Marco Rodel J. Aragon and Victor B. Asio ABSTRACT Rewetting of soils may cause an increase in phosphorus solubilization and nitrogen mineralization resulting in the release of bioavailable phosphates and nitrate which are vital for crop growth but are also associated with eutrophication of surface waters. The study was conducted to evaluate P solubilization and …
