 Superphosphate surface application for topdressing

Phosphorus in the soil mobility is small, generally in the application point 0.5 cm, the movement range of 1~3 cm. Therefore, it is difficult for surface application to reach the rhizosphere of crops, so it cannot supplement the phosphorus element in crops.

Urea immediately after the broadcast watering

Urea is an acylamide nitrogen fertilizer, easily soluble in water, after being applied to the soil, it can be converted into ammonium bicarbonate after decomposition, which can be absorbed and utilized by crops. Immediately after surface application, water is watered, which is easy to make urea lose with water and reduce fertilizer efficiency.
