Description: This presentation will give the results of a 23 year field study conducted on the Macdonald Campus Farm, Ste. Anne de Bellevue, Quebec. The study was conducted to examine the effects of three different tillage practices, all with and without crop residue, on continuous corn crop yields, and changes in organic matter with time. The treatments were: conventional tillage, conservation tillage, and no-till. Since the crop was continuous corn over the 23 year period, the residue was corn stubble and leaves, placed on the plots immediately after harvest. The plots were 18m wide by 90m long, and all field operations were conducted with farm size machinery. The soil type was a sandy loam. The results showed that tillage type did not have an effect on crop yield, while soil organic matter increased slightly with the no-till + crop residue treatment.
