Biography
Trenton L Roberts, Department of Crop, Hydrogen sulfide (H2S) toxicity is a poorly understood physiological disorder that occurs under anaerobic conditions and can cause substantial yield loss in rice (Oryza sativa L.). Though the reduction of sulfate (SO42-) to H2S is the causes of toxicity, there are many factors that influence the extent to which this occurs.

Soil Physical and Chemical Characteristics Influencing Hydrogen Sulfide Toxicity
Author(s): Julia M Fryer, Trenton L Roberts*, Yeshi Wamishe, Jarrod T Hardke and David M Miller
Hydrogen sulfide (H2S) toxicity is a poorly understood physiological disorder that occurs under anaerobic conditions and can cause substantial yield loss in rice (Oryza sativa L.). Though the reduction of sulfate (SO42-) to H2S is the causes of toxicity, there are many factors that influence the extent to which this occurs. Two greenhouse studies were designed to investigate the chemical and physical characteristics of four soils in Arkansas where this disorder occurs regularly (H and HR-W), sometimes occurs (HR-E), and has never been reported (PTRS). The three soils that have had this disorder (H, HR-W, and HR-E) contained approximately 30% more silt than PTRS. Mehlich 3 extractable SO42- and Fe concentrations w... view more»
