Composition and advantages of NPK compound fertilizer

NPK compound fertilizer is composed of three main nutrients: nitrogen (N), phosphorus (P) and potassium (K). It is an indispensable fertilizer in modern agriculture. Its advantage is that it can provide comprehensive nutrition for plants, promote root growth and increase crop yields.

Composition Analysis of NPK Compound Fertilizer

1. **Nitrogen (N)**: Promotes the growth of plant leaves and improves the efficiency of photosynthesis.
2. **Phosphorus (P)**: Enhances plant root development and promotes flowering and fruiting.
3. **Potassium (K)**: Improves plant resistance and enhances the taste and preservation of fruits.

Tips for using NPK compound fertilizer

In order to maximize the effect of NPK compound fertilizer, the following application principles should be followed:

1. **Scientific application**: Adjust the fertilization plan according to the soil test results to meet the nutritional needs of the plants.
2. **Application in batches**: Fertilizer can be applied in multiple batches to avoid plant damage caused by excessive concentration at one time.

Application time

The best time for application is spring and autumn. Application in spring can promote growth, while application in autumn can help accumulate nutrients in the root system.
