Manure: Animal manure, such as a cow or chicken manure, is a common organic fertilizer that provides nitrogen, phosphorus, and potassium to plants.
Compost: Compost is made from decomposed plant and animal materials and is rich in nutrients such as nitrogen, phosphorus, and potassium.
Fish emulsion: Fish emulsion is made from fish waste and is a good source of nitrogen and other nutrients.
Bone meal: Bone meal is made from ground-up animal bones and is high in phosphorus.
Examples of inorganic fertilizers include:
Urea: Urea is a common nitrogen fertilizer that is made from synthetic materials.
Ammonium nitrate: Ammonium nitrate is a high-nitrogen fertilizer that is made from synthetic materials.
Triple superphosphate: Triple superphosphate is a phosphorus fertilizer that is made from phosphate rock and sulfuric acid.
Potassium chloride: Potassium chloride is a potassium fertilizer that is made from mined minerals.
Both organic and inorganic fertilizers can be used to provide nutrients to plants, but they differ in their nutrient content and environmental impacts. Organic fertilizers are often slower-acting but can improve soil health and fertility over time, while inorganic fertilizers are more quickly available to plants but can contribute to soil acidity and other environmental problems if used in excess.
