บทคัดย่อ (EN): Increase in soil organic matter accumulation in a degraded tropical sandy soil can be achieved by application of organic residues with appropriate qualities (biochemical composition). However, the effect of allelopathic substances produced by some organic input such as tamarind leaves residue on underlying response of soil microbes remains scarce. To address this question, this study aims to investigate the preliminary effect of allelopathic substances in terms of natural allelopathic substances from tamarind leaves and commercial allelopathic substances (caffeic acid, tannic acid and gallic acid) on bacterial population from unamended soil, soil applied with long-term application of tamarind leaves residue and soil applied with long-term application of groundnut residue. Research finding showed that the appearance of 10% allelopathic substances extracted from tamarind leaves in unamended soil, soil applied with long-term application of tamarind leaves residue and soil applied with long-term application of groundnut residue were not significantly affecting bacterial population which suggested that allelopathic substances contain in tamarind leaves certainly not affect bacterial population with appropriated concentration and certain soil bacteria can transform the new chemicals into less toxic forms. Remarkably, some introduced allelopathic chemicals such as tannic acid had an effect on decreasing of the population of bacteria. Thus, prospective research should consider the effect of allelopathic chemicals, apart from studying microbial population, but also on microbial communities and activities.
