Outline of Final Research Achievements |
It was found that microorganisms preferentially expended resources in the form of phosphatase production rather than β-D-glucosidase production to acquire phosphorus in soils with low phosphorus availability. Specific microbial species might predominate for production of phosphatase in low phosphorus available soils. The ratio of acid or alkaline phosphatase to β-D-glucosidase activities would be useful for evaluating phosphorus availability in soils.
