I am broadly interested in C:N dynamics and management practices that promote long term soil health for sustained agronomic productivity. My research focuses on nitrogen availability in relationship to rice field management, specifically fallow and continuous flooding. Continuous flooding with winter straw decomposition can cause an accumulation of lignin-derived recalcitrant phenols that bind to mineral nitrogen in the humic faction, making applied nitrogen less available for crop uptake and causing yield losses. The research attempts to understand if increased nitrogen application are needed for continuous flooding to obtain optimal yields and quantify the degree of soil N immobilization caused by soil phenols. Additionally, I am also quantifying greenhouse gas emissions for the two management practices specific to this rice growing region of Sacramento Valley.
