Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
and water quality and given rise to non-point source pollutants. The claypan soil region of Missouri has a high runoff potential that increases the possibility of transport of non-point source pollutants to downstream sites. The Agricultural Policy...
Use of green manures & cover crops for the south
(University of Missouri--Columbia, 1907)
The problem of restoring the fertility to the worn soils and of maintaining that of the new or fresh soils is perhaps the most serious one with which the farmers of the cotton states are confronted. It is indeed unfortunate ...
Anthropogenic effects on soil physical, chemical, and biological properties in the Missouri Ozarks
(University of Missouri--Columbia, 2018)
are understudied relative to agronomic systems with respect to soil health. The primary objective of this study was to enhance the understanding of forest soil health in the Missouri Ozarks via three research objectives: (1) quantification of the effects...
Polyacrylamide amendment for erosion and runoff control on soils of differing characteristics
(University of Missouri--Columbia, 2009)
The use of anionic polyacrylamide (PAM) as a soil amendment is an emerging conservation practice. However, guidelines have not been developed with considerations of soil properties and topographic characteristics. The ...
Assessing impacts and targeting of agricultural conservation practices
(University of Missouri--Columbia, 2010)
The U.S. Department of Agriculture initiated the Conservation Effects Assessment Project in 2003 to quantify water quality and wildlife benefits of conservation programs funded by the 2002 Farm Security and Rural Investment Act. This study examined...
Methods for high-resolution soil-landscape modeling in midwest upland landscapes
(University of Missouri--Columbia, 2008)
. These methods were tested in the upland landscapes of northern Missouri. Sensors, especially DRS, successfully estimated profile clay and organic carbon. Peak functions were valuable for modeling profile clay content and covariates of clay. Coherent depth...
Forest harvest effects on soil chemical properties and nutrient concentrations in Ozark Highland soils
(University of Missouri--Columbia, 2010)
Mixed hardwood systems of the Missouri Ozark Forest Ecosystem Project are harvested using clearcutting (CC) and single-tree selection (STS) regeneration methods. This work indicates possible effects of regeneration method on surface soil nutrient...
Forecasting wind speeds at tall tower heights within Missouri
(University of Missouri--Columbia, 2022)
Forecasting of wind speeds is necessary for the planning and operations of the wind power generating plants. This research investigates the short term forecasting of wind speeds at tall tower heights for stations within Missouri: Columbia, Neosho...
Greenhouse gas emissions and soil microbial activity for selected land use systems in floodplains
(University of Missouri--Columbia, 2022)
and droughts (IPCC, 2021). An estimated 23 percent of total anthropogenic greenhouse gas emissions (2007-2016) derive from agriculture, forestry, and other types of land use. Land management activities affect the soil microbiome and thus greenhouse gas (GHG...
Impacts of soil management practices on soil fertility in potato-based cropping systems in the Bolivian Andean highlands
(University of Missouri--Columbia, 2010)
Due to changes in climate and socioeconomic developments, current soil management practices in the Bolivian Andean Highlands may be increasing soil degradation thereby threatening food security. A study was established in ...
Playa wetland plant and soil response to predicted climate and land use change in the southern Great Plains
(University of Missouri--Columbia, 2019)
, and microbial community and structure; (2) compare ecosystem response to changing climatic conditions between Northern (Nebraska) and Southern (Texas) playa soils; and (3) assess effectsof increased agricultural nitrogen inputs on playa plant communities...
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 ...
