Particle-size fractions of soil organic carbon, microbial and mineral properties of Chernozem topsoil (0–10 cm) under different tillage systems in the Samara region of Russia (Original data)

Database includes measured data from 90 spatial sampling points on particle-size fractions of soil organic carbon (POM, MAOM), microbial properties (microbial biomass carbon, basal respiration), soil texture (silt, clay) and mineral composition of Chernozem topsoil (0–10 cm) under conventional tillage and no-tillage (Samara region, Russia). Date of soil sampling was October 2022.

本数据集涵盖俄罗斯萨马拉地区常规耕作与免耕两种耕作模式下，0–10 cm深度黑钙土（Chernozem）表层土壤的90个空间采样点的实测数据，检测指标包括土壤有机碳的粒级组分（颗粒态有机碳（Particulate Organic Matter, POM）、矿质结合态有机碳（Mineral-Associated Organic Matter, MAOM））、微生物特性（微生物生物量碳、基础呼吸速率）、土壤质地（粉粒、黏粒）及矿物组成。土壤采样时间为2022年10月。
