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...
Imidacloprid sorption and transport in cropland, grass buffer and riparian buffer soils
(University of Missouri--Columbia, 2016)
sorption and column leaching experiments were performed using soils collected from cropland (crop), grass vegetative buffer strips (VBS), and riparian VBS. Single-point, solid-to-solution partition coefficients (Kd) were determined by reacting soil...
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...
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...
A study of the physical and chemical properties of the soil as influenced by cowpea culture
(University of Missouri--Columbia, 1913)
In the past twenty-five years much experimental work has been done with cowpeas, in relation to cultural methods, fertilization, and variety tests, but practically nothing has been written with regard to the direct effect ...
Influence of characters of ear and kernel upon the germination of maize
(University of Missouri--Columbia, 1912)
of the ear and kernel which have a marked influence upon the yield. This is so universal that we have score cards which set forth the ideal type of ear and give certain values to the different characters. In general, the score cards are alike and all agree...
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...
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 ...
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 ...
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...
