Pengendalian Degradasi Tanah Gambut Pada Perkebunan Kelapa Sawit Dengan Aplikasi Mucuna Bracteata Di Area HGU Pt. Jatimjaya Perkasa
This study aims to determine the effectiveness of M. bracteata in controlling
peat soil degradation in oil palm plantations and to determine the effect of M.
bracteata age on controlling peat soil degradation in oil palm plantations. This
research was conducted using a survey method. The research location was
determined by using purposive sampling method. The type of location were
peatland planted with oil palm and applied M. bracteata and applied without M.
bracteata, which were 3, 4, and 5 years old. Each research location was repeated
for four replications. The parameters measured were soil physical properties
(volume weight) and soil chemical properties (pH, C-organic, N-total, Pavailable,
K-total, CaO, ash content, electrical conductivity, and redox potential).
Peatlands planted with oil palm and M. bracteata applied were able to
control the degradation of physical properties (water holding power and volume
weight) and chemical properties (ash content, N-total, P-available, K-total pH,
and CaO) compared to those not applied. M. bracteata. Peatlands planted with
oil palm and M. bracteata applied until the age of 3 years were able to control
chemical properties (available P and K-total), but the further increase in age of
M. bracteata (4 and 5 years) was no longer effective in controlling the
degradation of the peat soil properties . Peatlands planted with oil palm and M.
bracteata applied were able to control chemical properties (electrical
conductivity and ash content), until the age of 4 years, however, the further
increase in age of M. bracteata (5 years) was no longer effective in controlling
the degradation of the peat soil properties.
