| Abstract | Rubber tree (Hevea brasilliensis Muell.) is one of economic crops of Thailand and main production is in the southern region. Nowadays the plantation areas are expanded to other parts of the country because of its high price and continuous harvesting along the year. Soil under rubber tree have developed under tropical climate which their characteris?tics are acid, low fertility and risk of degradation especially in case of unappropriate management. Most of plant nutrients lose from plantation area by crop removal both from latex and from timber production. However, some part of plant nutrients still recycle in plantation area by annually litter falling. Chemical fertilizer this recommended for immature phase of the old region is 20-8-20 and 20-10-12 of the new region. Whereas 30-5-18 is recommended for tapping phase. Legume intercropping can reduce chemical fertilizer application and prevent soil erosion. Fertilizer application according to soil and plant nutrient status seem like the efficiency way, but still impractical for the small holder farmers. Organic fertilizer is also important for improving soil physical properties. However integrated management for sustainable production of rubber plantation should be further investigated. |
