Pengaruh Penggunaan Lahan dan Posisi Lereng Kandungan C-Organik dan Beberapa Sifat Fisik Tanah Inceptisols Jatinangor, Jawa Barat

Abstrak

The aims of this study is determine the effect of land use and slope position on the organic C and some physical soil in the Jatinangor area, West Java. The study was conducted in April 2018 until October 2018. The study used a Randomized Block Design (RBD) factorial pattern. The first factor is land use (forest and moor) and the second factor is the position of the slope (upper, middle and lower). The sampling method uses survey, comparative and descriptive methods through a physiographic approach (physiography approach) freely, namely the survey method based on the physiographic appearance of the land and soil sampling is carried out by transect on the same slope without taking into account the distance between observation points. Observations made were C-organic, Texture, Content weight and Permeability. The results showed that land use (forest and moor) and slope position (middle and lower top) affected the organic c content and physical properties of the soil such as texture (sand, dust and clay), fill weight and permeability on Inceptisol Jatinangor soil. The use of upland land with lower slope position has the best influence on the c-organic content, texture, weight and soil permeability compared to land use and other slope positions.
