Poultry litter is a multi-nutrient fertilizer that can only be applied to no-till cotton by broadcasting on the soil surface without incorporation. This practice leaves some fraction of litter-derived N vulnerable to volatilization loss. Research wasconducted in north MS in 2003 to estimate the magnitude of litter benefit loss due to lack of incorporation of surface-applied broiler litter. The results showed that applying litter on the soil surface without incorporation is an effective method of fertilizing no-till cotton. However, nearly 10% of the litter benefit is lost due to lack of incorporation, which implies an upward adjustment by ≈10% of the litter rate is necessary when litter is used as the primary fertilizer of no-till cotton.
