Pengaruh Topografi Terhadap Beberapa Sifat Kimia Tanah Pada Perkebunan Kopi Arabika Rakyat Di Desa SaniK Kecamatan Malimbong-Balepe'Kabupaten Tana Toraja

This study aims to determine the influence of topography on several soil chemical properties in the area of folk arabica coffee plantations in Sanik Village, Malimbong Village – Balepe' Tana Toraja Regency. This research was carried out in the arabica coffee plantation area of the community in Sanik Village, Malimbong District – Balepe' Tana Toraja Regency. The research method carried out is a group randomized design method (RAL) consisting of 4 treatments, which are examples of soils that are in different slope positions, namely; The peak (A), Middle Slope (B), Foot Slope (C) and about 20 meters from the foot of the slope (D) are each repeated 4 times. The observed parameters are C-Organic, N, P, and KTK levels. If there is a real different treatment, it is continued with the BNJ 5% test. The results showed that the influence of topography in Sanik Village affected some of the chemical properties of the soil consisting of C-Organic soil at the foot of the slope and at a distance of 20 m parallel foot higher slopes with a range of values of 4.62% - 5.94% than at the top of the slope and middle of the slope. Similarly, at the level of N-Total, P- Total and KTK The soil decreased at the top of the slope and the middle of the slope but at the foot of the slope and 20 m parallel to the foot of the slope experienced an increase.
Keywords : Topography, C-Organic, N,P and Cation Exchange Capacity (KTK) of The Soils.
