Cover crop and rotation intensity effects on soil health and yield in corn-soybean cropping systems
(University of Missouri--Columbia, 2020)
stable aggregates, soil moisture, total organic carbon, active carbon, potentially mineralizable nitrogen (PMN), and soil microbial community composition via a phospholipid fatty acid (PLFA) analysis were measured in 2017 and 2018 in Columbia, MO under no...
Competition and management of volunteer corn (Zea Mays L.) in corn
(University of Missouri--Columbia, 2011)
(10, 20, and 40 cm) in glufosinate-resistant or imidazolinone-tolerant hybrids, respectively. Research was conducted during 2008, 2009, and 2010 at multiple locations throughout central and northeast Missouri. Harvest inefficiencies resulted in kernels...
Comparing mosquito communities of various patch-matrix landscape combinations in central Missouri, with implications for developing models to forecast abundances of important mosquito taxa
(University of Missouri--Columbia, 2010)
Disease vector population densities, combined with their relationship to landscape characters, will clearly affect the proliferation of arboviruses to humans present in these landscapes. Advanced mapping techniques (e.g., ...
Integrating cover crops into crop rotations in upstate Missouri
(University of Missouri--Columbia, 2018)
"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best...
Identification, characterization, and management of glyphosate-resistant waterhemp (Amaranthus rudis sauer.) in Missouri
(University of Missouri--Columbia, 2008)
The possibility of in waterhemp has been of concern to Midwest corn and soybean producers due to a heavy dependence on glyphosate as a weed control tool and the increased incidence and problematic nature of waterhemp in ...
Efficacy of organic herbicides in agronomic crops and improvement of soil biota with organic production practices
(University of Missouri--Columbia, 2019)
-directed, organic herbicides may provide a viable alternative to continued tillage for weed management in soybean. CHAPTER IV. Response of Soil Biota to Long-term Organic Weed Control Practices. Abstract: Current weed management practices in organic systems...
Novel approaches in macroinvertebrate biomonitoring
(University of Missouri--Columbia, 2008)
The increasing popularity of benthic macroinvertebrate use for biological monitoring and assessment of lotic systems calls for new applications for regions with a lesser known fauna and an overall better understanding of ...
Resource extraction, resistance, and religion in Nicaragua
(University of Missouri--Columbia, 2019)
My dissertation examines the causes of protest over resource extraction in Nicaragua, and underlines the role of religion as a catalyst for sustained and successful challenges against resource extraction. With few exceptions, ...
Toxicogenomics of Diabrotica virgifera virgifera leconte in response to eCry3.1Ab-expressing transgenic maize
(University of Missouri--Columbia, 2019)
In modern agricultural systems, insect pests are constantly facing stresses from natural factors and pest management. Strong selection pressure results in evolution of insect resistance to control substances such as chemical ...
