Organic fertilizers like chicken, cow, and buffalo manure are natural substances used to enrich soil and promote plant growth. These fertilizers are rich in essential nutrients such as nitrogen, phosphorus, and potassium. Chicken manure is beneficial for leafy green growth, while cow and buffalo manure improve soil structure and nutrient retention. These organic fertilizers release nutrients slowly, enhance soil health, and reduce the risk of nutrient leaching. However, it is crucial to use them in moderation and follow recommended guidelines to avoid nutrient imbalances and environmental issues.
