Distribution and acceptance of phosphate fertilizers: a Malaysian experience

Chew K.L., . (1992) Distribution and acceptance of phosphate fertilizers: a Malaysian experience. [Proceedings Paper]

Jordan Morocco and China are looked upon as sources for natural rock phosphates following the closure of the Christmas Island mining operations towards the end of 1987. The Jordanian and Moroccan rock phosphates are now widely accepted as suitable alternative sources to CIRP. Of late China rock has become a popular source with their improved handling transporting and shipping arrangements. There are a number of parties now involved in the distribution of phosphate rocks. These phosphate rocks are either used as a straight fertilizer or in mixtures and in the manufacturing of NPK granular fertilizers. It is appropriate to mention here the availability of a high reactive rock phosphate from North Carolina NCRP known commercially as FASPHOS. This source is just as effective as the water soluble sources such as TSP and DAP in acidic soils. With the addition of this range the available rock phosphate sources should adequately cover the P requirements for the variety of crops grown in Malaysia. However the scope of this paper covers only the usage and agronomic benefits of these phosphates in the more important commercial plantation crops namely rubber oil palm and cocoa. The general usage and agronomic benefits of these phosphates are highlighted to cover all aspects of fertilizer management at nursery stage and during planting up to the end of the economic life span of the crops

Abstract

Jordan Morocco and China are looked upon as sources for natural rock phosphates following the closure of the Christmas Island mining operations towards the end of 1987. The Jordanian and Moroccan rock phosphates are now widely accepted as suitable alternative sources to CIRP. Of late China rock has become a popular source with their improved handling transporting and shipping arrangements. There are a number of parties now involved in the distribution of phosphate rocks. These phosphate rocks are either used as a straight fertilizer or in mixtures and in the manufacturing of NPK granular fertilizers. It is appropriate to mention here the availability of a high reactive rock phosphate from North Carolina NCRP known commercially as FASPHOS. This source is just as effective as the water soluble sources such as TSP and DAP in acidic soils. With the addition of this range the available rock phosphate sources should adequately cover the P requirements for the variety of crops grown in Malaysia. However the scope of this paper covers only the usage and agronomic benefits of these phosphates in the more important commercial plantation crops namely rubber oil palm and cocoa. The general usage and agronomic benefits of these phosphates are highlighted to cover all aspects of fertilizer management at nursery stage and during planting up to the end of the economic life span of the crops
