Role of Redox Reactions and AI-Driven Approaches in Enhancing Nutrient Availability for Plants

Empirical studies have shown that environmental variability in the field remains uncontrolled in certain cases, with research often conducted at a limited number of agricultural sites. Direct measurements of redox potential in soils have been reported, yet quantifying rapid changes in this variable across microsites proves inaccessible in situ. Existing measurements of redox potential also fail to account for variability in the identity of reduced or oxidized compounds. Additionally, methodological constraints and researcher bias, particularly in studies focusing on processes in reduced sediments, may impair interpretations of anabolic reactions resulting from oxidation.Case studies further indicate that the effects of redox potential on nitrification, net mineralization, or immobilization of other nutrients often remain unmeasured. As a result, increased denitrification might stimulate nitrification, reducing the effects of nitrogen immobilization due to increasing carbon storage in environments where reduction predominates.Given the absence of studies specifically exploring the balance between reduction and oxidation in relation to nutrient availability, assessing the magnitude and likelihood of methodological shortcomings based on prior field research remains challenging. Existing research serves as a foundation for understanding how this balance may significantly influence nutrient dynamics and availability at larger scales. Future studies manipulating redox potential in the field should consider factors that could disproportionately facilitate reductions before an eastward shift occurs in the balance between oxidation and reduction in response to organic matter addition. Addressing these gaps will enhance understanding of redox reactions and their potential role in stimulating denitrification and sulfide responses.
