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 ...
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 ...
Mobility of arsenic and vanadium in waterlogged calcareous soils due to addition of zeolite and manganese oxide amendments
Addition of manganese(IV) oxides (MnO2) and zeolite can affect the mobility of As and V in soils due to geochemical changes that have not been studied well in calcareous, flooded soils. This study evaluated the mobility ...
