Variability of soil hydraulic properties and estimation of plant-available water on claypan-soil landscapes
(University of Missouri--Columbia, 2007)
conductivity (K[subscript sat]), water retention, pore-size distributions and bulk density; (2) to investigate direct relationships between measured PAW capacity and apparent soil electrical conductivity (EC[subscript a]), and to test the hypothesis that soil...
Some factors influencing the germination of corn : a thesis
(University of Missouri--Columbia, 1908)
One line of agricultural investigation that has been much neglected is that of determining what factors may influence the germination of corn. There has been in fact no direct work done along this line that is available ...
Study of the phenomenon of barrenness in corn
(University of Missouri--Columbia, 1911)
Barrenness in corn is one of the most commonly observed phenomena exhibited by this prominent cereal, and one of the least understood. Why various, seemingly growthy and hardy stalks of corn fail to produce grain has been ...
Degradation and transport of veterinary antibiotics and estrogens in a vegetated buffer strip system
(University of Missouri--Columbia, 2022)
Knowledge of veterinary antibiotic (VA) and estrogenic hormone persistence in soil is critical to understanding environmental risks associated with these potential contaminants. Understanding sorption and transport of 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 ...
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 ...
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 ...
