Value of Magnesium Sulfate for Agricultural Applications
Magnesium sulfate is a two-element fertilizer (containing Mg and S), sulfur and magnesium are medium nutrient elements, which are necessary to increase crop yield and improve quality. Magnesium is the sixth major nutrient element of crops, is a component of chlorophyll and pigments, is a metal element in the chlorophyll molecule, magnesium is the activator of a variety of enzymes; magnesium is a necessary component of the polyribosomes, and is to promote the formation of vitamins A and C in the crop. Magnesium promotes photosynthesis and the formation of carbohydrates proteins and fats. Magnesium is also the activator of hundreds of enzymes, also involved in the composition of enzymes, to promote the metabolism of crops, magnesium can improve the crop's ability to resist disease, to prevent the invasion of pathogens, to increase crop yields and improve the quality of agricultural products. In addition magnesium also promotes the uptake of silicon in plants. The distribution of magnesium in crops is generally highest in seeds, secondary in stems and leaves, and least in roots.
Magnesium sulfate not only increases yield for crops, but also improves the taste of crop fruits. Magnesium also promotes the formation of vitamin A and vitamin C within the crop, thus improving the quality of fruits, vegetables and other crops, and sulfur is also necessary for the synthesis of amino acids, proteins, cellulose, and enzymes in crops.
In general, legume crops contain more magnesium than cereal crops, and magnesium uptake in tuberous crops is usually twice that of cereal crops. Rice, peanut, sesame in field crops, citrus, banana, pineapple, tobacco in cash crops, and potato, tomato, cucumber in vegetables are crops that require more magnesium. Magnesium sulfate as a fertilizer, can be used directly as a base fertilizer, follow-up fertilizer and foliar fertilizer, can be applied alone, or as one of the components of the mixing use, can be used in the traditional agricultural field can also be used in the field of high-value-added precision agriculture, flowers and soilless cultivation.
According to the "2019 China Magnesium Sulfate Industry Development Research and Development Trend Analysis Report" released by China Industry Research Network, it is expected that in the next few years, domestic magnesium sulfate products in addition to continue to meet the demand in the traditional fields of food, pharmaceuticals, chemicals, light industry, textiles, daily chemical and other needs and export of foreign exchange, there is still a huge potential market for agricultural fertilizers, and the demand for it will be a year-on-year upward trend, so we have to So we need to set up a correct fertilization concept, to achieve balanced nutrition, with the help of fertilizers, "reduce fertilization and increase efficiency" strategic background, the concept of healthy fertilization to the planting industry, is imperative.
