Karakterisasi Fisik dan Kelembaban Tanah pada Berbagai Umur Reklamasi Lahan Bekas Tambang

Abstract

Mining activities cause uncovering of forest vegetation, decrease soil physical, chemical and biological characteristic so that causes land degradation. Land revegetation conducting to improve soil quality on mined land. The objective of research is reviewing influence of land revegetation against soil physical, chemical and dynamics of soil moisture content. Overall mined land has a klei texture, slightly acid soil reaction, high drainage pore and available water which moderate. The highest water content at the seventh day after rains in the forest that is equal to 29.81% on 30-50 cm soil depth. Soil moisture content was higher on lower layer because water content have not been absorbed by the roots or not been lost through evapotranspiration. Physical characteristic such as bulk density, porosity, permeability, infiltration, and soil chemical such as soil organic matter content and soil reaction have improved along with increased age of mined land reclamation.
