Potassium dihydrogen phosphate（agricultural）KH2PO4
Content :92%-----96%
Product use : Potassium dihydrogen phosphate for agriculture is some phosphorus kalium compost of high concentration and potash manure none of chlorine of high-quality, containing 48%--50% P2O5,31%--33% K2O,and the total effective nutrient counts up to 48%--85%. It mainly acts on the base of crops and leaf area on anaphase, applicable abroad for foodstuff, melon andfruit, vegetable(such as paddy,wheat,corn,soy,cotton,flax,fruit,greenstuff,baccy,etc),special for baccy,orange, tea…which abstain from chlorine. Potassium dihydrogen phosphate is the fertilizer appointed to popularize by state agricultural department.
Product quality: increase production greatly, improve quality, boost up immunity to pest,drought,collapse and so on. For fruit such as orange it can short the time of ripe ,add sirup and so on..
