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 ...
Relay- and double-crop production systems for wheat
([University of Missouri--Columbia], 2014)
Cover crops are important to provide organic matter to soils, diversify cropping systems, and provide economic benefits if the correct cropping systems are utilized. Relay-intercrop production involves overlapping growth ...
Urea fertilizer placement effects on soil greenhouse gas emissions and corn growth
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Agricultural soils are responsible for a majority of human caused greenhouse gas (GHG) production, such as N₂O and carbon dioxide (CO₂). Nitrous oxide ...
Effects of selected surfactants on nutrient uptake and soil microbial community
(University of Missouri--Columbia, 2011)
Surfactants with solvent and wetting abilities are used in the formulation of herbicides to enhance spraying capabilities. These chemicals eventually enter into the soil and may disrupt different chemical, physical and ...
Enhanced efficiency phosphorus application for corn
(University of Missouri--Columbia, 2012)
Farmers are interested in the use of enhanced efficiency phosphorus (P) fertilizer applications or treatments. The objectives of this research are (1) to determine the effects of tillage/fertilizer placement [no-till ...
Utilization of managed subsurface drainage to increase corn and forage yields and reduce nitrogen loss in poorly-drained, upland and bottomland soils
(University of Missouri--Columbia, 2014)
