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 ... -
Mobility of arsenic and vanadium in waterlogged calcareous soils due to addition of zeolite and manganese oxide amendments
Indraratne, Srimathie P.; Attanayake, Chammi P.; Kumaragamage, Darshani; Amarawansha, Geethani; Goltz, Douglas M.; Applin, Daniel M. (Wiley, 2023-01-17)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 ...
