Evaluating Chicken Mash as an Organic Fertilizer

Ingredient Analysis

Chicken mash (cracked corn, soybean meal, wheat bran, calcium carbonate, molasses, alfalfa, grit, oyster shell, phosphate, canola oil, salt) is a complete feed, not a fertilizer.

Concerns

• Unknown NPK: Must calculate or test.
• Salt: Can harm sensitive plants and soil structure.
• Oil: May create hydrophobic layers.
• Calcium: High levels raise pH, potentially causing nutrient lockout.

Recommendation

If determined to try, buy a small amount, test on a trial bed, and monitor plant response. Better: use dedicated organic fertilizers (alfalfa meal, soybean meal, kelp) with known analyses.
