Chicken manure is the feces of chickens used as an organic fertilizer, especially for soil low in nitrogen.[1] Of all animal manures, it has the highest amount of nitrogen, phosphorus, and potassium.[2] Chicken manure is sometimes pelletized for use as a fertilizer, and this product may have additional phosphorus, potassium or nitrogen added.[3] Optimal storage conditions for chicken manure include keeping it in a covered area and retaining its liquid, because a significant amount of nitrogen exists in the urine.[4]
Fresh chicken manure contains 0.5%[5] to 0.9% nitrogen,[6] 0.4%[4] to 0.5% phosphorus,[5] and 1.2% to 1.7 %potassium.[5] One chicken produces approximately 8–11 pounds of manure monthly.[6] Chicken manure can be used to create homemade plant fertilizer.[6]
Oyster shells are useful for your garden. Their calcium content helps to balance soil pH levels, improves nitrate uptake, aids enzyme formation and strengthens plant cell walls
Leaves are a significant source of nutrients such as Carbon, Nitrogen, Phosphorous, and Potassium.
