Magnesium sulfate also has a beauty effect in green leafy vegetables! Before cultivating the land, use 10-15 kg of magnesium sulfate mixed with decomposed farm manure or organic fertilizer per mu of land, mix well and spread. Topdressing: Use 10-13 kg of magnesium sulfate per acre of land to flush calcium nitrate sol into the crop field with water, if it is a fruit tree, apply 250-500 g of magnesium sulfate per plant. Foliar fertilizer: different crops spray concentrations are different. As a chemical fertilizer, magnesium sulfate is mainly used in red soil areas and dissolved areas, and has a particularly obvious effect on rubber trees, fruit trees, tobacco leaves, beans, vegetables, potatoes and other crops. Magnesium is one of the components calcium ammonium nitrate price of chlorophyll in fertilizers, which can strengthen the plant reduction process and promote the activation of enzymes. Magnesium sulfate is an ideal raw material for the manufacture of compound fertilizer, it can be mixed with nitrogen, phosphorus and potassium into compound fertilizer or mixed fertilizer according to different needs, and can also be mixed with one or more elements into various fertilizers and photosynthetic micro-fertilizers, magnesium-containing fertilizers are most suitable for acidic soil, peat soil and sandy soil. After the comparative fertilization test of the actual fertilization of nine crops such as rubber trees, fruit trees, tobacco leaves, beans and vegetables, potatoes, cereals, etc., the compound fertilizer containing magnesium can increase the crop by 15-50% compared with the compound fertilizer without magnesium. 
How is magnesium sulfate used in agriculture?
1. Magnesium sulfate contains the sulfur and magnesium elements needed in the growth process of crops, which can generally be used as base fertilizer, topdressing and foliar fertilizer in agriculture, which can increase yield and improve crop quality.
2. Base fertilizer: use 10-15kg of magnesium sulfate per mu of land before ploughing the land mixed with decomposed farm manure or organic fertilizer, stir well and then spread.
3. Topdressing: use 10-13kg of magnesium sulfate per acre of land to wash into the crop field with water, if it is a fruit tree, apply 250-500g of magnesium sulfate per plant.
4. Foliar fertilizer: fruit trees, spray concentration of 0.5%-1%; Vegetables, spray concentration of 0.2%-0.5%; Rice, cotton, corn: spray concentration of 0.3%-0.8%, generally spray 50-150kg of magnesium sulfate solution per mu.
5. The use of magnesium sulfate solution, for fruit trees, generally in magnesium nitrate hexahydrate the fruit stage is the best to use, for vegetables, rice, corn and other crops, generally in the seedling stage is better to use; When using, it is best to mix with farm manure and organic fertilizer, and the effect is better.
