Benefits of Conservation Management Practices
headline bar

For 28 years (1942-1969) several small watersheds were operated in a four-year rotation of corn-wheat-meadow-meadow. On some watersheds this common rotational practice was implemented with prevailing cultural practices of moldboard plowing, straight rows, and limited fertility. On other watersheds improved practices were used. These practices included rows planted on the contour, strip cropping, improved plant varieties, and improved fertility. One of the main conclusions during this period was that the improved practices caused less than one third the soil loss of the prevailing practices (1.2 vs 4.1 Mg/ha annually). This provides strong justification for the use of best management practices to reduce erosion.
