Why Not to Use Chicken Manure on Root Vegetables

Why Not to Use Chicken Manure on Root Vegetables

Fresh chicken manure is extremely high in nitrogen, which promotes leafy growth at the expense of root development. It can also burn tender roots. Aged manure (3+ months) is safer for other crops, but root vegetables need a different nutrient balance.

Best Fertilizer for Root Crops

• Use a fertilizer high in potassium (the third number), such as a 5-10-20 ratio.
• Avoid high-nitrogen fertilizers (first number).
• Potassium supports strong root growth and overall plant health.

Save the chicken manure for leafy greens or compost it fully before using near root crops.
