Evaluating and improving corn nitrogen fertilizer recommendation tools across the U.S. Midwest
(University of Missouri--Columbia, 2018)
to evaluate the performance of publicly-available N fertilizer recommendation tools across a wide range of soil and weather environments for 1) prescribing EONR for planting and split N fertilizer applications, 2) improve understanding of the economic...
Methods for high-resolution soil-landscape modeling in midwest upland landscapes
(University of Missouri--Columbia, 2008)
Traditional soil mapping concepts do not sufficiently address the spatial resolution of some soil management problems. Continuous models of soil profiles and landscapes are needed to move beyond the categorical paradigm ...
Variability of soil hydraulic properties and estimation of plant-available water on claypan-soil landscapes
(University of Missouri--Columbia, 2007)
these properties for claypan-soil landscapes in Central Missouri. The objectives were: (1) to evaluate the effects and interactions of conservation management, landscape position and the claypan layer on hydraulic properties including saturated hydraulic...
An environmental assessment of sensor-based variable-rate nitrogen management in corn
(University of Missouri--Columbia, 2006)
Nitrogen (N) fertilizer unused by the crop is left to the fate of the processes of the N cycle, and can eventually lead to nitrate contamination of surface and ground waters. In order to address this problem, various methods ...
