    Cultivation of winter cover crop is strongly recommended for improving soil quality and carbon sequestration in mono rice cultivation system in Korea. Selection of appropriate cover crops requires an adequate knowledge of the quality and quantity of each plant biomass produced and its carbon sequestration potential. This study investigated the effect of four winter cover crops (barley, Chinese milk vetch, hairy vetch, rye) having different C/N ratio on plant above-ground and root biomass productivity and carbon sequestration in paddy soil before rice transplanting. Cover crops were seeded in the late October 2007 after rice harvesting on the dried soil condition and harvested the mid May of next year before flooding for rice transplanting. In comparison, the control treatment without cover crops was naturally covered by short awn [Alopecurus aequalis var. amurensis]. Above ground dry matter of planted cover crops increased by ca. 430 to 1500% compared to that of the control (0.98 Mg ha^-1), ran ... 전체 초록 보기
