Rice variety KMP101 was treated with both organic and inorganic manure. The field and experimental studies were conducted, before applying organic and inorganic manures.The values obtained for available nitrogen, phosphorous and potassium were 360 kg/ha, 12 kg/ha and 166 kg/ha respectively. After treatment and harvest there was a gradual increase in available nitrogen, phosphorus and potassium ranging between 335-415, 14 -23 and 173- 235 kg/ha respectively among the treatments. Applying 15 t of vermicompost /ha and 10 t of vermicompost /ha and recommended dose of fertilizer showed a greater availability of nitrogen and phosphorus. It is revealed that after addition of organics into the soil year-wise, the soil became more stable. Also, the biological activity increased in the soil and was influenced to maintain the available nitrogen in the soil. Therefore, it is evident that vermicompost significantly increases the availability of available nutrients.
水稻品种KMP101用有机肥料和无机肥料进行了处理。在施用有机肥料和无机肥料之前，进行了田间和实验研究。有效氮、磷和钾的测定值分别为360千克/公顷、12千克/公顷和166千克/公顷。处理和收获后，各处理中有效氮、磷和钾逐渐增加，分别在335 - 415千克/公顷、14 - 23千克/公顷和173 - 235千克/公顷之间。每公顷施用15吨蚯蚓堆肥和每公顷施用10吨蚯蚓堆肥以及推荐剂量的肥料显示出更高的氮和磷有效性。结果表明，逐年向土壤中添加有机物后，土壤变得更加稳定。此外，土壤中的生物活性增加，并受到影响以维持土壤中的有效氮。因此，很明显蚯蚓堆肥显著提高了有效养分的有效性。
