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...
Climatology of atmospheric blocking 1978-2008 : global and hemispheric breakdown, as well as impacts of temperature, and global climate cycles
(University of Missouri--Columbia, 2010)
by the increase in the number of observations from the area around Siberia. The connection to the PDO, which is still a relatively new phenomena in meteorology need additional study. The connection between blocking and the PDO can have wide impacts in forecasting....
Imidacloprid sorption and transport in cropland, grass buffer and riparian buffer soils
(University of Missouri--Columbia, 2016)
(OC) was the strongest predictor of ICD sorption (p less than 0.0001). The column transport study found peak concentrations of ICD at 5.83, 10.84 and 23.8 pore volumes for crop, grass VBS, and riparian VBS, respectively. HYDRUS-1D results indicated...
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 ...
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...
Polyacrylamide amendment for erosion and runoff control on soils of differing characteristics
(University of Missouri--Columbia, 2009)
, RO, and SL within soils. For reducing SL, a high level of PAM had better performance at a steep slope compared to a low level of PAM or [less than or equal to] 40% slope. Generally, the applications of PAM amendment were not effective in reducing RO...
The use of geomorphological and pedological soil characteristics to assess planar borrowing at a Mandan Indian village, North Dakota
(University of Missouri--Columbia, 2011)
The Double Ditch State Historic Site is situated in a loess landscape immediately east of the Missouri River near Bismarck, North Dakota. The site was occupied from ca AD 1450 to 1785 by Mandan Indians, Plains Villagers who exhibited a systematic...
Cover crop effects on corn plant water uptake and soil health
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cover crops (CC), close growing crops that provide soil and seeding protection between periods of normal cash crop production or between trees in orchards or vines in vineyards...
A tall tower wind investigation of northwest Missouri
(University of Missouri--Columbia, 2007)
With energy needs on the rise and our current energy consumption methods polluting the atmosphere, it is the right time to look at alternative forms of energy production. Six Tall Tower wind observation sites were studied in Northwestern Missouri...
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...
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 ...
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...
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 ...
Streambank erosion and risk assessment of contaminant transport in Missouri watersheds
(University of Missouri--Columbia, 2010)
Sedimentation and herbicide are significant water quality concerns in claypan watersheds. Two separate watershed-scale studies were conducted in the Central Claypan Region of northeastern Missouri. One project investigated the effects of season...
The effect of soil texture, water supply, and nutrient supply upon the root development of maize
(University of Missouri--Columbia, 1914)
After summarizing previous experiments pertaining to soil texture, water supply, and nutrient supply on various plants, specifically grains, he details his own experiments on these effects on the root development of maize. ...
Playa wetland plant and soil response to predicted climate and land use change in the southern Great Plains
(University of Missouri--Columbia, 2019)
"To assess potential risks to playas in a changing climate, weaddressed the following objectives: (1) quantify effects of changing climatic conditions on plant germination and community composition, soil chemistry, greenhouse ...
Risk and stability of phosphate-immobilized lead in contaminated urban soil and mining sites in the Jasper County Superfund Site
(University of Missouri--Columbia, 2007)
-contaminated urban site, a mill-waste contaminated site, and a mining-waste contaminated site within the Jasper County Superfund Site, Southwestern Missouri. Field plots at the urban site were treated with phosphoric acid at a rate of 10 g kg⁻¹ using surface...
Degradation and transport of veterinary antibiotics and estrogens in a vegetated buffer strip system
(University of Missouri--Columbia, 2022)
). Buffer widths were 0, 2, 5, and 9 m. Degradation experiment results for SMZ and LIN in soil followed pseudo first-order kinetics and showed that soil half-lives (t0.5) for SMZ ranged from 17.8-30.1 d, with no significant differences in degradation...
