Application of ammonium sulfate

1、 Agricultural sector: Efficient nitrogen and sulfur fertilizers

Core fertilizer efficiency characteristics

With a nitrogen content of 20%~21% and a sulfur content of 24%, it serves as both a nitrogen and sulfur source, making it particularly suitable for sulfur deficient soils and sulfur loving crops such as rice, wheat, and cotton

Quick acting and long-lasting: effective 3-7 days after application, fertilizer effect lasts 50-60 days, significantly longer than ammonium bicarbonate (15 days) and ammonium chloride (25 days)

Physiological acidity: can neutralize alkaline soil and improve the structure of calcareous soil, but long-term single application may lead to soil compaction in acidic soil, requiring the combination of organic fertilizer or lime

Application scenarios and methods

Base fertilizer: Apply deep covering soil (such as 15-20cm in dry land) to promote root absorption

Seed fertilizer: Mix with organic fertilizer (e.g. 5kg ammonium sulfate+25kg organic fertilizer/acre) to avoid salt damage affecting germination

Topdressing:

Dryland: combined with watering to prevent volatilization; Paddy field: drainage before application, tillage and harrowing to improve utilization rate

Soil with poor fertility requires a small amount to be applied multiple times (such as 3-4 times for sandy soil)

Efficiency Enhancement and Taboos

Yield increasing effect: Promote branch and leaf growth, improve fruit quality and stress resistance (such as lodging resistance and disease resistance)

Disable scenario:

Avoid mixing with alkaline fertilizers (such as plant ash) to prevent ammonia volatilization and nitrogen loss

Acidic soil requires controlled amount (accelerated acidification at pH<6)
