In association with pH, redox status of soil influences the solubility of
toxic metals, their stability and availability for various biochemical reactions under both aerobic and anaerobic conditions. Adverse redox potential (Eh) and pH can result in impoverished agricultural soils
(Delaune and Reddy, 2005), poor crop productivities and unbalanced
microbial ecological environments (Moore et al., 1990). The principle
management strategies established for sulfuric soils are to neutralize
