In this subregion of southern Alberta and southwestern Saskatchewan, crop and forage production is sustained by irrigation that depends on runoff from the Rocky Mountains and Cypress Hills. Irrigation is the major water use in Alberta and Saskatchewan, with Alberta having almost two-thirds of Canada's irrigated land. North of the prairie and aspen parkland, vegetation shifts to mixed and coniferous forest — there are about 97 million hectares of forest in the Prairies.
The boreal plains are now once again the new frontier, with large oil and gas reserves, nearly all the commercial forestry, expanding farmland in northern Alberta, and hydroelectric power plants in Manitoba and Saskatchewan. The Aboriginal peoples of this ecozone are tied to a traditional way of life, with wildlife a particularly valuable resource. Frontier resource development, particularly mining, is the backbone of the economy. Cree and Dene First Nations account for most of the population. The remaining four ecozones are on the margins of the Prairies and account for small portions of the area and population.
The productivity of the 'taiga' forest is limited by the cooler climate and shorter growing season. The Taiga Shield Ecozone extends across Canada's subarctic, including the northern reaches of Manitoba and Saskatchewan and a small part of northeastern Alberta. Like the Boreal Shield, it is rich in mineral resources and supports the traditional livelihood of the Cree and Dene First Nations. Churchill is an important seaport and railway terminus.
The dominant economic activities are cattle ranching and outdoor recreation. Much of the area is designated as national and provincial parks and protected areas. Resource extraction, coal mining, forestry, and oil and gas production are increasingly in conflict with ecological and watershed conservation. Mountain snowpacks and glaciers of the Cordillera are the source of most of the river flow and water supply across the southern Prairies.

Managing whole systems and landscapes. Sustainable farms treat uncultivated or less intensively cultivated areas, such as riparian buffers or prairie strips, as integral to the farm—valued for their role in controlling erosion, reducing nutrient runoff, and supporting pollinators and other biodiversity. A key theme connecting many of these practices is diversification. Breeding research programs have dwindled in recent years, leaving farmers increasingly reliant on a limited set of varieties tailored to the needs of industrial farms.
Toward this end, UCS has coordinated a statement, signed by over scientists and other experts , calling for increased public investment in agroecological research. The most recent versions of the Farm Bill have included provisions to support more organic farming, to make it easier for fruit and vegetable farmers to qualify for crop insurance , and to help farmers adopt more sustainable practices on their own working lands.
But if we want to see sustainable farming become the dominant model in the US, we need to go much further. UCS has published a series of reports and issue briefs that offer recommendations for promoting sustainable agriculture through farm policy, as part of our overall goal of transforming our food system to provide healthy, affordable, fairly and sustainably produced food for all Americans. We encourage you to take a look—and then contact your representatives to ask them to support sustainable agriculture.
Floods and droughts in farm country do billions of dollars in damage every year. Farmers can reduce that damage by building healthier soils. Shifting Iowa's dominant two-crop farming system toward a more diverse crop mix can be a win-win for farmers and the environment. The public pays twice for US farm policy: once to subsidize outdated industrial farming practices, then again to fix the resulting problems.
We can do better. The science of agroecology can transform the way we grow our food in a more sustainable direction. So why are we investing so little in it? Classical breeding—the practice of improving crop varieties by selectively breeding the best-performing plants—can help farmers in a variety of ways, and public support for breeding research is a smart investment. We can transform the U. Control of damping-off diseases of seedling cotton is important in yield and mechanical harvest.
Tests with a large number of commercial fungicides show seed or within-furrow treatment helps assure dense stands of vigorous plants. Corn breeding research is aimed at developing inbred lines which will perform well in hybrid combinations in Central Texas. The testing program includes dent corn hybrids, single crosses and preliminary tests. Personnel from this station also supervise various types of corn performance tests at Holland, Plano and McGregor. Dent corn hybrids which have performed best over several years include Texas 28 and 30, which have yellow grain and Texas 17W, an early maturing hybrid with white grain.

Popcorn and sweet corn tests also are grown. Sweet corn must have considerable resistance to earworms. Calumet appears outstanding. Production experiments have been conducted to study the effect of certain cropping system-treatment combinations on the yields of corn.
Definite responses to nitrogen, rotation, plant spacing, irrigation and heat have been established.
