For good oil palm growth and production, heavy fertilization is required especially with nitrogen (N). Based on the current area under oil palm, it is estimated that the N fertilizer requirement exceeds three million tonnes N a year. Currently, urea is mostly used in compound fertilizers for oil palm. Urea has the added advantage of high […]

Malaysian soils, like most tropical soils, are highly weathered, acidic and inherently low in phosphorus (P) but with high P-fi xing capacities. High rates of P fertilizers are required to overcome the P-fi xation, mainly due to high Al and Fe oxides and hydroxides in the clay fraction (Ng, 1986). P is one of the major […]

The MPOB agronomic research team critically analysed NPK fertilizer combinations, then verified them in trials conducted from 1990 on wards in order to formulate a fertilizer with optimum balanced nutrients ratio for maximum yield of oil palm (Tarmizi et al., 2003). Main Research: Ahmad Tarmizi Mohammed 

Peat (with a total national area of approximately 2.6 million hectares) is a problem soil (Mutalib et al., 1991). The inherent physical and chemical properties of peat make its development for oil palm cultivation diffi cult and costly. Low bulk density, high water table and subsidence are among the major physical properties of peat that need […]
