Abstrak This study aims to determine the vertical distribution of soil phosphorus (P) nutrients in three different land uses so that it can be known at how deep the P elements accumulate in the soil and how the solution to utilize the phosphorus (P) nutrients accumulated in the soil. This research was carried out in Toribulu Village, Dusun IV Padang, Toribulu District, Parigi Moutong Regency and Analysis of Soil Chemical Properties will be carried out in the Soil Science Unit Laboratory, Faculty of Agriculture, Tadulako University. This research was conducted from April to May 2019. Data analysis used descriptive exploratory methods, namely describing each of the soil's chemical nature variables based on the results of the laboratory and field analysis and supported by rainfall data for the last five years in the area. Vertical distribution on three different land uses shows the highest P-Total distribution in cocoa land (36.38 mg / 100g-1), Deep Coconut (35.59 mg / 100g-1) and Tegalan (34.93 mg / 100gr-1) each one into 0 cm or top layer. While the lowest P-Total in cocoa fields (15.43 mg / 100g-1), Deep Coconut (20.49 mg / 100g-1) and dry fields (25.30 mg / 100g-1) each at a depth of 100 cm . The vertical distribution of the P-Available shows the highest values in the cocoa field (12.37 ppm), Kelapa Dalam (11.97 ppm) and Tegalan (11.27 ppm) each at a depth of 0 cm. While the lowest value of P-Available in cocoa land (0.71 ppm), Kelapa Dalam (2.52 ppm) and Tegalan (0.24 ppm) each at a depth of 100 cm, with very low to low criteria.
