4、How To Make Npk Compound Fertilizer

When preparing NPK fertilizer, two primary methods are widely used: the NPK fertilizer granulation line and the NPK fertilizer blending system. The granulation line transforms powdered chemical fertilizers into pellets, while blending combines granular materials evenly.

Let’s start with a basic explanation about the NPK nutrients and their percentages (%) in fertilizer formulae. Fertilizer's formula usually refers to the content of nutrients in their oxide forms (N-P2O5-K2O).

Formulating and applying NPK compound fertilizer is a critical step in agricultural planting, directly impacting crop growth and yield. Below are the detailed steps for formulating NPK compound fertilizer:

1. Understand Requirements: First, determine the specific nutrient needs of the crops, including the required ratios of nitrogen (N), phosphorus (P), and potassium (K). Generally, the proportion of nitrogen fertilizer is about 20%-30%, phosphorus fertilizer 5%-10%, and potassium fertilizer 20%-30%. these ratios should be adjusted based on crop type, growth stage, and soil conditions.

2. Select Fertilizers: Choose appropriate compound fertilizers from the market, such as urea, diammonium phosphate, or potassium chloride. Consider factors like purity, nutrient content, and solubility. Opt for reputable brands to ensure effectiveness.

3. Weigh the Fertilizers: Use an electronic scale or manual balance to accurately measure the required amounts of each fertilizer. For example, if 20% nitrogen is needed, weigh out 20 grams of nitrogen fertilizer.

4. Dissolve the Fertilizers: Place the weighed fertilizers into a container and add an appropriate amount of water (usually 1-2 times the weight of the fertilizer). Stir with a glass rod or spoon until fully dissolved. If the fertilizer contains crystalline water, dissolve it first before mixing with water.

5. Adjust Soil pH: Some fertilizers may affect soil acidity or alkalinity. Adjust the soil pH before application using materials like lime or ferrous sulfate.

6. Apply the Fertilizer: Evenly spread the dissolved fertilizer onto the soil surface or into furrows, then deeply till the soil to ensure thorough mixing. Avoid direct contact with plant roots to prevent root burn.

7. Timing of Application: Determine the timing based on crop growth stages and weather conditions. Topdressing is typically done during active growth phases, while base fertilizers should be applied before planting.

8. Application Rate: The amount of fertilizer depends on crop condition and soil fertility. A general guideline is 10-20 kg per mu (0.066 hectares), but adjust according to specific needs.

9. Precautions:

   • Avoid over-fertilization to prevent soil salinization and nutrient imbalance.
   • Do not apply fertilizer during rainy days to avoid runoff.
   • Water the soil promptly after application to enhance nutrient absorption.
   • Monitor crop growth and soil fertility regularly to adjust strategies as needed.

By following these steps, you can formulate NPK compound fertilizer tailored to crop needs. Note that different crops may require varying NPK ratios, so adjustments are essential. Proper use of compound fertilizers improves crop yield, quality, and contributes to sustainable agricultural development.
