Glyphosate affects soybean root exudation and rhizosphere micro-organisms
In vitro bioassays showed that glyphosate in the exudates stimulated growth of selected rhizosphere fungi, possibly by providing a selective C and N source combined with the high levels of soluble carbohydrates and amino acids associated with glyphosate treatment of the soybean plants. Expand
Glyphosate and glyphosate-resistant crop interactions with rhizosphere microorganisms
The specific microbial indicator groups and processes were sensitive to impacts of GR crops and are part of an evolving framework in developing polyphasic microbial analyses for complete assessment of GR technology that is more reliable than single techniques or general microbial assays. Expand
Determination of bacterially derived auxins using a microplate method
The microplate method was developed and compared to a standard method for assays of auxin compounds produced by bacteria, similar to the standard method in accuracy of determination, required less chemical reagents, and considerably reduced the time required for analyses. Expand
Cyanide Production by Rhizobacteria and Potential for Suppression of Weed Seedling Growth
The results suggest that HCN produced in the rhizospheres of seedlings by selected rhizobacteria is a potential and environmentally compatible mechanism for biological control of weeds. Expand
Differences in Yields, Residue Composition and N Mineralization Dynamics of Bt and Non-Bt Maize
Cultivation of genetically modified crops may have several direct and indirect effects on soil ecosystem processes, such as soil nitrogen (N) transformations. Field studies were initiated inExpand
Assessing changes in soil microbial communities and carbon mineralization in Bt and non-Bt corn residue-amended soils
It is concluded that incorporation of Bt residue with higher lign in content and lignin/N ratio in soil significantly affected the structure of microbial communities compared with theresidue from its non-Bt isoline. Expand
Glyphosate effects on photosynthesis, nutrient accumulation, and nodulation in glyphosate-resistant soybean
To reduce potential undesirable effects of glyphosate on plant growth, application of the lowest glyphosate rate for weed-control efficacy at early growth stages (V2 to V4) is suggested as an advantageous practice within current weed control in GR soybean for optimal crop productivity. Expand
Understanding and Enhancing Soil Biological Health: The Solution for Reversing Soil Degradation
Our objective is to provide an optimistic strategy for reversing soil degradation by increasing public and private research efforts to understand the role of soil biology, particularly microbiology,Expand

An overview of the effects of microorganisms on weed seed viability relative to seed bank depletion, and how this information can be applied to weed management is provided. Expand
Soil enzyme activities and physical properties in a watershed managed under agroforestry and row-crop systems
The proportion of water-stable aggregates (WSA) and a diverse microbial activity influence soil quality, crop growth, nutrient retention, water infiltration, and surface runoff. The objective of theExpand
