Abstract

                This research was purposed to develop the research participation with farmers concerning the process of aerated static pile composting system from mixed water hyacinth and cow dung at HubMaKhum community. The result reveled that the production cost was 1560 baht/ton, production time was 60 days (6 times/year). The amount of nutritional composition was N 2%, P₂O₅ 1.88% and K₂O 1.41%. The compost had 44.92% of moisture content, and 17.06% of organic matter. For the other character such as pH was 7.2, C/N ratio was 4.96 and 2.1 dS/m of electric conductivity and no contamination from other materials. For standard evaluation it ha s 82 points, by the quality and standard of land development department (≥ 80 for standard). The amount of heavy metal was lower than the organic fertilizer standard of department of agriculture. However the used of 400 – 600 kg/rai of compost mixed with 20 -25 kg/rai of chemical fertilizer (urea 46-0-0) for planting baby corn and tien corn. The productions of both un-husked ears were not significantly different from chemical fertilizer only with 40-50 kg/rai. But the amount of compost mixed chemical were more than chemical fertilizer only. It can be concluded that this compost had a good quality and meet standard requirement. It was suitable for soil improvement and usefully with chemical fertilizer for planting and environmental friendly materials.
