Economic and agronomic factors have combined to bring about major changes to cropping systems in Saskatchewan. Crop diversification, with oilseed and pulse crops replacing cereals, is occurring even in the Brown soils of Southwestern Saskatchewan. With diversification comes more agronomic questions, as new management strategies must be developed to cope with problems, such as reduced residue production from non-cereal crops. The use of the 1997 PFRA crop residue and seeding survey data help to establish the link between agricultural diversification and the soil climatic factors influencing this diversification,
along with the effects this could have on the sustainability in different regions of Saskatchewan.
