Of the cropping systems across Canada, the risk of soil erosion by water is greatest under potato production
in central and eastern Canada. In these areas there is intensive tillage and little opportunity to reduce the
intensity through conservation tillage practices (Figure 14.5). The cropping system with the next greatest risk
of erosion is the production of maize and soybeans under conventional tillage; however, there is a significant
opportunity to reduce this erosion risk with conservation tillage. Of all soil landscapes across Canada, the
risk of soil erosion by water is greatest in areas with maximum slopes of 10 percent or more, especially those
located in central and eastern Canada where the risk of water erosion is inherently high due to climate
(Figure 14.5).
