Soil Management Impact on Soil Characteristics (Physiques) and Erosion on Hapludalfs Bogor

Abraham Suriadikusumah, Sidik Permana, Ika Mertikawati

Abstract: The experiment was conducted to find out the effect of terrace types and elephant grass (Pennisetum purpureum) on erosion; aggregate stability; and permeability of Typic Hapludalfs. The experiment was done in the rainy season in Sukamulya village; Sukamakmur; Bogor; West Java with the altitude of 800 m above sea level and slope of 30 %. Randomized block design was used in this experiment; consist of 5 treatments and 3 replications. Treatments were: without terrace and without grass (T0) as a control; dike terrace without grass (T1) ; dike terrace with grass (T2) ; bench terrace without grass (T3) ; and bench terrace with grass (T4). The results Showed that; there were highly significant difference effect of terrace types and grass (Pennisetum purpureum) on erosion; soil aggregate stability; and soil permeability. The treatment of the bench terrace with elephant grass (T4) gave the lightest eroded soil of 6.698 t ha-1. The decreasing value on aggregate soil stability and soil permeability were significantly affected by increasing erosion. These relationships were very closed; showed on the coefficients of regression determination of 96 % and 97 % respectively. Meanwhile the increasing of rainfall followed significantly by increasing of erosion; with a regression determination coefficient of 99 %. The result of this study; showed that; there were significantly correlated between erosion with soil aggregate stability; soil permeability; and rainfall.
