Urea contains the most nitrogen among nitrogenous fertilizers, with 46% nitrogen in its content. It dissolves easily in water, is white in color and has round grains.
After urea fertilizer is applied to the soil, the organic nitrogen in it undergoes chemical changes in the soil and becomes available to plants in a short time. Urea can be applied successfully to all plants. While it can be used in autumn fertilization, it can also be used during certain growth periods of plants, in spring or later.
When a large amount of urea needs to be administered, it should be divided into several portions rather than all at once. After urea is applied to the soil, it should be mixed into the soil immediately. Otherwise, nitrogen loss may occur from the fertilizer remaining on the soil surface.
