Product Description
- 产品描述
-
Potassium nitrate granules are primarily characterized by their non-caking property and leave no harmful residues after dissolving. The nitrate nitrogen and potassium they contain are both essential macronutrients crucial for crop growth, and these elements exhibit excellent synergy—mutually enhancing each other’s absorption by crops while also facilitating the uptake of other vital nutrients. Moreover, the fertilizer boasts an ideal nitrogen-to-potassium ratio of 1:3 (a ratio commonly absorbed by most crops), enabling crops to efficiently and rapidly take up these nutrients during peak demand periods. Additionally, potassium nitrate granules have a low salt index, dissolve readily in water without absorbing moisture, and deliver high nutrient concentrations with swift fertilizing effects. Using potassium nitrate granules not only boosts yields and improves crop quality but also promotes earlier maturity, strengthens disease resistance, and extends shelf life. This versatile fertilizer is widely applied across various economic crops, making it especially suitable for tobacco cultivation.
Product characteristics:
Potassium nitrate granules are colorless and transparent, completely soluble in water, but insoluble in ethanol and diethyl ether. They are also not easily deliquescent when exposed to air.Technical specifications:
