How is magnesium sulfate used in agriculture? Before cultivating the land, use 10-15 kg of magnesium Magnesium Sulphate producer 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 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.

1. Magnesium sulfate contains the sulfur and magnesium elements needed in the growth Magnesium Oxide MgO 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 the fruit Magnesium Oxide powder 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.
