We have compiled the use and precautions of ammonium sulfate in agriculture, which are listed below for your reference.
The main uses of ammonium sulfate in agriculture are:
1. Used as a base fertilizer for crops:
When ammonium sulfate is used as the base fertilizer, deep application of soil is required to facilitate crop absorption.
2. Used as a top dressing for crops:
Ammonium sulfate is most suitable for use as a top dressing for crops. The amount of topdressing of ammonium sulfate should be determined according to different soil types. For soils with poor water retention and fertilizer retention performance, it should be applied in stages, and the dosage should not be too much. For soils with good water retention and fertilizer retention, each dosage should be appropriate.
The amount of soil moisture also has a greater impact on fertilizer efficiency, especially in dry land. When applying ammonium sulfate, it is necessary to pay attention to timely watering. As for the paddy field for topdressing, it should be drained and dried first, and attention should be paid to the combination of tillage and application. In addition, there are also significant differences in the application of ammonium sulfate to different crops. For example, when used in fruit trees, it can be applied by ditching, ring application or acupoint application.
3, can be used as a fertilizer when planting crops:
Because ammonium sulfate has no adverse effect on seed germination.
Things to note when using ammonium sulphate for crop planting:
Note 1. Ammonium sulfate fertilizer should not be contacted or mixed with other alkaline fertilizers or alkaline substances to prevent reducing fertilizer efficiency.
Note 2. It is not advisable to apply ammonium sulfate for a long time on the same piece of cultivated land, otherwise the soil will become sour and cause compaction. If it is necessary to apply, some lime or organic fertilizer can be applied in an appropriate amount. However, it must be noted that ammonium sulfate and lime cannot be mixed to prevent decomposition of ammonium sulfate and cause nitrogen loss. Generally, the combined application of the two should be separated by 3-5 days.
Note that ammonium trisulfate is not suitable for application on acidic soils.
