Variability of soil hydraulic properties and estimation of plant-available water on claypan-soil landscapes
(University of Missouri--Columbia, 2007)
PAW capacity can be approximated at a field scale using a theoretical two-layer soil profile, i.e., a silt-loam topsoil layer and a siltyclay subsoil layer; and (3) to evaluate relationships of measured PAW capacity with measured corn grain yield...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
Water and soil are two key elements for life on this planet, and improving and preserving their quality are of prime importance. Various human actions including use of intensive chemicals in agriculture have accelerated ...
