Microbial community structure in a silty clay loam soil after fumigation with three broad spectrum fungicides
(Taylor & Francis, 2008-04)
The short-term effect of three broad spectrum fungicides on microbial activity, microbial biomass, soil ergosterol content, and phospholipid fatty acid (PLFA) profiles was studied. A silty clay loam soil was treated ...
Chemical variables influencing microbial properties in composted tannery sludge-treated soil
(Springer, 2018-08-01)
Repeated applications of composted tannery sludge to arable soils have the potential to greatly alter soil chemistry and thus potentially influence the soil microbial community over time. This study performed multivariate ...
Microbial populations and activities in sewage sludge and phosphate fertilizer-amended soil
(Elsevier B.V., 1996-07-01)
A greenhouse study was conducted to determine the number of microbial populations and activities in sewage sludge and phosphate fertilizer-amended dark red latosoil for cultivation of tomato plants. Sewage sludge was applied ...
Humic fractions of forest, pasture and maize crop soils resulting from microbial activity
(Sociedade Brasileira de Microbiologia, 2014-09-01)
Humic substances result from the degradation of biopolymers of organic residues in the soil due to microbial activity. The objective of this study was to evaluate the influence of three different ecosystems: forest, pasture ...
Tannery sludge compost amendment rates on soil microbial biomass of two different soils
(Elsevier France-editions Scientifiques Medicales Elsevier, 2011-03-01)
Composting is recognized as one of the most cost-effective and environmentally sound alternatives for organic waste recycling. Long-composted wastes have the potential to substitute for inorganic fertilizers. We investigated ...
Anticancer and apoptosis-inducing activities of microbial metabolites
(Pontificia Universidad Católica de Valparaíso, 2010)
Effect of deforestation on soil microbial activity a worm-composite can improve quality? A microcalorimetric analysis at 25 °C
(Elsevier Science, 2002-10)
All crops grow in the soil environment; thus, soil properties are of great importance to determine plant and crop conditions. An index to assess soil fertility is its microbial activity. In this sense, in the present work ...
Soil ecotoxicity assessment of glyphosate use under field conditions: microbial activity and community structure of Eubacteria and ammonia-oxidising bacteria
(John Wiley & Sons Ltd, 2016-04)
A plot-scale experiment was conducted to assess the impact of field application rates of glyphosate on soil microbial communities by taking measurements of microbial activity (in terms of substrate-induced respiration and ...
Soil microbial communities under different soybean cropping systems: characterization of microbial population dynamics, soil microbial activity, microbial biomass, and fatty acid profiles
(Elsevier Science, 2009-05)
This work analyzes the direct effect of soil management practices on soil microbial communities, which may affect soil productivity and sustainability. The experimental design consisted of two tillage treatments: reduced ...
Soil microbial properties after 5 years of consecutive amendment with composted tannery sludge
(Springer, 2015-01-01)
Composting has been recognised an alternative method to tannery sludge recycling and afterwards to be used in agriculture. As the tannery sludge contains salts and chromium, the application of composted tannery sludge (CTS) ...
