Long-Term Residue And Water Management Effects On Soil Respiration And Soil Aggregate Stability In A Wheat-Soybean, Double-Crop System In Eastern Arkansas, Sharon Faye Smith

Graduate Theses and Dissertations

Sustainability in agriculture is paramount to assuring continued production from our most naturally fertile soils. Storing carbon (C) in soil as organic matter through sustainable agricultural management practices can both remove atmospheric C and improve soil quality. The objective of this study was to evaluate the long-term effects of water management (irrigation and dryland), residue management [burn and no-burn, conventional (CT) and no-tillage (NT)] and residue/fertility level (high and low) on soil respiration and aggregate stability in a wheat- (Triticum aestivum L.) soybean [Glycine max (L.) Merr.], double-crop system in a silt-loam soil (Aquic Fraglossudalf) in the Mississippi River Delta …

Fate And Transport Of Fourteen Pharmaceuticals And Personal Care Products In An Irrigated Soil Profile, Lena Wright

UNLV Theses, Dissertations, Professional Papers, and Capstones

Use of pharmaceuticals and personal care products (PPCPs) is on the rise and unfortunately, a large percentage passes through the human body. These compounds then find their way into the wastewater stream and into treatment facilities. Only a fraction of these compounds are removed from the stream prior to discharge. An environmentally acceptable alternative to discharging recycled water to rivers, lakes and other bodies of water is to use the water for irrigation of large areas of turfgrass. These PPCPs, of which some may have high mobilities in irrigated soil plant systems, may potentially impact groundwater resources. To determine the …
