Research Abstract |
The main objectives of the present study were constructing and validating the elemental dynamics kinetic model that described the ecosystem processes for acquiring mineral resources by biosphere. The linear relationship was observed between the rates of net primary production and soil acidification. The alteration of these processes after human reclamation of forests for agricultural use was quantitatively described. The impact of soil acidity on the soil microbial processes was also quantitatively evaluated based on the two-step decomposition model including both solubilization and mineralization of polysaccharides and two-step metabolism by soil microorganisms in substrate utilization.
