Optimizing crop N use efficiency using polymer-coated urea and other N fertilizer sources across landscapes with claypan soils
(University of Missouri--Columbia, 2008)
in the claypan region of north central and northeast Missouri to determine the effects of landscape position and soil depth to the claypan on crop growth and N uptake, and to examine the use of a variable-source N fertilizer application strategy to optimize crop...
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 ...
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...
Use of different sources and rates of foliar potassium with glyphosate to overcome environmental- and management-induced K deficiency in soybeans
(University of Missouri--Columbia, 2007)
The incidence of potassium (K) deficiency in soybeans [Glycine max (L.) Merr] has increased over the last few years in Missouri and other Midwestern states. Postemergence application of foliar K fertilizer would have the ...
Use of slow-release N fertilizer to control nitrogen losses due to spatial and climatic differences in soil moisture conditions and drainage in claypan soils
(University of Missouri--Columbia, 2006)
Agricultural soils are a major source of nitrous oxide (N₂O) which has a significant environmental impact on global warming and ozone depletion. However, there is little information on soil N₂O emissions under different ...
Characterization of agroforestry feedstocks and their biochars and their effects on soil greenhouse gas emissions in a floodplain soil
(University of Missouri--Columbia, 2018)
The temperature at which biochar (biocharcoal) is produced is a major factor that determines its chemical and structural characteristics. The objectives of this research were to assess the effects of feedstock source among ...
Nitrogen management strategies to improve corn growth and reduce soil greenhouse gas emissions from claypan soils
(University of Missouri--Columbia, 2018)
Adoption of nitrogen (N) management strategies to minimize gaseous N loss from agriculture while maintaining high yield production is increasingly important for an exponentially growing population. Agricultural management ...
