A Study of the effect of liming an acid soil on the growth of certain legumes and non-legumes
(University of Missouri--Columbia, 1914)
have been heavy or applied immediately before the growth of plants. P.E. Karraker at this Station observed a depressing effect of ground limestone on the growth of certain legumes. It was purposed in the experiments herin reported to continue the work...
Alternative tillage and nitrogen management options to increase crop production and reduce nitrous oxide emissions from claypan soils
(University of Missouri--Columbia, 2010)
The Central Claypan Region covers an area of 10 million acres of claypan or claypan-like soil in Missouri, Oklahoma, Kansas, Iowa, and Illinois. Agricultural production on claypan soil can have lower yield and a greater impact on the environment...
Comparison of rainfall energy and soil erosion parameters from a rainfall simulator and natural rain
(University of Missouri--Columbia, 2007)
. In this study, an optical rainfall imaging system was used to determine the drop-size distributions (DSDs) of natural rain in Missouri. These observations have been compared to those from an indoor gravity rainfall simulator. This thesis reports the results...
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...
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...
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...
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...
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...
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 ...
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 ...
Application of a digital terrain model for forrest land classification and soil survey
(University of Missouri--Columbia, 2004)
Models (DEM's) to produce Digital Terrain Models (DTM's) in the Missouri Ozarks. Terrain models produced from several DEM sources were evaluated for their accuracy in predicting slope, aspect and landforms on a 3691 ha area. The DEM's created from USGS...
