Influence of Herbicide Triasulfuron on Soil Microbial Community in an Unamended Soil and a Soil Amended with Organic Residues
The effect of organic amendments and pesticides on a soil microbial community has garnered considerable interest due to the involvement of microorganisms in numerous soil conservation and maintenance reactions. The aim of this work was to assess the influence on a soil microbial community of the simultaneous application of the herbicide triasulfuron at three doses (2, 10, and 50 mg kg-1), with ...
متن کاملChanges in Soil Organic Matter, Enzymatic Activities and Hea Vy Metal Av Ailability Induced by Application of Organic Residues
A 3-year field experiment on a sandy soi] supporting a strawberry crop was carried out to study the effects of the application of three organic residues (AC, olive mill wastewater sludge compos!; MWC, municipal solid waste compost; and PW, paper mill waste) on organic matler content, enzymatic activities, and available heavy metals. Significant increases in organic carbon content (total organic...
متن کاملcarbon and nitrogen mineralization in a calcareous soil amended with plant residues and sulfur
carbon (c) and organic nitrogen (n) mineralization processes play key roles in supplying nutrient elements essential for plant growth. on the other hand, since the low organic matter content of agricultural soils of arid and semi-arid areas, microbial activities are often limited by carbon in these types of soils. enhancement of microbial activities and populations could be achieved by returnin...
متن کاملCadmium from soil amended with sewage sludge: effects and residues in swine.
Liquid digested sewage sludge from a Chicago waste treatment plant was applied to experimental corn plots starting in 1968. The treatment plant received a high proportion of industrial effluent and the sludge averaged about 200 ppm Cd (dry weight). Corn grain harvested from the plots in 1974 was fed to growing swine for 56 days, and other swine were permitted to forage on the plots during the w...
متن کاملS-Metolachlor sorption in soils amended with olive oil residues: effect of organic waste transformation
Herbicides are the main type of pesticides causing water contamination. The chloroacetanilide herbicide Smetolachlor is frequently detected in ground and surface waters, and represents a potential source of water pollution. The addition of organic residues to soils to reduce losses of organic pollutants constitutes sometimes an efficient method to control contamination. One of the recent techno...
