Challenges
The depression and drought of the Dirty Thirties was devastating. This drought resulted in a mass exodus of population from the prairies, as well as new agricultural practices such as soil conservation, and crop rotation.
Soil conservation practices such as crop rotation, cover crops, and windbreaks to name a few were massively developed and set in forth upon recovering from the drought experiences of the dirty thirties. Literally layers and layers of topsoil would be blowing away during this time. Bow River Irrigation Project, Red Deer River Project and the St. Mary Irrigation project of Alberta, were a few of the major projects undertaken by the Prairie Farm Rehabilitation Act (P.F.R.A.) resulting in reservoirs, and distribution systems. A current project is Liming (soil) soil liming at the Land Resource Research Institute. Wheat diseases such as wheat bunt and stinking smut can be successfully treated with a fungicide. Disease of plants and animals can break an agricultural producer. Tuberculosis in animals was an early threat, and cattle needed to be tested, and areas accredited in 1956. The newer disease such as chronic wasting disease or transmissible spongiform encephalopathy (TSE) affects both elk and deer. Elk and deer raising is a pioneer field of domestication, has had a setback with this disease. Mad cow disease in cattle and scrapie of sheep are monitored by the Canadian Food Inspection Agency. The poultry sector was plagued by Pullorum disease, and by controlling the flock via poultry husbandry, this disease has been brought under control.
Plants whose traits can be modified to survive a disease or insect have made inroads into Canadian agricultural practices. Cereal rusts which can destroy the majority of areas seeded to wheat, was controlled in 1938 by breeding strains which were rust-resistant. This strain was successful until around 1950, when again a new variety of rust broke out, and again a new species of wheat called Selkirk was developed which was rust resistant. Biotechnology is the center of new research and regulations affecting agriculture this century.

Famous quotes containing the word challenges:
“A powerful idea communicates some of its strength to him who challenges it.”
—Marcel Proust (1871–1922)
“The approval of the public is to be avoided like the plague. It is absolutely essential to keep the public from entering if one wishes to avoid confusion. I must add that the public must be kept panting in expectation at the gate by a system of challenges and provocations.”
—André Breton (1896–1966)
