The effect of liming an acid soil on the growth of certain legumes
(University of Missouri--Columbia, 1914)
the air by symbiotic fixation. A minor experiment was added to determine the effect of quantities of organic matter on the location of nodules. In working on these problems it was found possible to obtain information of other points of interest...
Control of the humus supply of certain important Missouri soils
(University of Missouri--Columbia, 1908)
treatments upon the humus content of Missouri soils two lines of experiment were carried out. First, a study of the effect of crop rotation and manures upon the humus and nitrogen content of soils as evidenced in the rotation plats of the Missouri Experiment...
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...
The effect of different nutritive planes upon the economy of gain and the rate of growth of young cattle
(University of Missouri--Columbia, 1909)
This investigation was undertaken in order that something might be learned concerning: (a) the cost of maintenance of live weight in ungrown cattle; (b) the effect of a maintenance ration upon the condition of ungrown ...
Impacts of municipal wastewater effluent on seed banks, chemistry, and microorganisms of soils excavated from wetland impoundments designated for wildlife
(University of Missouri--Columbia, 2009)
To evaluate the effects of municipal wastewater effluent (WWE) and Missouri River water (MOR) as irrigation sources on soil chemistry, seed banks, and microorganisms, a field study was conducted in conjunction with a set of greenhouse studies...
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...
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...
Optimizing crop N use efficiency using polymer-coated urea and other N fertilizer sources across landscapes with claypan soils
(University of Missouri--Columbia, 2008)
Development of improved management practices to increase nitrogen use efficiency (NUE) within agricultural fields is needed to improve crop production and reduce nitrogen (N) loss. Field studies planted to maize were conducted in 2005 and 2006...
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...
Analysis of twenty-five years of heavy rainfall events in the Texas Hill Country
(University of Missouri--Columbia, 2008)
climate stations in the region; the period examined for this study was 1982-2006. Days with measurable precipitation were treated as a gamma distribution in order to determine the top 2%, 1%, and 0.5% to define events as unusual, rare, and extreme...
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 ...
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 ...
Effects of a consortia probiotic inoculant on soil microorganisms and impacts on autoinducers employed in quorum sensing
(University of Missouri--Columbia, 2013)
Disease control in plant agriculture is largely achieved through application of various antimicrobials. Manipulation of indigenous soil microbial communities received attention as it promises improved pathogen control and enhanced plant outputs...
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...
Effects of prescribed fire on forest soil properties in the Ozark Highlands
(University of Missouri--Columbia, 2020)
/Forest Hills Land Type Association in the Black River Basin of southern Missouri. Weathered from Roubidoux sandstone and Gasconade dolomite, soils at the study sites contain large quantities of coarse fragments and reduced nutrient content. In 2015, fire...
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...
The relation of size, shape, and number of replications of plats to probable error in field experimentation
(University of Missouri--Columbia, 1916)
Introduction: Altho large numbers of experiments that attempt to measure small variations of characteristics in variety tests or slight differences resulting from unlike soil treatments or tillage operations are conducted each year, comparatively...
