Sarawak has the largest area of oil palm on deep peat in Malaysia. Peat is a fundamentally different growing medium, and a programme written for mineral soil will underperform on it — sometimes badly.
A very large share of Sarawak’s planted area sits on deep peat, with acid sulphate soils in parts of the coastal plain. Peat is almost entirely organic, extremely acidic, low in mineral nutrients — particularly copper, zinc and boron — and subject to subsidence as it oxidises.
The agronomic priorities invert compared with mineral soil. Adding bulk organic matter is not the constraint; the constraints are pH, micronutrient supply, water table management and physical stability. Biological activity and nutrient cycling still matter, but the limiting factors sit elsewhere.
Sarawak receives high rainfall year-round, intensifying during the northeast monsoon from roughly November to February. Combined with peat hydrology, water table management is a permanent operational concern rather than a seasonal one.
