KAJIAN TINGKAT KESUBURAN TANAH PADA HUTAN LINDUNG GUNUNG SEBATUNG DI KABUPATEN KOTABARU KALIMANTAN SELATAN
Abstract: Soil fertility is
the potential for soil to provide nutrients in sufficient quantities in a form
that is available and balanced to ensure maximum plant growth. Given the size
of Mount Sebatung function of protected forests and land degradation processes
that continue to occur, then in the framework of this area of land conservation
efforts need to be supported by data information, such as soil fertility
status. Accordingly, the level of soil fertility research in the protected
forest areas needs to be done. From the results of this study is expected to
give consideration in land conservation efforts being undertaken by relevant agencies.
The method used for soil sampling by purposive sampling on 4 observation sites,
namely under forest stands have 2 locations; under the stands of fruit orchards
and shrubs each 1 observation location. Intact soil samples taken using the
ring samples, while for the disturbed soil is done by the composite. The
results showed the level of soil fertility is physically in protected forests
of Mount Sebatung generally relatively high (medium). Slope factor (the hilly
topography) and soil depth is relatively shallow solum limiting factor in plant
growth. While the chemical status of soil fertility, especially under forest
stands are relatively higher compared with soil under stands of fruit orchards
and shrubs. The low pH of the soil becomes a limiting factor for the
availability of soil nutrients, although the contribution of organic material
from vegetation above it is quite high.
