What are the uses of ammonium sulfate? What should I pay attention to when using it? Also ask netizens to help introduce the farming network to sort out the use of ammonium sulfate in agriculture and points for attention, listed below for netizens' reference. The main agricultural uses of ammonium sulfate are: 1, used as crop base fertilizer: ammonium sulfate as base fertilizer should be deeply applied to cover soil to facilitate crop absorption. 2. Used as topdressing for crops: ammonium sulfate is the most suitable for topdressing for crops. The topdressing amount of ammonium sulfate should be determined according to different soil types. For the soil with poor performance of water and fertilizer conservation, it should be applied by stages, and the dosage should not be too much each time; for the soil with good performance of water and fertilizer conservation, the amount should be more each time. The amount of soil moisture also has a great influence on fertilizer efficiency, especially in dry land, we must pay attention to timely watering when applying ammonium sulfate. As for the paddy field as topdressing, it should be drained and dried first, and should be applied at the same time with ploughing and raking. In addition, there are obvious differences in the application of ammonium sulfate to different crops, such as trench application, ring application or hole application when used in fruit trees. 3. It can be used as seed fertilizer when planting crops: because ammonium sulfate has no adverse effect on seed germination. Matters needing attention when ammonium sulfate is used in crop cultivation: first, ammonium sulfate fertilizer should not be contacted or mixed with other alkaline fertilizers or alkaline substances in order to prevent the fertilizer efficiency from being reduced. Second, it is not suitable to apply ammonium sulfate on the same cultivated land for a long time, otherwise the soil will become sour and cause hardening. If it is really needed, some lime or organic fertilizer can be applied together with appropriate amount. However, it must be noted that ammonium sulfate and lime can not be mixed to prevent ammonium sulfate from decomposing and causing nitrogen loss. Generally speaking, the combined application of the two should be 3-5 days apart. Note that ammonium trisulfate is not suitable for application in acidic soil.
