The solubility of the effective components of a fertilizer in water is usually a measure of the effectiveness of a fertilizer. Grade is the main indicator of fertilizer quality, it refers to the percentage of effective nutrients or their oxides in fertilizer products, such as: nitrogen, phosphorus, potassium, calcium, sodium, manganese, sulfur, boron, copper, iron, molybdenum, zinc.
Phosphate fertilizer, Nitrogen Fertilizer and potassium fertilizer are chemical fertilizers with large plant demand.
