What are the Uses of Ammonium Sulfate?

  Those who farm in rural areas are probably no strangers to ammonium sulfate, which is a relatively high-quality nitrogen fertilizer for many crops. What are the uses of ammonium sulfate? What are the technical points of applying ammonium sulfate?

1. What are the uses of ammonium sulfate?

①This is an excellent nitrogen fertilizer (commonly known as fertilizer field powder), suitable for general soil and crops, which can make branches and leaves grow vigorously, improve fruit quality and yield, and enhance the resistance of crops to disasters.

②Ammonium sulfate also has many uses in biology, mostly used in protein purification process, because ammonium sulfate belongs to the inert material, not easy to react with other biologically active substances, in the purification process can maximize the protection of protein activity, in addition, ammonium sulfate solubility is very good, can form a high salt environment, for protein precipitation and the subsequent high salt purification to make preparations. There is a big difference between the solubility of ammonium sulfate at 0℃ and 25℃ at room temperature.

2. Technical points for the application of ammonium sulphate

①Ammonium sulfate should not be applied to flooded fields. This is because under flooded conditions, the soil will be severely deprived of oxygen and the sulfate ion will be reduced to sulfide. Excessive accumulation of sulphide concentration causes plant root damage and death.

②Ammonium sulfate belongs to the acidic fertilizer, long-term large-scale application of soil acidity increases, applied on acidic soil should be combined with grass ash or calcium and magnesium, phosphorus fertilizer, sheep manure mushroom fertilizer these alkaline fertilizers, but not at the same time, need to be spaced out for about a week or so, or reduce the effectiveness of fertilizer.

③Ammonium sulphate is not suitable for long term application in large quantities on the same plot, otherwise the soil will become acidic causing sloughing.

④Tests prove that ammonium sulphate is effective in increasing yields when applied to pungent crops. Applying small amounts of high potassium fertilizer multiple times to grape and strawberry fields has a significant yield increase effect.
