This study examined the association of air, land, and water variables with the first historical occurrence and current distribution of toxic Prymnesium parvum blooms in reservoirs of the Brazos River and Colorado River, Texas (USA). One impacted and one reference reservoir were selected per basin. Land cover and use variables were estimated for the whole watershed (WW) and a 0.5-km zone on either side of streams (near field, NF). Variables were expressed in annual values. Principal component and trend analyses were used to determine (1) differences in environmental conditions before and after the 2001 onset of toxic blooms in impacted …

The reuse of winery wastewater (WW) could provide an alternative water source for vineyard irrigation.The shift of many wineries and other food processing industries to K+-based cleaners requires studies onthe effects of K+on soil hydraulic conductivity (HC). Depending on clay content and mineral composition,K+additions can affect the HC either positively or negatively. Soil mineralogy was anticipated to exhibita strong influence on HC responses and, therefore, soils of contrasting mineralogy were evaluated forchanges in soil HC resulting from applications of solutions elevated in Na+and K+. To examine the impactof mineral-ion relationships on HC, soils dominant in montmorillonite, vermiculite, or kaolinite from …
