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...
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 ...
