KEHILANGAN HARA AKIBAT EROSI (Studi Kasus di Tegakan Jati)
ABSTRACT: Teak Forest
Management in Indonesia began at period of Governance of Dutch Colonialism
in1860. After independence of Indonesia in 1945, teak forest was managed by Department
of Forestry and now was managed by Perum Perhutani. During that time have been applied by various approach of
management which relate to sustainable principles, but with existence of
ecosystem change, degradation of indication resource and productivity that teak
forest was not managed to sustainable principles. On the other side, commerce
of world wood claim the quality of wood coming from managed forest on
sustainability principles.
This research aim to studying erosion at various of trees age and
nutrient loss. Result of research showed that increasing of crop age was degrade
the erosion. Soil lose affects of erosion could bring consequence to losing of
soil nutrition. Mean losing of soil nutrition per hectare at various teak
plants age is : ( 13,8 - 74,3) kg of N; ( 8,7 - 36,2) kg of P; ( 7,2 - 35,2) kg
of K; ( 54,6 - 219,2) kg of Ca and ( 7,2 - 28,2) kg of Mg.
