Abstract—Applying animal-manure-based amelioration techniques to soil in an attempt to increase the soil's capacity to adsorb pesticide residues from excessive use in the recent past has been suggested. Since the clay content and mineral types in Inceptisol are insufficient to support the sorption of contaminants optimally, soil ameliorants are needed. Closed-house chicken litter is a common waste in the environment that has demonstrated potential for this role. This waste, which is produced in three to five tons every harvest (32 days) by a chicken farm with a cage capacity of 80000–100000 chickens, is a combination of sawdust from cage matting and chicken manure. Using the batch equilibrium adsorption method and the Freundlich and Langmuir equations, this study treated soil with closed-house chicken litter ameliorant at 40 tons/ha. It was discovered that adding closed-house chicken litter to the soil improved the soil's pH level, organic content, negative charge, and cation exchange capacity (CEC). Consequently, the soil's capacity for adsorption rose with the use of this ameliorant, with a distribution coefficient (Kd) value of 5.581 L g-1 (at a dimethoate concentration of 200 mg/L) and a Qmax of 769.23L/mg. The adsorption process tends to follow the isotherms for both the non-ameliorated and ameliorated treatments, suggesting that adsorption can occur physically and chemically.
