DAMPAK REKLAMASI LAHAN PASANG SURUT TYPE B TERHADAP KUALITAS LAHAN DAN POTENSI PRODUKSI TANAMAN SAWIT (Elaeis Guineensis. Jacq) Dl SCHEME KUALA CENAKU KABUPATEN INDRAGIRI HULU

Abstract

Type B tidal land in the District of Indragiri HuIu Regency Kuala Cenaku Reclaimed for cultivation of food crops in 1997 and 20% of the land is converted to oil palm plantations. Reclamation for the settings cause changes in pH of soil drainage and pyrite is oxidized, thus affecting nutrient availability to plants. It should be examined on land quality, crop nutrient uptake, oil production potential, the implementation of oil palm cultivation technology and its relation to social economic and farming system analysis in order to determine the impact of reclamation and the ability of communities in landmanagement. The research was conducted through a survey approach, purposively sampling random sampling and by selecting a planting site that has been producing oil with a maximum of I0 years of age. The results showed that soil texture component is dust> 70%, clay 21-28%, and sand <3%. Leaching and loss of land caused a layer of peat and organic matter in the soil surface decreased. Soil water content and bulk density is still on the threshold of adequate. Based on the content of base cations, it include in Zone II land and the influence of sea water with fresh water are balance. The level of soil fertility is low to moderate deficiency of macro element and non-visible symptoms of excess and deficiency of micro elements. Production of 23% -44% of potential oil production BPKS. Implementation of the cultivation technology of 90% in the-medium category, which examined social factors are not dominant in influencing the implementation. It is expected that the role of farmers to maintain channels and building floodgates, technical application specific culture through the study of fertilizer application efficiency,physical improvements and maintain the sustainability of soil fertility and crop farm with-multtple cropping pattern.
