The healthy growth of plants needs not only a lot of nitrogen, phosphorus and potassium, but also medium elements such as calcium, magnesium and sulfur, and trace elements such as iron, manganese, zinc and copper. People often only pay attention to the application of nitrogen, phosphorus and potassium, but ignore calcium, magnesium, sulfur and trace elements.

Calcium: non protoplast (cell wall and free space), as well as components of biofilm, plays a role in stabilizing biofilm; it is also conducive to the extension of crop roots. Magnesium: it is an indispensable part of chlorophyll. Magnesium in crops, as a central ion, combines into the four pyrrole ring structure of chlorophyll. So it's very important for the synthesis of chlorophyll and the absorption of magnesium.

Dolomite is mainly suitable for acid soil. The application of dolomite can effectively improve the pH value of acid soil solution with calcium and magnesium deficiency, reduce the concentration of hydrogen ion and aluminum ion, and increase the concentration of calcium and magnesium ion in soil solution.

Our dolomite granular is made of dolomite by crushing and granulating. It can meet the needs of golf courses, municipal greening and park lawn to supplement calcium and magnesium, and improve the soil acid environment.

Size: 0.3-1.0mm(green grade), 1.0-2.5mm(fairway grade).

Application rate: for green grade, 25g/m²; for fairway grade, 45g/m².

The main ingredients of dolomite are calcium carbonate and magnesium carbonate. It has the following characteristics:

• Neutralize the hydrogen ion in soil solution and increase the pH value;
• Rapidly replenish calcium and magnesium ions in acid soil solution;
• Promote the absorption and utilization of other nutrients by crop roots;
• The particles are uniform and easy to use;
• It disintegrates rapidly in water.
