Ammonium sulfate ((NH₄)₂SO₄) is a common agricultural fertilizer that is rich in nitrogen and sulfur, two essential nutrients for plants. Ammonium sulfate not only provides essential nutrients to crops, but also enhances soil fertility, thereby promoting healthy plant growth.
Ammonium sulfate can significantly enhance the disease resistance of vegetables. Sulfur is a component of certain disease-resistant proteins and enzymes in plants and can effectively reduce the occurrence of diseases. Studies have shown that vegetables using ammonium sulfate show higher resistance to diseases such as downy mildew and powdery mildew.
The nitrogen in ammonium sulfate is an indispensable nutrient in the growth process of vegetables. It can promote the formation of chlorophyll, enhance photosynthesis, and thus accelerate the growth of plants. In addition, sulfur improves soil quality and promotes root development, allowing plants to better absorb water and nutrients.
When applying ammonium sulfate, scientific fertilization must be carried out according to the specific conditions of the soil and vegetables. It is generally recommended to apply 10-15 kg per acre of land. Excessive use may cause soil acidification and affect the normal growth of vegetables.
Ammonium sulfate should be applied in stages during the plant growth period. It is generally recommended to apply once before sowing, during the seedling stage and during the growth stage, and irrigate fully after each application so that the fertilizer can be fully dissolved and absorbed by the plants.
Ammonium sulfate can be applied by broadcasting, furrowing and top dressing. When broadcasting, pay attention to even distribution and timely plowing of soil to cover; when applying furrow and top dressing, ensure good contact between the fertilizer and the root system, and pay attention to irrigation to prevent fertilizer loss.
Although ammonium sulfate has many advantages, you still need to pay attention to the following points during use:
As an efficient nitrogen fertilizer, ammonium sulfate can significantly improve the disease resistance and growth rate of vegetables. However, scientific fertilization and reasonable dosage are the keys to ensuring its effectiveness. The correct use of ammonium sulfate can not only improve the yield and quality of vegetables, but also promote the sustainable development of agriculture.
