Fig. 5. Predicted volume of band-affected soil in the surface 15 cm from annual and biannual band applications on a 76-cm spacing in a Mexico soil. Assumes cumulative volume of undisturbed bands. Band volume at 18 mo for annual applications is sum of 6 and 18 mo volumes; at 24 mo, it is the sum of 12 mo and an extropolated value from 18 mo.
