The objectives of this study were to analyze soil aggregation and associated soil organic carbon (SOC) under cup plant and maize in a field trial (sandy loam) and two farmers' fields (both silty loams) during the 2018 growing period. On the sandy loam, aggregation under the two crops did not differ despite higher bulk SOC under cup plant. At the silty loam sites, cup plant exhibited a 64% higher aggregate mean weight diameter than maize in spring and higher aggregate-associated SOC in autumn.

与玉米相比，多年生能源作物杯状植物的土壤聚集和聚集相关有机碳浓度

本研究的目的是在田间试验（砂质壤土）和两个农田（均为粉质壤土）中分析 2018 年生长期间杯形植物和玉米下的土壤团聚体和相关土壤有机碳 (SOC)。在砂质壤土上，尽管杯具下的松散 SOC 较高，但两种作物下的聚集没有差异。在粉质壤土场地，杯形植物在春季表现出比玉米高 64% 的团聚体平均重量直径和在秋季与团聚体相关的 SOC 高。
