Parameters
Dipotassium Hydrogen Phosphate (DKP)
00-31-40
Dipotassium phosphate
Chemical formula: K2HPO4, K2HPO4.3H2O
Molecular weight: 174.18, 228.22
CAS No.: 7785-11-4
Executive standard: HG/T4510-2013 (industrial grade), GB25561-2010 (food grade)
Properties: Dipotassium hydrogen phosphate trihydrate is a white crystal with water. Anhydrous is white powder.
Purpose:
1. Alkaline phosphorus and potassium fertilizers can promote fruit expansion, improve fruit quality, increase coloring, and improve quality
2. It has the function of biological scheduling agent to promote the differentiation of crop buds and root development
3. PH value is weakly alkaline, which can be used to adjust soil acid-base balance
4. It is processed by thermal phosphoric acid process, which has high purity and fast absorption, and can be safely used in various crops
5. Completely dissolve in water, the dissolution speed is fast, and it does not block irrigation and spray equipment. Free of chlorine and sodium, low EC value, high safety
Packing: inner plastic outer woven, net weight 25Kg, 50Kg, 1000Kg per bag, stored in a ventilated and dry place.
