Application of dolomite powder in aquaculture and agriculture?

The progress of technology makes the use of snow white products more and more widely. Dolomite powder can be used to improve the dust flying in coal mines and prevent and delay the explosion of coal dust. It is used as a filter material for water treatment, especially for neutralization from drinking water to industrial water, swimming pool water, etc., and for removing iron, manganese and silicate.

Calcium and magnesium are essential nutrients in animals. Adding appropriate powder to animal and poultry feed is very beneficial to promoting animal growth and reducing disease. However, the fineness of the powder and the content of harmful elements must be strictly controlled.

Acidity used in agriculture and soil. Because urea and other fertilizers are easy to acid the soil for a long time, it can be added directly to urea to keep the soil at the appropriate pH, which usually increases crop yield by 15-40 times. When pH is 6.0 to 6.2, the efficacy of herbicide can be improved.

It can also compensate for the loss of magnesium content in soil. The powder from 1.2 to 0.8um can flow freely. It can be used as fertilizer filler to improve the conditions of plant utilization of soil nutrients, reduce the caking and adjust the fertilizer ratio.

In recent years, with the development of magnesium smelting industry, more and more tailings occupy farmland and increase environmental load. How to make full use of these resources has found a better way out, that is, the tailings after smelting magnesium metal with dolomite powder are used to produce magnesium oxide compound fertilizer. In addition, it is reported that it can be used instead of serpentine to produce calcium magnesium phosphate fertilizer.
