Biochemical contributions to soil aggregation under Miscanthus × giganteus: Iowa multi-site dataset

The data provided include results from a comparative study evaluating the impact of Miscanthus × giganteus (miscanthus), maize, and turfgrass on soil aggregation and associated biochemical pools across three Iowa field sites. The dataset includes aggregate stability metrics (water-stable aggregates, WSA; mean-weighted diameter, MWD), microbial biomass carbon (MBC), extracellular polysaccharides (EPS), total carbohydrate monomers, the galactose + mannose : arabinose + xylose (GM:AX) ratio, and amino compounds. All data are provided as replicate-level measurements, organized by site, treatment, and replicate, with processed summary tables in CSV (.csv) to support reproducibility and downstream analysis.

本数据集包含一项对比研究的实测结果，该研究针对艾奥瓦州3处野外试验点，评估了巨芒草（Miscanthus × giganteus）、玉米与草坪草对土壤团聚体及相关生物化学组分池的影响。数据集涵盖团聚体稳定性相关指标，包括水稳性团聚体（WSA）、平均重量直径（MWD）、微生物生物量碳（MBC）、胞外多糖（EPS）、总碳水化合物单体、半乳糖+甘露糖：阿拉伯糖+木糖（GM:AX）比值以及氨基化合物。所有数据均以重复水平的测量值形式呈现，按试验点、处理组与重复样本进行分类整理，并附带经过处理的汇总表格，以CSV（.csv）格式存储，可为研究可重复性保障及下游分析提供支持。
