The Canadian Prairies contain some 37.7 million hectares of developed agricultural land -- certainly an impressive figure. Perhaps because of its immense size, farmers have tended to take their land for granted. This has shown up in farming practices, which for decades have stressed short-tern returns with little thought to the long-term health and maintenance of the land. As a result, prairie soils now face a number of serious threats. Salinity, erosion, organic-matter loss and other problems are affecting millions of hectares, although improvements in agricultural technology have masked many of their effects. In all, the cost is staggering. Prairie farmers will lose an additional $100 million in 1984 as a result of soil degradation. This could represent as much as a 10 per cent drop in net farm income from cash crops. --Introduction [1]. Soil conservation Prairie Provinces. Sols Conservation Provinces des Prairies.
