Toward the use of organic matter as an alternative to chemical fertilizers which have recently increased in price, we investigated the root production and mortality of paddy rice using organic matter and crop production and carbon sequestration in relation to the dynamics. In the results, the production and mortality of root of rice using organic fertilizer were more than using chemical fertilizer. Using RothC models with our data, the evaluation of soil carbon sequestration was changed depending on these differences in roots. Our results suggests the effects of root dynamics is greater than the previous evaluations.

针对近年来价格上涨的化肥替代品--有机质的使用，研究了有机质对水稻根系生产和死亡率的影响，以及有机质与作物生产和碳汇的动态关系。结果表明，施用有机肥的水稻根系产量和死亡率均高于施用化肥。使用RothC模型与我们的数据，土壤固碳的评价根据这些差异的根而改变。我们的研究结果表明，根动力学的影响是大于以前的评估。
