be included in the agribusiness sector processing farm products. A recent growth area in agribusiness is the advent of organized farmland investment funds operating on the model of direct land ownership with rental back to farmers as operators. Industry categories According to Agriculture and Agri-Food Canada, these are the classifications of Canadian Agriculture Industries. Agricultural science Agricultural science began developing new styles of farming and strains of wheat and crops so that farming could become a successful venture. Farming methods were developed at places such as Dominion Experimental Farm, Rosthern Experimental Station, and Bell Farm. From 1914 to 1922, the Better Farming Train travelled around rural of Saskatchewan areas educating pioneer farmers. The 1901 census showed 511,100 farms and the number of farms peaked in 1941 at a record 732,800 farms. The industrial revolution modernised the farming industry as mechanized vehicles replaced the oxen ploughed land or the horse-drawn cart. Farms became much larger, and mechanized evolving towards industrial agriculture. Production Farming activities were very labour-intensive before the industrial revolution and the advent of tractors, combines, balers, etc. From the late 19th century to the mid-20th century, a great percentage of the Canadian labour force was engaged in high labour, smaller farming practices. After mechanization, scientific advancement, improved marketing practices farms became more efficient, larger and less labour-intensive. The labour population was freed up and went to industry, government, transportation, trade and finance. Agriculture, stock raising and horticulture employed one-fourth of the Canadian population according to the 1951 census as well as providing products for exports and Canadian manufacturing concerns. Farm equipment The Oliver Chilled Plow, which could cut through the prairie sod, was in use by 1896. Binders which could cut and tie grain for the harvest season and grain elevators for storage were introduced in the late 19th century as well. Plows, tractors, spreaders, combines to name a few are some mechanized implements for the grain crop or horticultural farmer which are labour saving devices. Many Canadian museums such as Reynolds-Alberta Museum will showcase the evolution and variety of farm machinery. Challenges The Great Depression and drought of the Dirty Thirties was devastating. The drought resulted in a mass exodus of population from the prairies, as well as new agricultural practices such as soil conservation, and crop rotation. The use of soil conservation practices such as crop rotation, cover crops, and windbreaks was expanded following the drought experiences
