摘要: Relationships between soil physicochemical characteristics and microbial C, N, P in Indian dry tropical ecosystems are discussed. The major ecosystem studies were on forest, savanna, cropped fields, mine spoils. highest levels recorded from the mixed forest lowest 5-year-old spoil. Across sites, C ranged 226 to 643 μg g-1, N 19 71 9 28 g-1 soil. proportion of organic contained biomass 2.2 5.0%. C: ratio these soils 7.4. 13.1 16.6 30.6. concentrations correlated with several properties among themselves. properties, various linear combinations, explained 90–99% variability nutrients. Grazing savanna had some effect level biomass, as spoil aged, also increased.
