1, comprehensive nutrition: lack of phlegm and phlegm, chelating fertilizer added 35% of the chelated reaction of calcium, sulfur, magnesium, iron, zinc, boron and other trace elements, can be directly absorbed by the crop.
2. Phosphorus and potassium release: Chelating fertilizer can promote the activation of phosphorus, potassium and trace elements in the soil that are not easily absorbed by crops, and convert them into active components that are easily absorbed by crops.
3. Sustained release controlled release: This product is added with urease inhibitor and polymeric amino acid. It is a chelated controlled release fertilizer with the advantages of organic fertilizer and high efficiency of controlled release fertilizer. It has sustained release and controlled release of nitrogen fertilizer. effect.
4. Improve fertilizer efficiency: Chelating fertilizer can promote the photosynthesis of crops and the complementation of various nutrients, promote root development, and improve the balanced absorption capacity of plants for various nutrients. The comprehensive utilization rate of nitrogen, phosphorus and potassium is increased by 20%-35%.
Compound fertilizer refers to a fertilizer with two or more nutrients. Such as potassium nitrate, ammonium dihydrogen phosphate (NH4H2PO4), potassium dihydrogen phosphate (KH2PO4), etc. Nutrients refer to nitrogen, phosphorus, potassium.
