Abstract
Escalating the land quality can be done by analyzing soil chemical properties which have a crucial role in plant growth and production. With chemical analysis of soil, it is expected to be able to respond appropriately in order to apply suitable steps taken in sustainable land management. The method used in this study was a field observation survey and soil sampling on agricultural lands in the Makbon district. The observed variables were pH H2O, Organic C, Total N, Available P, K2O, exchangeable cations, cation exchange capacity and saturation of alkaline. The results obtained in this study showed that the soil chemical characteristics on agricultural lands in several villages in Makbon District included- pH was acidic to slightly acidic, organic C was moderate to high, total N was low to moderate, available P was very low to low. While basic cations- Ca was high, Mg was medium to high, K was low to high, Na was very low to low, CEC categorized medium and KB was very low to very high.
