Characteristics of NPK fertilizer
Its nutrient characteristics are: nitrogen is active and not easy to accumulate in soil, so it needs to be applied frequently for nitrogen fertilizer. After phosphorus and potassium are applied to the soil, they are mainly accumulated in the soil besides being absorbed by crops. Long-term and large-scale application will gradually increase the soil nutrient content, thus reducing the demand, and the proportion of phosphorus and potassium demand will decrease. Therefore, the nutrient elements of nitrogen, phosphorus and potassium should be treated differently. For nitrogen, its content in the soil should be constantly regulated. For phosphorus and potassium, the after-effect of fertilizer should be considered, and its accumulation in the soil should be paid attention to to prevent excessive.
