      Gypsum Amendment Reduces Redox-Induced Phosphorous Release from Freshly Manured, Flooded Soils to Floodwater 

      Dharmakeerthi, Randombage S.; Kumaragamage, Darshani; Indraratne, Srimathie P.; Goltz, Doug (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 

      Kumaragamage, Darshani; Amarawansha, Geethani S.; Indraratne, Srimathie P.; Jayarathne, Kumudu; Flaten, Donald N.; Zvomuya, Francis; Akinremi, Olalekan O. (American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2019-11-01)
      Phosphorus (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 

      Dharmakeerthi, R. S.; Kumaragamage, D.; Goltz, D.; Indraratne, S. P. (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 

      Kumaragamage, Darshani; Concepcion, Angela; Gregory, Carolyn; Goltz, Doug; Indraratne, Srimathie; Amarawansh, Geethani (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 ...
