Impact of chemical fertilizer on soil fertility of oil palm plantations in relation to productivity and environment

Abstract Indonesia produces around 45 MT of CPO in 2020. It is predicted that the demand world palm oil will remain. Most plantations are grown on acidic soils with low fertility levels, such as Peat soils, Podzolic and Acid sulfate soils. The domestic phosphate Kalium fertilizer still fulfilled by importation. Production had depend this fertilizer. Various research results have found fertilizing using chemical anorganic fertilizers, especially Urea, TSP, KCl Kieserit, has produced fresh fruit bunches which quite high profitable. Fertilizing crops requires a very large cost 30% production costs. Currently, non-subsidized fertilizers rocketing, burdensome for farmers. Some indicate continuous use plants causes to land degradation. organic can improve sour less fertile land, increase weight number bunches. This paper aims examine impact production, well provide alternative sources mostly plantations.
