In the saline/sodic and sodic soils of the northern Great Plains, subsurface drainage can inadvertently result in clay particle dispersion if the surface soils are leached with rainwater. Under these conditions, penetration resistance (PR) in wet soil can be used to examine the effectiveness of free drainage (FD) vs. no drainage (ND) treatments and surface amendments consisting of a high rate of gypsum (GH), a low rate of gypsum (GL), spent lime (SL, a byproduct from the processing of… CONTINUE READING
