Toxic effects of four sulphonylureas herbicides on soil microbial biomass.
The effect of four triazinyl-sulfonylurea herbicides (cinosulfuron, prosulfuron, thifensulfuron methyl, triasulfuron) on soil microbial biomass, soil respiration, metabolic activity, metabolic quotient, and some enzymatic activities (acid and alkaline phosphatase, β-glucosidase, arylsulphatase, and fluorescein diacetate hydrolysis) were monitored under controlled conditions over 30 days. The he...
متن کاملMicrobial Degradation of Shrimp Waste in Soil
This study presents results of research on a number of microorganisms in soil of the Chełmżyńskie lake watershed and their role in the decomposition of chitin. The authors also examined the level of respiration activity of soil in the presence of shrimp waste. Results demonstrate that the number of microorganisms in soil were variable. During the entire research period, the analyzed groups of m...
متن کاملThe Effect of Sulphonylurea Herbicides on the Microbial Activity in Soil under Maize
Depeneding on the quality and quantity of herbicides and their mode of action and soil type, the number of different groups of microorganisms in soil increased or decreased. Sulphonylurea herbicides belong to a group of pesticides which in doses of only a few grams per hectar are sufficient to control weeds. The mode of action of these herbicides is based on blocking the enzyme acetolactate syn...
متن کاملDegradation of the Fungicides, Azoxystrobin and Difenoconazole in Soil and their Influence on Soil Microbial Activity
The non-target effects of Amistar (azoxystrobin) and Score (difenoconazole) were studied in terms of changes in the soil microbial populations, soil respiration and activity of soil enzymes. Both the fungicides significantly reduced the fungal population in the soils even at the lowest concentration used (0.44 g. (a.i.) g soil) and totally eliminated it at the recommended dose for field applica...
متن کاملDegradation of chlorpyrifos in laboratory soil and its impact on soil microbial functional diversity.
Degradation of chlorpyrifos at different concentrations in soil and its impact on soil microbial functional diversity were investigated under laboratory condition. The degradation half-live of chlorpyrifos at levels of 4, 8, and 12 mg/kg in soil were calculated to be 14.3, 16.7, and 18.0 d, respectively. The Biolog study showed that the average well color development (AWCD) in soils was signifi...
