National Standard and effect of magnesium Sulfate Fertilizer

Potassium magnesium sulfate fertilizer is a kind of multi-element potassium fertilizer, which not only contains potassium, sulfur and magnesium, but also contains calcium, silicon, boron, iron, zinc and other elements, which is weakly alkaline, especially suitable for acid soil, generally as base fertilizer and as topdressing fertilizer. It is suitable for rice, corn, sugar cane, peanut, tobacco, potato, sugar beet, fruit, vegetable, alfalfa and other crops. Compared with the elemental potassium fertilizer potassium chloride and potassium sulfate with the same amount of potassium (K2O), the application effect of agricultural potassium magnesium sulfate is better than potassium chloride and slightly better than potassium sulfate.

National standard of magnesium sulfate fertilizer

On September 1st, 2007, the recommended national standard of potassium magnesium sulfate fertilizer (GB/T20937-2007) was formally implemented. The standard was drafted by the National Fertilizer quality Supervision and Inspection Center (Shanghai) and Qinghai CITIC Guoan Science and Technology Development Co., Ltd., and jointly issued by the State Administration of quality Supervision, Inspection and Quarantine of the people's Republic of China and the China National Standardization Administration. The implementation of the national standard of potassium magnesium sulfate fertilizer indicates that the production and sales of potassium magnesium sulfate fertilizer are expected to be standardized.

Effect of magnesium sulfate fertilizer

Magnesium sulfate fertilizer is one of the series products of multi-element potassium sulfate, and it is a very important fertilizer, which can not only provide magnesium and sulfur to plants, but also loosen soil, promote the growth and development of leaves, branches and roots of plants, and make the roots of plants big. at the same time, it can accelerate the absorption of nitrogen, phosphorus and other elements in the soil, and increase the ability of plants to resist diseases. It is called "nutrient for plant growth and high yield". Plants cannot grow normally without magnesium, so magnesium must be replenished in time to improve productivity and agricultural production. Magnesium is an important component of chlorophyll and is indispensable for photosynthesis. it is the activator of many enzymes and can promote carbohydrate metabolism, nucleic acid synthesis, phosphate conversion and so on.

Potassium magnesium sulfate fertilizer is a kind of natural mineral fertilizer, which is known as "platinum potassium" for crop fertilization and is a substitute for potassium sulfate. The natural ore containing potassium sulfate and magnesium sulfate is processed through several tedious processes. it is a natural green fertilizer which can provide comprehensive and balanced nutrients of potassium, magnesium and sulfur for crop growth. Magnesium is added to the function of traditional potassium sulfate products, which greatly promotes the most important photosynthesis in the process of crop growth. Magnesium plays an important role in crop growth, and it is the core component of chlorophyll. Crop growth mainly depends on photosynthesis, and it is chlorophyll that plays a decisive role in photosynthesis. Magnesium can also greatly promote the absorption of phosphorus by crops, promote the formation of crop growth enzymes, and then promote the formation of vitamins, carbohydrates, proteins and fats, and prevent early defoliation and fruit loss during maturity. The experimental results show that potassium magnesium sulfate fertilizer is suitable for all crops, especially for cash crops such as vegetables, fruit trees, tea and flowers, which can provide long-term stable fertilizer effect for crop growth and improve crop quality. enhance the ability of crops to resist drought, cold and drug damage, and the effect of increasing yield is very obvious.

Organic natural potassium magnesium sulfate fertilizer refers to potassium magnesium sulfate fertilizer which meets the recommended national standard (GB/T20937-2007) and has obtained organic product certification. CITIC Guoan Organic Natural potassium magnesium Sulfate Fertilizer fills the domestic gap of natural mineral potassium fertilizer and solves the difficult problem of potassium supplement in organic agriculture.
