As a common nitrogen fertilizer, ammonium sulfate is widely used in agriculture. However, the correct application of ammonium sulfate requires scientific guidance and strict operating procedures to ensure its positive impact on crop growth and avoid potential risks.
Ammonium sulfate (chemical formula: (NH 4 ) 2 SO 4 ) is a high-quality nitrogen fertilizer with a nitrogen content of up to 21%, good water solubility and stability. It not only provides nitrogen required by crops, but also supplements sulfur, which has a positive effect on crop growth and soil improvement.
Ammonium sulfate is suitable for a variety of crops, including food crops (such as wheat and corn), cash crops (such as cotton and tobacco), vegetables, and fruit trees. It is particularly effective for crops that require large amounts of nitrogen and sulfur.
The application amount should be determined according to soil fertility and crop needs. Generally speaking, it is recommended to apply 5-10 kg of ammonium sulfate per mu of land, combined with other fertilizers. The frequency of fertilization should be adjusted according to the growth cycle of the crop to ensure a continuous supply of nutrients.
1. Soil preparation: Before applying ammonium sulfate, conduct a soil test to understand the soil pH and nutrient content.
2. Fertilization method: You can choose basal application, topdressing or broadcasting. For basal application, spread ammonium sulfate evenly on the soil surface, then turn the soil and mix; for topdressing, apply it when the crop begins to grow to enhance its growth momentum.
3. Note: Avoid applying fertilizers in hot weather or before or after heavy rain to prevent nutrient loss or adverse effects on crops.
Although ammonium sulfate is a commonly used fertilizer, appropriate protective measures must still be taken during its application:
1. Personal protection: Wear gloves, masks and eye protection to avoid skin contact and inhalation of dust.
2. Storage management: Store ammonium sulfate in a cool, dry, well-ventilated place to avoid moisture or high temperature.
Case 1: Through the scientific application of ammonium sulfate, a corn planting base in a certain place increased the yield per mu by 15% and significantly improved the sulfur content of the land.
Case 2: Through repeated small-scale application of ammonium sulfate, the fruit quality of an orchard was significantly improved, and the market price increased by 20%.
Correct application of ammonium sulfate can effectively increase crop yield and quality while improving soil conditions. Farmers need to strictly follow scientific application methods and safety protection measures to ensure the sustainable development of agricultural production.
