Variability of soil hydraulic properties and estimation of plant-available water on claypan-soil landscapes
(University of Missouri--Columbia, 2007)
and landscape position, intact soil core samples (76 by 76 mm) were taken from the 0- to 10-, 10- to 20-, and 20- to 30-cm soil depths. For objective 2, soil profile samples were taken at 18 to 19 locations from each of two close-by fields and PAW capacity...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
/Environmental eXtender (APEX) model was calibrated and validated for a 32-ha field from 1993 to 2002 for runoff, sediment, and atrazine loads. Two indices were developed using soil property and topography data, the Conductivity Claypan Index (CCI) and the Claypan...
