Types of Agricultural Chemicals
The agricultural chemicals produced by our company mainly include the following types
Magnesium Sulphate Heptahydrate
Ordinary sodium nitrite: white little crystals or light yellow. Dry powder sodium nitrate: white crystal,non-caking, showing loose status.
Npk Compound Fertilizer
Made of high quality ingredients. Consists of 100% plant nutrients. Virtually free of chloride, sodium and other detrimental elements for plants. Provides balanced, complete plant nutrition. Available in a wide range of formulae. It was produced from pure raw materials which doesn't contain any toxic and radioactive substance.

Magnesium Sulphate Heptahydrate
Magnesium sulphate heptahydrate have many advantages, including: Magnesium sulphate heptahydrate (Epsom salt) offers advantages as a versatile compound with applications in agriculture, medicine, and industry due to its high solubility and bioavailability. It is used to correct soil deficiencies in magnesium and sulfur, boost plant growth, and is also used in pharmaceutical and industrial processes.
Npk Compound Fertilizer
Npk compound fertilizer have many advantages, including:
★Nutrient elements: NPK Compound fertilizer has high nutrient content and many types of nutrient elements. One application of compound fertilizer can supply at least two or more main nutrient elements to crops at the same time.
★Uniform structure: The nutrient distribution of NPK fertilizer is relatively uniform. After forming particles, compared with powdered or crystalline unit fertilizers, it has a compact structure, uniform nutrient release, and stable and long fertilizer effect. Due to the small number of by-products, it has little adverse effect on the soil.
★Uniform fertilization: Compound fertilizer particles are uniform, each particle contains multiple elements, and the fertilizer is spread more evenly. It can be applied at one time. Other mixed fertilizers: if urea, diammonium, and potassium fertilizers, they need to be mixed manually before use.
Application of Agricultural Chemicals
1.Magnesium Sulphate Heptahydrate
Magnesium sulphate heptahydrate can be used for a variety of purposes, including:
★Magnesium sulphate heptahydrate is used in industry: In printing and dyeing industry,it can be used as fabric dyeing agent, weighting agent, mordant, and the aggravating reagent of calico or silk, and filling up of wooden-cotton products. It can be used as a filler to enhance heat resistance in leather industry; used for fireproof material making.
★Magnesium sulphate heptahydrate is used in agriculture and gardening fertilizer: It is applied to magnesium deficient soil, soluble in the water, absorbed by the soil, to make it fertile. As a key component of chlorophyll molecule, it absorbs sunlight, utilizing the light energy for providing food nutrients for plants during photosynthesis, which can strengthen nutrition to increase the output and crop growth.
2.Npk Compound Fertilizer
★Npk compound fertilizer can be used for a variety of purposes, including: High N series for start stage and some vegetables like spinach and cabbage. High P series for appling after transplanting and for crops like beans. High K series for later stage and crops like potato, tomato, tabacco. It is usually used as top dressing and can also be used as base manure and seed manure. This product is extensively applied to grain crops like paddy, wheat, corn and sorghum and to cash crops including tobacco, tea, cotton, gourds, fruits and vegetables
