Biogeochemistry of Trace Elements: Reactions in Soils, irrigation of upland soils. Reduction reactions and organic matter production in flooded soils results in the accumulation of Se, Mo, V, and U in these soils. Boron and As remain soluble under reducing conditions. Changing management to increase aerobic conditions in formerly flooded soils and pond sediments increases Se availability to biota.

Bacterial Reduction of Selenium,x potential and organic carbon content of the drainage water must be optimized. Amendments such as molasses, zero-valent iron, and redox mediators and microbial inoculates will significantly enhance the removal of selenium from saline drainage water.

At the same time, the remaining (concentrated) portion would have a significantly reduced volume, enabling discharge to a terminal evaporation pond or final management by other environmentally and economically feasible means(e.g., deep-well injection, processing with industrial thermal evaporators, etc.).

It continued to expand with favorable water rights and policies, advancements in irrigation technologies, and imported water supplies. The need of subsurface drainage was long understood but failed to materialize due to lack of collective actions. The salinity dra

The leaching process flushed out trace elements such as Se, B, As, and U contained in marine sediments from the Jurassic to Miocene periods that were deposited in the surface soil layer. Pumping of groundwater lying deep in confined aquifer resulted in severe land subsidence. Water made
