As fertilizer
1. Description
Ammonium sulphate is one of the most widely used nitrogen fertilizers. Ammonium sulphate provides an equal balance of nitrogen and sulphur and can make crops thrive and improve fruit quality and yield and also strengthen resistance to disaster . Ammonium sulphate is the best fast releasing, quick acting and can be used directly for a wide range of soil and crops, and also as seed fertilizers, base fertilizer and additional fertilizer.
2. Method
(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.
3. Attention
(1) In case of lower fertilizer efficiency, can't contact with other alkaline fertilizer or substances.
(2) In order to avoid cause soil harden and acidification, Should not be long-term use of ammonium sulfate on the same piece of farmland. If you have to use fertilizer, you can add some lime or organic fertilizer appropriately.
in order to prevent the decomposition of ammonium sulfate, must pay attention to not mixed with lime. General apply the two to 3 ~ 5 days apart.
(3) Not suitable for acid soil.
