Status of Land Degradation for Biomass Production and Management Efforts inTabang Sub-districts, Kutai Kartanegara Regency

Abstract

The objectives of the study of land degradation status for biomass production are: (1) to collect data and information on initial soil conditions on land use for biomass production; (2) determine land degradation status for biomass production on land use for biomass production; and (3) mapping the status of land damage in Tabang sub-District, Kutai Kartanegara Regency. The research was carried out for 4 months, the research location was in Sidomulyo, Umaq Dian, Buluq Sen and Tukung Ritan Villages, Tabang sub-District, Kutai Kartanegara Regency. Research activities carried out include: preparation, field observations, soil sampling, soil sample preparation, soil analysis in the laboratory, data processing and interpretation, and reporting. The results showed that: (1) Land with not degradated status was found at four location i.e TB 2, TB 4, TB 10 and TB 11; (2) lightly degradated status occurred in 7 location i.e TB 1, TB 3, TB 5, TB 7, TB 8 dan TB 9; (3) land with moderate degradated status occurred at TB 6. Land degradation for biomass production mostly occurs in dryland caused by damage to the basic properties of the soil which includes soil pH, soil erosion, and bulk density.
