摘要: Abstract The soil physicochemical characteristics and amounts of microbial biomass C, N, S in 19 soils (10 grassland, 2 forest, 7 arable soils) were investigated to clarify the status granitic regosols Japan, order determine relationships between other estimate approximately annual Sand N flux through biomass. Across sites, amount C ranged from 46 1,054, 6 158, 0.81 13.44 mg kg-1 with mean values 438.8, 85.8, 6.15 soil, respectively. Microbial Nand accounted for 3.4–7.7% 1.1–4.0% total S, C: : ratios varied considerably across sites 3.0–10.4, 32.5–87.7, 5.0–18.8, was linearly related N. regression 96.6% 92.9% variance data. Th...
