What is the methed? (1) As base fertilizer.
Deep covered, for Facilitating crop uptake.
(2) As additional fertilizer.
The soil which has worse performance for the conservation of water and fertilizer, fertilize by stages and should not be too much at a time. The soil which has better performance for the conservation of water and fertilizer, we can increase the dosage appropriately.
Soil moisture content has great influence to fertilizer efficiency, especially the dry land. Must pay more attention to watering timely when fertilization. For paddy field, should drain away water first, and apply plowing at the same time. Moreover, Different crops have obvious differences in fertilizer efficiency, such as used for fruit tree, can use ditch, ring or hole methods.
(3) As seed fertilizer. As ammonium sulfate have no adverse effects on seed germination.
