Study on physical properties of rangeland at some slope levels in Nagari Aie Dingin, District of Lembah Gumanti, Solok Regency

Abstract A field study was carried out in Nagari Aie Dingin, Lembah Gumanti District, Solok Regency. This research aimed to examine the physical properties of Inceptisols at several slope levels location. The soil samples were taken by purposive sampling based (slightly steep [8-15%], moderately [15-25%], [25-45%], and very [>45%]), coffee (25-45%) for two depths (0-30 cm 30-60 cm). results showed that area had silt loam, silty clay texture. By increasing level (from 8-15% >45%), organic matter content tended decrease 5.74 2.58), bulk density increased 0.58 0.79 g/cm3), total porosity decreased 71.20 62.80), permeability rate 9.47 4.01), both Meanwhile, aggregate stability index considered moderate. Compared land under cultivation, rangeland still lower than plantation. There a negative correlation between SOM BD (r cm) = -0.85 r (30-60 -0.69) positive STP 0.95, 0.80) 0.37, 0.85). Based on fact, it is suggested apply appropriate cultivation techniques provide suitable input improving properties.
