Cover crop practices in Missouri claypan soils and their influences on selected soil health indicators
(University of Missouri--Columbia, 2015)Growing world human populations and diversified global markets have increased demand for agricultural food products, as well as non-food agricultural industry products. To meet these expected future demands, increasing and ... -
Effects of a consortia probiotic inoculant on soil microorganisms and impacts on autoinducers employed in quorum sensing
(University of Missouri--Columbia, 2013)Disease control in plant agriculture is largely achieved through application of various antimicrobials. Manipulation of indigenous soil microbial communities received attention as it promises improved pathogen control and ... -
Effects of selected surfactants on nutrient uptake and soil microbial community
(University of Missouri--Columbia, 2011)Surfactants with solvent and wetting abilities are used in the formulation of herbicides to enhance spraying capabilities. These chemicals eventually enter into the soil and may disrupt different chemical, physical and ... -
Impacts of municipal wastewater effluent on seed banks, chemistry, and microorganisms of soils excavated from wetland impoundments designated for wildlife
(University of Missouri--Columbia, 2009)To evaluate the effects of municipal wastewater effluent (WWE) and Missouri River water (MOR) as irrigation sources on soil chemistry, seed banks, and microorganisms, a field study was conducted in conjunction with a set ... -
Implications for soil health : assessing crop management systems and cover crops on mid-Ohio glaciated soils
(University of Missouri--Columbia, 2016)Cropping systems management and the presence or absence of cover crops directly influence many physical, chemical, and biological soil properties. The research hypothesis was the use of cover crops and a no-till crop ... -
Rhizobacteria associated with glyphosate-resistant soybean (Glycine Max)
(University of Missouri--Columbia, 2006)The research was conducted to examine the impact of GR soybean treated with glyphosate on rhizobacterial activities involved in IAA production and soil C and N mineralization in different soil management systems; to determine ... -
Soil microbial contribution to greenhouse gas efflux from a secondary forest in central Missouri
(University of Missouri--Columbia, 2011)Greenhouse gas emissions (GHG) vary with the interactions among physical, chemical, and biological characteristics of soil and microclimate. Soil microorganisms are involved in almost all soil processes, and are also ... -
Soil quality as affected by agroforestry and grass buffers in grazed pasture and row crop systems
(University of Missouri--Columbia, 2011)Establishment of agroforestry and grass buffers within agroecosystems is believed to improve soil quality. Soil enzyme activities and water stable aggregates have been identified as sensitive soil quality indicators to ... -
Soil quality assessment for an alfisol undergoing alternative organic weed management systems
(University of Missouri--Columbia, 2017)As organic agriculture farmland continues to increase on a global scale with 6.5 million hectares added during 2014-2016, the increased number of organic producers will be expected to fulfill sustainability obligations. ... -
Soil quality in organic cropping systems
(University of Missouri--Columbia, 2016)The objective of this research was to quantify soil quality indicator levels under contrasting organic practices and to provide scientific information that can lead to development of best management practices for organic ...
