Gypsum Amendment Reduces Redox-Induced Phosphorous Release from Freshly Manured, Flooded Soils to Floodwater
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America,2019-01-01)The effectiveness of gypsum in reducing runoff P losses from soils and the mechanisms responsible are well documented; however, gypsum amendment effects in reducing redox-induced P losses from flooded soils are less ... -
Degree of Phosphorus Saturation as a Predictor of Redox-Induced Phosphorus Release from Flooded Soils to Floodwater
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America,2019-11-01)磷(P)loss from soils is often enhanced under flooded, anaerobic conditions, increasing the risk of freshwater eutrophication. We aimed to develop a predictive tool to identify soils with greater P release potential ... -
Phosphorus Release from Unamended and Gypsum- or Biochar-Amended Soils under Simulated Snowmelt and Summer Flooding Conditions
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America,2020-03-30)Prolonged flooding changes the oxidation–reduction status of soils, often enhancing P release to overlying floodwater. We studied P release from unamended, gypsum-amended, and biochar-amended soils under simulated snowmelt ... -
Temperature and freezing effects on phosphorus release from soils to overlying floodwater under flooded-anaerobic conditions
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America,2020-03-30)Increased phosphorus (P) availability under flooded, anaerobic conditions may accelerate P loss from soils to water bodies. Existing knowledge on P release to floodwater from flooded soils is limited to summer conditions ...
