Reclamation of Acid Soils

RECLAMATION OF SOME SODlC SOILS BY THE HIGH SALT WATER DILUTION METHOD

, Abstract Results of the laboratory reclamation of four sodic soils by the high salt water dilution method are reported. The exchangeable sodium percentage (ESP) of all soils was decreased by leaching with solutions of decreasing sodium but constant calcium concentration. Although a final leaching with water of low electrolyte concentration (EC,, < 100 micromhos/cm) did not produce a rapid dec...

Effect of Byproducts of Flue Gas Desulfurization on the Soluble Salts Composition and Chemical Properties of Sodic Soils

The byproducts of flue gas desulfurization (BFGD) are a useful external source of Ca(2+) for the reclamation of sodic soils because they are comparatively cheap, generally available and have high gypsum content. The ion solution composition of sodic soils also plays an important role in the reclamation process. The effect of BFGD on the soluble salts composition and chemical properties of sodic...

Organochlorine pesticides (OCPs) in wetland soils under different land uses along a 100-year chronosequence of reclamation in a Chinese estuary.

Soil profiles were collected at a depth of 30 cm in ditch wetlands (DWs), riverine wetlands (RiWs) and reclaimed wetlands (ReWs) along a 100-year chronosequence of reclamation in the Pearl River Delta. In total, 16 OCPs were measured to investigate the effects of wetland reclamation and reclamation history on OCP levels. Our results showed that average ∑DDTs, HCB, MXC, and ∑OCPs were higher in ...

Mitigation of Climate Change through Land Reclamation with Biosolids: Carbon storage in reclaimed mine soils, life cycle analysis of biosolids reclamation, and ecosystem services with reforestation

Reclaiming soils to sustain maize and soybean productivity in the Midwestern US given climate change

I build a model that explains Midwestern US maize and soybean yield as a function of weather and soil capability. Climate change is expected to reduce mid-century maize and soybean yields in the Midwest by 8% to 28% and 7% to 23%, respectively, depending on cropped land’s soil capability and severity of climate change, compared to baseline values calculated with no climate change. I find that s...
