Abstract

Diagnostic techniques to evaluate cultural practice effectiveness for
managing soil strengths are needed. A recording penetrometer used on a
uniform grid of penetrations produced analog records (on 3 x 5 cards)
of soil strength vs depth. These were used to develop profile contour
plots of soil strength. Digitization was done using a flatbed plotter,
programmed to aid in placement of the digitizing eyepiece. Contour
depth, shape, and frequency of strength observations were used to
compare tillage treatments. Methods of strength correction for soil
water differences and other applications are discussed.
