Graph showing changes in cropland tillage based on data from Statistics Canada, Census of Agriculture, in 5 year increments from 1991 to 2016. The trends show a steady decrease in the area of cropland under tillage where residue is incorporated into the soil, an increase in area where residue remains on the surface, and an increase in no-till or zero-till seeding from 1991 until 2016. In 2016, there is a reversal in the trends with a small increase in area where residue is incorporated, and a small decrease in no-till.
