| Abstrak This research was carried out from July to September 2023 at two locations of teak stands, each 7 and 10 years old, in Towera Village, Siniu District, Parigi Moutong Regency. This research uses a field survey method to determine the research location. Soil sampling was carried out deliberately (purposive sampling), namely the sampling locations were located at 2 different teak stand locations. At each location, 2 plots measuring 20m x 20 m were created. Each plot has 5 diagonal soil sampling points. The soil samples taken were incomplete soil samples. Soil samples were taken under the stands at a depth of 0-30 cm. At each point a 1kg soil sample was taken and then composited. After being composited, 1kg was taken for analysis purposes. Each location contains 1 sample so there are a total of 2 samples for laboratory analysis purposes. Incomplete soil sampling is used to analyze soil pH. Nitrogen (N-total), Phosphorus (P-total), C-organic, and cation exchange capacity (CEC). The research results show that the soil chemical conditions in 7 year old teak stands have a pH (H2O) value of 4.31 (acid), C-Organic 2.90% (medium), N-Total content 0.15% (medium), ( CEC 24.3 cmol(+)kg-1 (medium), and Phosphorus 27.4% mg/100gr (medium). Meanwhile, 10 year old teak stands have pH (H2O) 5.17 (slightly acid), C-Organic. 3.60% (very high), N-Total content 0.17% (medium), CEC 22.1 cmol(+)kg-1 (medium), and phosphorus 44.5% mg/100gr (high). |
