Soil Profile Modification for Increasing Crop Production

  • H. V. Eck
  • P. W. Unger
Part of the Advances in Soil Science book series (SOIL, volume 1)


Burnett (1969) stated that any tillage operation which alters any part of the soil profile can be considered as a form of soil profile modification. However, profile modification generally means some form of tillage, with or without chemical or physical amendments, to depths greater than ordinary plowing (Unger, 1979). In this review, our discussion will be restricted to profile modification to depths of 0.25 m or more. Some examples are plowing, subsoiling, vertical mulching, completely disrupting and mixing the profile, trenching, and installation of subsurface barriers.
