How to adjust double roller press granulator fertilizers for different crop needs?

In farming, fertilizers made by double roller press granulators play a key role in crop growth. Since different crops have unique fertilizer requirements, proper adjustments are crucial.

1. Adjusting Nutrient Content

Understand crop needs: Crops require different nitrogen, phosphorus, and potassium (NPK) ratios. Leafy vegetables need more nitrogen, while root crops like potatoes crave extra potassium. Study each crop's needs to set proper nutrient ratios.

Change ingredient mix: Modify raw material proportions accordingly. Add more nitrogen sources for leafy greens, or boost potassium inputs for tuber crops.

2. Controlling Granule Size  

Match plant characteristics: Shallow-rooted plants absorb small granules better, while deep-rooted crops handle larger particles.

Tweak machine settings: Adjust double roller press granulators’ roller spacing and pressure to create optimal granule sizes. Closer rollers make smaller grains, wider settings produce bigger chunks.

3. Choosing Additives  

Add micronutrients: Specific crops need trace elements. Legumes require molybdenum-add ammonium molybdate to their fertilizer.

Include bio-agents: Add beneficial microbes like rhizobia for crops needing improved soil ecology. These bacteria help plants grow stronger.

4. Consider Growth Stages  

Phase-based adjustments: Crops need varying nutrients at different stages. Early growth demands more nitrogen, while flowering and fruiting phases require extra phosphorus and potassium. Time-release formulas can match these changing needs.

By customizing double roller press granulator fertilizers through these methods, people can better support each crop's specific requirements, boosting agricultural productivity effectively.
