Nitrogen management strategies to improve corn growth and reduce soil greenhouse gas emissions from claypan soils
(University of Missouri--Columbia, 2018)
. The objective of this study was to determine the effects of urea fertilizer placement with and without the addition of a nitrification inhibitor (NI) on corn yield, N use efficiency (NUE), and cumulative soil N[2]O emissions on a Northeastern Missouri claypan...
Forage production and diversification for climate-smart tropical and temperate silvopastures
(University of Missouri--Columbia, 2019)
. We examined three distinct silvopastures, two in the country of Panama and one in the state of Missouri, to better understand how the integration of woody perennial trees and shrubs affects forage productivity, availability, and nutritional value...
Canopy recruitment dynamics in naturally regenerated longleaf pine (pinus palustris) woodlands
(University of Missouri--Columbia, 2017)
The ecological and cultural values of the longleaf pine (Pinus palustris) ecosystem, in combination with an approximately 97 percent loss in historic range, has led to increasing interest in ecosystem restoration and ...
Flower production and effect of flower harvest on berry yields within six American elderberry genotypes
(University of Missouri--Columbia, 2017)
production of American elderberry flowers is nascent. A large field experiment with American elderberry was established in 2015 in southwest Missouri, U.S.A to evaluate flower production and to determine the impact of a partial flower harvest on fruit yield...
Agroforestry buffer, biomass crop, and grain crop effects on soil quality and soil water use
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Soil degradation, impaired water quality, and reduced soil organic carbon have become major concerns in the management of degraded claypan soils with their associated ecological...
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 ...
Investigating denitrification from two Missouri claypan soils
(University of Missouri--Columbia, 2020)
. The research sites consisted of two claypan soil fields in Central Missouri. Several sets of soil cores were collected in triplicate in two landscape transects across both fields and N2 and N2O production were measured using a gas flow soil core incubation...
Heterogeneity in body condition, survival, and seasonal origins among lesser snow and Ross's geese
(University of Missouri--Columbia, 2018)
condition among hunter harvested individuals and the general population of midcontinent lesser snow and Ross's geese during the spring Light Goose Conservation Order in 2015 and 2016 across Arkansas, Missouri, Nebraska, and South Dakota. I found a body...
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. leaching and denitrification...
Northern bobwhite brood ecology and population dynamics in southwest Missouri
(University of Missouri--Columbia, 2020)
Northern bobwhite (Colinus virginianus) have experienced widespread, long-term population declines. Bobwhite populations in Missouri have declined 2.7% annually between 1966 and 2015, and 3.5% annually between 2005 and 2015, for a cumulative loss...
Characterization of agroforestry feedstocks and their biochars and their effects on soil greenhouse gas emissions in a floodplain soil
(University of Missouri--Columbia, 2018)
The temperature at which biochar (biocharcoal) is produced is a major factor that determines its chemical and structural characteristics. The objectives of this research were to assess the effects of feedstock source among ...
Quantifying neonicotinoid concentrations in Missouri wetlands, their driving factors, and the potential effects on the reliant avian community
(University of Missouri--Columbia, 2018)
been proposed as indicator taxa as they are reliant on insect food reserves and have recently experienced population declines. Thus, we developed two studies in floodplain wetlands to quantify neonicotinoids in Missouri wetlands and potential effects...
Identifying bioactive compounds from switchgrass (panicum virgatum L.) by global metabolomic analysis
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Untargeted metabolite profiling of switchgrass using cloud metabolomics platform. Integrated biorefining incorporates biomass conversion processes and equipment to produce...
Agroforestry adoption: influential factors, land manager perceptions, and willingness-to-accept payments
(University of Missouri--Columbia, 2021)
,' ‘income,' and ‘fertile soil' displayed complex, inconsistent, or context-specific relationships with agroforestry. These results informed the design of a survey for Missouri land managers. The survey uncovered low levels of agroforestry knowledge among...
Identification and characterization of health-promoting benefits and bioactive molecules in black walnuts (Juglans nigra l.) and waste materials from agroforestry systems
(University of Missouri--Columbia, 2020)
selected and cultivated for nut production by the University of Missouri - Center for Agroforestry (Columbia, MO, USA). Additionally, it is likely that the bioactive activities of black walnut are correlated with its bioactive constituents including...
