SIFAT FISIK DAN KIMIA TANAH PADA BEBERAPA PENGGUNAAN LAHAN DI SUB DAS MEKO KECAMATAN PAMONA BARAT KABUPATEN POSO

Soil physical properties are environmental factors that greatly affect the availability of water, air and soil. The chemical properties of the soil, which play a role in the nature, characteristics of the soil and soil fertility, the chemical properties of the soil, namely soil pH, NPK, cation exchange capacity (CEC), and C-organic. This study used a survey method. Soil sampling was then analyzed in the soil science laboratory. The physical properties of the soil in paddy fields and shrubs have dusty clay properties, dry land agriculture has loamy clay properties and large shrubs have clay properties. . As for the chemical properties of the soil, namely pH in some land uses, the criteria are slightly acidic with a value of 6.38, shrubs 6.22, rice fields 5.50 and dry land agriculture 4.84. For c-Organic, the lowest was 2.28% and the highest was 3.78%. N-total ranges from 0.16% the lowest and the highest with a value of 0.30. For phosphorus (p) ranged between 52.92 the lowest value and the highest value 54.51. For Potassium (K) the highest value is 38.54 and the lowest is 10.82. The CEC value ranges from 38.54 for the highest value and the lowest value is 29.51
