🌿 What is Magnesium Sulfate?
Magnesium sulfate (MgSO₄) is an important inorganic salt used extensively in the fertilizer industry. It provides two essential nutrients: magnesium (Mg) and sulfur (S), both of which are vital for plant development and agricultural productivity.
Available mainly as magnesium sulfate heptahydrate (MgSO₄·7H₂O), it is highly water-soluble, making it ideal for various fertilizer formulations.
🧪 Function of Magnesium in Plants
Magnesium is the core component of chlorophyll, enabling plants to convert sunlight into energy through photosynthesis.
It activates enzymes necessary for carbohydrate, protein, and fat formation.
Deficiency symptoms include interveinal chlorosis, stunted growth, and leaf drop.
🌾 Importance of Sulfur
Sulfur is a building block for amino acids like cysteine and methionine.
It contributes to protein synthesis, enzyme function, and oil formation.
Sulfur deficiency results in pale green leaves, delayed maturity, and reduced yield.
