Short-term effects of microbial exopolysaccharides and chicken feather hydrolysate vs. long-term effects of plant-derived biochar on temperate, coarse-textured agricultural soils

Dataset (MS Excel file) provides information on microbial activity, available nutrient content, and soil properties analyzed during a laboratory experiment using soil additives in temperate agricultural soils. It includes measurements of microbial respiration, available carbon, nitrogen and phosphorus, pH, microbial biomass carbon (Cmic) and nitrogen (Nmic), and water holding capacity (WHC). The dataset also features detailed soil fraction analyses, including free particulate organic matter (fPOM), occluded particulate organic matter (oPOM) and mineral-associated organic matter (MAOM).
