Spatial variability of microbial properties in prairie soils
(International Union of Soil Sciences, 2006-07)
Soil microbial activity plays a key role in processes that affect ecosystem functions. Disturbances by management practices may change microbial biomass and activity. Inherited or due to management practices, soil microbial ...
Response of Microbial Community to Management Systems in Prairie Soils
Soil microbial activity mediates processes that affect ecosystem functions. Disturbances by management practices may change microbial biomass and activity. The specific objectives were to reveal heterogeneity of chemical, ...
Characterization of redox-related soil microbial communities along a river floodplain continuum by fatty acid methyl ester (FAME) and 16S rRNA genes
Redox states affect substrate availability and energy transformation, and, thus, play a crucial role in regulating soil microbial abundance, diversity, and community structure. We evaluated microbial communities in soils ...
Impact of Long-Term Cultivation of Alfalfa, Bermudagrass, Switchgrass, and Winter Wheat On Soil Biogeochemical Properties
(Oklahoma State University, stillwater, OK, 2010-11-03)
With increasing interest in plant derived biofuels as an alternative source of energy, accessing the effect of bioenergy crop production on soil quality is vital for preserving sustainability of the production system. ...
Spatial structure of microbial biomass and activity in prairie soil ecosystems
Management of soil ecosystems requires assessment of key soil physicochemical and microbial properties and the spatial scale over which they operate. The objectives were to determine the spatial structure of microbial ...
Soil Management Induced Changes in Active Phosphorus Pools and Activities of Phosphatases in Mixed Prairie Ecosystems
Understanding phosphorus (P) cycling and dynamics of soil P pools are important in developing management practices to maintain ecosystem health. The objective was to determine impacts of management practices on different ...
Effect of Grazing and Cultivation on Activities of Enzymes Involved in Carbon and Nitrogen Cycles
(ASA, Madison, WI., 2006-11-13)
As the key factors regulating C and N cycling in soil ecosystems, activities of 11 enzymes involved in C and N transformation, and microbial biomass C and N were evaluated to assess impacts of grazing and cultivation on ...
Drivers in Soil Ecosystem Function: Enzyme Activities and Carbon, Nitrogen, Phosphorus, and Sulfur Contents
(Oklahoma State University, stillwater, OK, 2009-11-04)
Understanding interactions and dynamics among different nutrient pools and enzyme activities that govern their cycling processes under different management practices could assist the evaluation and development of management ...
Sulfur Dynamics and Activities of Sulfur-Transforming Enzymes in Prairie Soils
(Oklahoma State University, stillwater, OK, 2008-10-07)
Maintaining ecosystem health and function are essential for sustaining agricultural production. Understanding sulfur (S) cycling in the soil environment is important in assessing ecosystem functions that may be directly ...
