MANGANESE SULPHATE APPLICATION IN FERTILIZERS

Manganese sulfate is an important micronutrient fertilizer, primarily providing crops with the essential manganese element. Manganese plays a crucial role in the physiological processes of crops, including photosynthesis, enzyme activation, and nitrogen metabolism.

1. Main Functions of Manganese Sulfate Fertilizer

Participates in Photosynthesis: Manganese is a component of chloroplasts and directly participates in the hydrolysis reaction during photosynthesis. Manganese deficiency leads to chlorosis in leaves.

Activates Enzyme Systems: Manganese is an activator or component of many enzymes, participating in processes such as respiration and nitrogen metabolism (nitrate reduction) in crops.

Promotes Seed Germination and Seedling Growth: Sufficient manganese promotes seed germination, resulting in robust seedlings and well-developed root systems.

Enhances Stress Resistance: Improves crop resistance to certain diseases (such as wheat rust) and adverse environmental conditions (such as low temperatures).

Improves Quality: For cash crops, it can increase vitamin C content, sugar content, etc., improving fruit quality.

2. Typical Symptoms of Manganese Deficiency

Understanding the symptoms of manganese deficiency is a prerequisite for the rational application of manganese sulfate. Manganese deficiency first appears on new leaves.

Common characteristics: Interveinal chlorosis occurs in leaves, resulting in yellow or yellowish-white streaks, but the veins and surrounding areas remain green, exhibiting a "rib-like" or "reticulated" yellowing. In severe cases, the chlorotic areas turn grayish-white and necrotic spots appear.

Specific crop examples:

Soybean: "Gray spot disease," new leaves show interveinal chlorosis, and the leaves turn grayish-white or reddish-brown.

Wheat: "Gray spot disease" or "white wilt," leaves show gray or light yellow streaks.

Corn: New leaves show yellow streaks parallel to the veins.

Fruit trees (e.g., apples, citrus): Interveinal chlorosis occurs, but the main vein remains green; in severe cases, leaves fall off prematurely.

Vegetables (e.g., tomatoes, potatoes): New leaflets show interveinal chlorosis, and the leaves become wrinkled.

Farmers in Southeast Asia and Latin America, who are dealing with soils that have become more acidic due to heavy rainfall and intensive farming, are saying that their crops are stronger and more nutritious after using MgO-based amendments. As governments encourage farmers to use methods that don't harm the environment by giving them money, more and more people will want to buy products that improve soil. This makes MgO an important part of farming in the future.
