Due to climate change, the amount of rainfall, and its uneven temporal and spatial distribution, affect water availability. As a result, both households and farmers need to adapt to climate change by taking appropriate ...
Discovery and characterization of regulatory mechanisms affecting the heteromeric acetyl-coenzyme a carboxylase in Arabidopsis
(University of Missouri--Columbia, 2016)
Fatty acid biosynthesis (FAS) is an essential metabolic pathway used by all organisms to generate fatty acids. A staple component of this pathway is the enzyme acetyl-CoA carboxylase (ACCase), which catalyzes the committed ...
Organic milk demand and supply in the U.S. and implications for organic milk industry
(University of Missouri--Columbia, 2016)
can reduce the use of chemicals and synthetic fertilizers, benefit the environment and promote sustainable agricultural production. For these reasons, policy makers may consider providing more economic support for organic dairy farmers and potential...
Characterizing Impacts of Land Use and Land Cover Change on Urban Runoff Potential Using the HEC-GeoHMS Model
(University of Missouri–Kansas City, 2016)
on the Missouri side. Because of Urbanization, agricultural and forested areas within the watershed are decreasing, causing increasing rates of potential runoff. Researching runoff rates caused by LULC has not been thoroughly conducted on the Blue River and its...
Assessment of environmental variables and anthropogenic impacts on shallow marine bivalves
(University of Missouri--Columbia, 2016)
of a location. Indeed, these records are influenced by individual growth patterns as organic content of the shell is higher during growth checks. Shells analyzed from lagoons proximal to agriculture and urban settings typically have elevated levels...
Effect of far-red induced shade-avoidance responses on carbon allocation in arabidopsis thaliana
(University of Missouri--Columbia, 2016)
this change in growth causes young, growing leaves to export less of the sugar they make (keeping more for themselves), but fully mature leaves did not change how much sugar they exported. Agriculture is all about getting plants to turn sunlight into products...
Measuring and modeling suspended sediment and nutrient yields in a mixed-land use watershed of the central United States
(University of Missouri--Columbia, 2016)
inorganic nitrogen and total phosphorus yields exceeded 10.3 and 2.04 kg ha-1 yr -1 from the agricultural dominated headwaters. Multiple linear regression analyses indicated significant (CI = 0.05) relationships between pollutant loading, annual total...
Restoration at the roots : mycorrhizal interactions and habitat restoration in glades and prairies

Implications for soil health : assessing crop management systems and cover crops on mid-Ohio glaciated soils
(University of Missouri--Columbia, 2016)
demonstrated the contribution of sustainable agricultural practices such as no-till and cover crops for maintaining soil health and biological activity. Complex interactions in soil need more than a few years to change and manifest themselves; therefore...

Urea fertilizer placement effects on soil greenhouse gas emissions and corn growth
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Agricultural soils are responsible for a majority of human caused greenhouse gas (GHG) production, such as N₂O and carbon dioxide (CO₂). Nitrous oxide is a potent GHG that stays...
