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.
