What are the ways of applying urea?

The application of urea to the farmland can be done with basal fertilizers and top dressings rather than with seed fertilizers. When urea is used as base fertilizer, attention should be paid to two points. The first application of deep basal fertilizer is to cover the soil. Do not apply water immediately after application to prevent the urea from leaching into the deep layer. Applying urea as a basal fertilizer on dry land must be applied to a certain depth of soil, especially on calcareous soils with slightly alkaline soils. If urea is applied, the volatilization loss of ammonia may be more serious than ammonium bicarbonate. The second application amount should be carefully planned, because urea is a high-concentration nitrogen fertilizer, and the application amount of basal fertilizer is generally 8-10 kg/mu.
