Pengaruh Posisi Lereng terhadap Sifat Fisika dan Kimia Tanah pada Inceptisols di Jatinangor

Abstract

Slope held a vital role in soil formation and development through erosion, transportation, and deposition. The degree of the slope determines the flow rate and volume of surface water, while the slope position determines rate of the erosion. The research aimed to understand the impact of the slope position against physical (texture, Bulk Density, top soil thickness,) and chemical (pH, Organic carbon, and cation exchange capacity (CEC)) and the correlation between the top soil thickness to physical and soil chemical properties. The research was conducted in April to June 2016. The soil samples were taken from 15-25% slope and three positions: upper slope, middle slope and lower slope. Each slope was repeated 5 times, hence 15 spots of soil samples were obtained. This research used descriptive comparative method and stratified purpose sampling as the sampling technique.
