Magnesium sulfate heptahydrate

1. Provide essential nutrients: Magnesium sulfate contains sulfur and magnesium elements necessary for crop growth. Magnesium is a component of chlorophyll and is crucial for photosynthesis; Sulfur is an important element in the synthesis of proteins and amino acids.

2. Promoting crop growth: Moderate application of magnesium sulfate can increase crop yield and improve crop quality. Magnesium can promote the formation of carbohydrates, proteins, and fats in crops, while sulfur is essential for the synthesis of nutrients such as amino acids, proteins, and cellulose.
