Effect of different reclamation patterns on soil organic carbon distribution of aggregates in the topsoil of the Calamagrostis angustifolia wetland in Sanjiang Plain, China
Abstract:How reclamation of Calamagrostis angustifolia wetland for soybean and rice farming impacts the SOC distribution of aggregates in the topsoil was investigated. A declining trend of macro-aggregates (>0.25mm) but increasing of micro-aggregates of 0.053~0.25mm in the soybean field and 1mm and 0.053~0.25mm aggregates were lost more in soybean field than in paddy field, but opposite conclusion for paddy field>soybean field while the SOC storage of micro-aggregates (soybean field>paddy field. Compared with soybean field, paddy field contained slightly higher SOC but both the SOC storage of micro-aggregates (<0.25mm) in paddy field and its share in total soil SOC were lower. Therefore, after reclamation, soybean farming was more friendly for sustainable SOC residence in the soils than rice farming.
