NPK 20-20-20+te Water Soluble Fertilizer For Irrigation Use
Characteristics: Nitrogen is active and not easy to accumulate in dao soil, so it needs to be applied frequently for nitrogen fertilizer. In addition to being absorbed by crops, phosphorus and potassium are mainly accumulated in the soil after being applied to the soil. Long-term large-scale application will gradually increase soil nutrient content, thereby reducing demand, and the proportion of phosphorus and potassium demand will decrease. Therefore, the nutrient elements of nitrogen, phosphorus and potassium must be treated differently. For nitrogen, its content in the soil must be continuously adjusted.
