AE486: Agricultural Management Options for Climate Variability and Change: Conservation Tillage

Figure 4. Percent increase in cotton and corn yields (for the 10 years from 1986-1995, and the 10 years from 1996-2005, compared to the first 10 years of the “Old Rotation,” from 1896-1905) of four treatments under conservation (strip tillage) and conventional tillage. Note the significantly greater yield increases for conservation tillage treatments.
