Phytoplankton response to water quality threats in Midwest reservoirs
(University of Missouri--Columbia, 2021)
Harmful cyanobacterial blooms and invasive species threaten water quality. These threats are expected to worsen in the future, emphasizing the need for creative management solutions and a thorough understanding of their ...
Quantifying neonicotinoid concentrations in Missouri wetlands, their driving factors, and the potential effects on the reliant avian community
(University of Missouri--Columbia, 2018)
Neonicotinoid insecticides became available for commercial use in North America in the late 20th Century. Since their introduction, studies of surface waters where neonicotinoids are available for use have measured ...
Agroforestry buffer, biomass crop, and grain crop effects on soil quality and soil water use
(University of Missouri--Columbia, 2020)
and environmental challenges. Restoration of degraded soils by the adoption of recommended perennial vegetative management systems can rehabilitate watersheds and lead to enhancing soil health. Sustainable management practices such as trees, grasses, biomass crops...
Nitrogen management strategies to improve corn growth and reduce soil greenhouse gas emissions from claypan soils
(University of Missouri--Columbia, 2018)
depth of 8 cm (IA). The addition of a NI with deep-banded urea resulted in 27% greater apparent N recovery efficiency than all other N treatments. Additionally, DB+NI had 54 and 55% lower cumulative soil N2O emissions than IA and SA treatments in the two...
Utilizing hydrologic soil grouping to estimate corn nitrogen rate recommendations
(University of Missouri--Columbia, 2019)
Nitrogen fertilizer recommendations in corn (Zea mays L.) that match crop N need are imperative to increasing profitability and preventing environmental contamination. However, processes influencing corn production (i.e. ...
Evaluation and development of first order fire effects mortality model predictions for eastern hardwood forests
(University of Missouri--Columbia, 2018)
The First Order Fire Effects Model (FOFEM) is a useful tool for predicting fire-induced mortality in western coniferous forests. However, it lacks robust models for eastern hardwood species. Managers in the eastern United ...
