Strip-cropping (figure 18-20) can be used in all conditions along with contour tillage.
As in contour tillage, guidelines are needed to plow for strip-cropping.
Where strip-cropping cannot halt erosion, terraces may be built (figure 18-23).
For the P factor, use the contour tillage or strip-cropping value.
Contour tillage, contour strip-cropping, and terraces are effective ways to slow runoff.

This system can be called contour tree buffer strips, strip-cropping with trees, or bioterracing, because a combination of trees and grass replaces terraces, grass strips, or other means of soil erosion control on hillsides of highly erodible land.
Five different systems were compared: contour tree buffer strips, terracing, conventional tillage, contour strip-cropping, and the Conservation Reserve Program (CRP).
The conservation practice of contour strip-cropping consists of strips of small grains or meadow alternated with strips of rowcrop.
In this study, four contour strip-cropping regimes were analyzed: corn/hay/soybean, corn/pasture/soybean, corn-pasture with legume/soybean, and corn/oats/soybean.
These increased yields in rowcrops not only increase annual cash flows but also give alternatives with a rowcrop component a higher economic return (Table 3), so that terraces become economically feasible at medium and high land values, contour tree buffer strips improve economically as land value rises, and contour strip-cropping becomes the economically best practice at the high land value.
