formation of the green mass.The introduction of urea in the autumn does not always give the proper effect, since microorganisms at this point begin to decompose, and the released ammonium is rapidly destroyed. In addition, by spring, part of the nitrogen sinks into the deeper layers of the soil, from where the plants can no longer consume it. The use of urea in the fall is justified only if the soil on the site is sandy or sandy, and the weather is not too warm and dry. Autumn feeding with urea is contraindicated in winter and perennials.Urea can also be applied to the soil before planting or sowing plants directly into grooves and holes. In this case, it is important to sprinkle fertilizer with a small layer of earth to avoid contact of urea with planting and seed material.In addition, in order not to expose the planting material to the action of gaseous ammonia released as a result of a chemical reaction, urea can be introduced 1-2 weeks before sowing.
