Ammonia volatilization loss was measured using modified force-draft technique to evaluate its effect via application of palm oil mill effluent (POME). Three type of BRIS soils; Melawi, Rudua, and Rhu Tapai were used under controlled laboratory condition with soil moisture maintained at 40 %. Application of typical urea and three (3) types of formulated control release urea fertilizers; Meister-20, CR Duration type V, and CDU Uber-10 at the rate of 400 µg/g were used en masse. Whilst, the application of POME was set at 100 kg/ha of dried POME. Ammonia volatilization loss was recorded on daily basis for a period of two weeks. Results indicated that, the combination of POME and urea shows the best reduction of NH 3 at 83.6 % compared to without POME inclusions. The CRU fertilizers and incorporation of soil with POME in general shows best effect in reducing NH 3 loss.
