| Abstrak Chemical properties of soil in rubber stands. The study was conducted in Polando Jaya Village, Central Sulawesi, the purpose of the study was to understand the chemical condition of the soil under rubber stands. The study was conducted for 2 months from April to July 2023, with soil sampling at peak and valley slopes through field surveys. Samples were taken from plots measuring 20m x 20m in each area, each plot having five composite sample points. Laboratory analysis measures soil pH, Nitrogen Carbon (N-total), Phosphorus (P-total), Organic Carbon (C-Organic), Potassium (K-available), and Cation Exchange Capacity (CEC). The analysis results showed that at peaks and valleys, soil pH was highly acidic (4.40 and 4.45 respectively), with high C-Organic (4.17% and 4.07%), medium N-total (0.28% and 0.27%), and low P-total (18.79 mg/100gr and 18.04 mg/100gr). However, the cation exchange capacity (CEC) is different, with those at the summit showing medium (20.38 cmol(+)kg-1) and those in the valley showing low (14.43 cmol(+)kg-1).
