Farmers can prevent pollution from agricultural fertilizer bags by using sustainable practices. They can opt for slow-release fertilizers that minimize runoff. Proper application rates and timing, based on soil tests, can reduce excess fertilizer that leaches into water systems. Farmers can also use precision agriculture techniques to apply fertilizers only where needed. Recycling or disposing of used bags properly and avoiding over-fertilization are also crucial. Integrating organic matter and crop rotation can enhance soil health, reducing the need for chemical fertilizers.
