Manganese sulfate mainly has the following uses in agriculture: 1.Trace element fertilizer: Manganese sulfate can be used as a source of manganese in trace element fertilizer. Manganese is one of the important trace elements required for plant growth and development. It participates in important physiological processes such as photosynthesis, respiration, and nitrogen metabolism, and promotes the growth and yield of plants. 2.Promote plant disease resistance: manganese sulfate can enhance plant disease resistance. Manganese ions can increase antioxidant capacity in plants and reduce the accumulation of harmful active oxygen, thereby protecting plants from pathogenic bacteria and damage from the external environment. 3.Improve fruit quality: Manganese sulfate can also improve fruit quality. Manganese participates in the activation process of enzymes in plants, and can promote the synthesis of sugar, vitamins and pigments in fruits, making the quality of fruits better. 4.Prevention of manganese deficiency: Manganese sulfate can be used as a fertilizer to prevent and treat manganese deficiency in crops. Manganese deficiency can lead to yellowing of the gaps between the leaves of the plant, scorching of the edge of the leaves, and even affect the growth and yield of the plant. NOTE: It should be noted that the use of manganese sulfate should follow the principle of rational fertilization and avoid excessive application to avoid adverse effects on the soil and the environment. The appropriate amount and time of fertilization should be determined according to the specific crop and soil conditions.1. Do your company have any official certification ? Yes.
