Long-term Tillage Plots


The Triplett-Van Doren no-tillage research plots were established in 1962 to determine how much, if any, tillage was needed to obtain satisfactory crop yields. Since the establishment of the plots, the conservation movement in agriculture has increased. Between 35-40% of cropland in the United States consisting of eight major crops is now no-till. We have maintained the no-till research plots to continue to address relevant research questions in conservation agriculture concerning tillage. This research is conducted at two sites in Ohio: Wooster (Snyder Farm) and Hoytville (Northwest Research Station). We study tillage (no-till, chisel, and moldboard plow) and crop rotations (continuous corn, corn-soybean, and corn-oat-hay). 

Advantages of No-till 

  • Reduced runoff and erosion
  • Improved soil water storage
  • Requires less energy, time, and labor
  • Increased carbon storage
  • Improved soil health
More than 70 publications have resulted from the research done in the no-till plots. A summary of published studies from these sites can be found here.
