Many scientists have studied agricultural soil change. Most of these studies focus on
changes in the surface 0 to 30 cm soil. Despite a whole body of scientific research that
shows that soils change on relatively short time scales under different management regimes,
classical pedological theory states that we should expect these changes to occur only in the
surface few centimeters and that they are not of adequate magnitude to suggest
fundamental changes in pedon character over short periods of time. Nevertheless, when we …
