Granular kieserite magnesium sulphate fertilizer

Granular kieserite is a dual-element fertilizer (containing mg and s), both sulfur and magnesium are

secondary nutrients, which are necessary for crop production and quality improvement.

Magnesium is the sixth largest nutrient element of crops. It is a component of chlorophyll and pigments.

It is the only metal element in chlorophyll molecules. Magnesium is an activator of various enzymes;

The formation of a and c, magnesium can promote photosynthesis, and promote the formation of

carbohydrates, proteins and fats. Increase the yield of crops and improve the quality of agricultural

products. In addition, magnesium can also promote the absorption of silicon by plants.

The distribution of magnesium in crops is generally the highest in seeds, followed by stems and leaves,

and the least in roots. In general, legumes contain more magnesium than grasses, and root crops

usually absorb twice as much magnesium as cereals. Field crops of rice, peanuts, sesame,

commercial crops of citrus, bananas, pineapples, tobacco, and vegetables such as potatoes and

tomatoes are all crops that require more magnesium.

1. Principles of application for granular kieserite:

(1) First used in magnesium-deficient soil. When the available magnesium content of the soil is

60-120mg/1, it is a magnesium deficient area; when the available magnesium content of the soil is

less than 60mg/1, it is a severe magnesium deficiency area, and magnesium fertilizer should be

applied in time.

(2) It is first used in crops that require more magnesium. The crops that need more magnesium are

economic crops, such as trees, vegetables, cotton and leaf cash crops such as mulberry, tea tree,

tobacco, etc. The second is leguminous crops such as soybeans and peanuts.

(3) Choose magnesium fertilizer varieties according to soil pH. For neutral and alkaline soils, it is

advisable to use quick-acting physiologically acidic magnesium fertilizers, such as magnesium sulfate;

for acidic soils, it is advisable to use slow-acting magnesium fertilizers, such as granular kieserite.
