Water cycling and balance estimations for three climatic zones in Malaysia were carried out using data from three trails. Results indicated that mean yearly evapotranspiration rates accounted for up to 61% of annual rainfall, while the balance was lost through surface runoff and leaching. Water partition studies based on destructive sampling indicated that annual water uptake by the oil palm is very small. An average of 0.24% of annual rainfall is stored within the oil palm vegetative matter, while an average of 0.04% is lost through fresh fruit bunch (FFB). Therefore, for every 1t of water taken up by the palm, 2.4 kg of dry matter is produced.
