Alfalfa Responses to Gypsum Application Measured Using Undisturbed Soil Columns
Gypsum is an excellent source of Ca and S, both of which are required for crop growth. Large amounts of by-product gypsum [Flue gas desulfurization gypsum-(FGDG)] are produced from coal combustion in the United States, but only 4% is used for agricultural purposes. The objective of this study was to evaluate the effects of (1) untreated, (2) short-term (4-year annual applications of gypsum tota...
متن کاملTransport and Accumulation of Heavy Metals in Undisturbed Soil Columns
The podzolic soils of the Kola Peninsula, Russia, have in localised areas been highly contaminated with copper and nickel from smelting activities. Migration and retention of these metals were investigated in undisturbed soil columns irrigated with simulated background and polluted precipitation in order to study the temporal processes of retention and release within the soil. The mineral layer...
متن کاملCharacterization of preferential flow in undisturbed, structured soil columns using a vertical TDR probe.
Rapid movement of agricultural chemicals through soil to groundwater via preferential flow pathways is one cause of water contamination. Previous studies have shown that time domain reflectometry (TDR) could be used to characterize solute transport in soil. However, previous studies have only scarcely addressed preferential flow. This study presents an extended application of TDR for determinin...
متن کاملPrediction of Dispersivity for Undisturbed Soil Columns from Water Retention Parameters
ity D/v (L), that can be related solely to characteristics of the porous medium (Fried and Combarnous, Dispersivity ( ) is a required input parameter in solute-transport 1971). Dispersivity is a required input parameter in conmodels based on the advection-dispersion equation (ADE). Normally is obtained from miscible-displacement experiments. This depentaminant transport models based on the ADE ...
متن کاملSuitability Assessment of Ohio's Soils for Soil- Bases Wastewater Treatment
Each of Ohio's 467 soil series was assessed to determine the depth of the soil to bedrock, the depth to a limiting soil condition, the depth to seasonal saturation, and the soil permeability. Each soil series was placed into one of three categories; suited for traditional leach fields or mound systems, suited for mound systems only, or not suited for soil-based treatment. In a mound system, a l...
