Soil chemical characteristic of secondary forest (Pangale) was pH (H2O) 4.78, C-organic 1.54 %, N-total 0.49 %, P-vailable (Bray I) 4.97 ppm, K-total 4.57 mg/100g dan CEC 8,46 cmol (+) kg-1. The soil chemical characteristic of  agroforestry land (Oma) was pH (H2O) 5.05, C-organic 1.39 %, N-total 0.13 %, P-available (Bray I) 5.35 ppm, K-total 3.73 mg/100g and CEC 8.93 cmol (+) kg-1.Keywords : Soil Chemical Characteristic, Land Use,  Lore Lindu National Park
