Organic Fertilizers
Organic fertilizers are made from plant, animal, or mineral sources. They include compost, manure, bone meal, fish emulsion, green manure, and biofertilizers. Unlike synthetic fertilizers, they improve soil health over time by increasing organic matter and microbial diversity.
Benefits of Organic Fertilizers
- Sustainable: Reduces dependency on chemical inputs
- Soil Health: Enhances microbial life and organic carbon
- Slow Release: Minimizes leaching and nutrient burn
- Eco-Friendly: Lower risk of groundwater contamination
- Improves Crop Quality: Enhances taste, shelf life, and nutritional value
