During ten years of daily newspaper experience, Bill developed a strong interest in agriculture. Research scientists at the University of Saskatchewan and elsewhere found him a reliable interpreter of their findings, with ability to present them in laymanís terms.

In 1941 Bill Bradley moved to The Western Producer as agriculture editor. He built a strong agricultural news section, travelling extensively to cover farm organization activities, including exhibitions and livestock shows and sales. He was promoted to executive editor of The Western Producer in 1948.

He became a director of the Saskatoon Industrial Exhibition in 1945, serving as its president in 1950-51, and also served a year as president of the North Saskatchewan Branch, Agricultural Institute of Canada. He is a member of the Saskatchewan Institute of Agrologists.

Bill left The Western Producer in 1952 to start his own newspaper, The Livestock Times, specializing in the coverage of livestock shows and sales. This newspaper was combined, in 1955, with the Regina-based Saskatchewan Farmer into a new periodical, Farmer & Stockman which was followed, in 1958, by The Westerner. The strong personal following he had among prairie stockmen stood him in good stead during these changes. Each paper served as the official publication of the Saskatchewan %tock Growersí Association and of beef cattle, swine and sheep breedersí groups in Saskatchewan, Alberta and Manitoba; a relationship that lasted until 1988 when The Westerner ceased publication.

Farm Light & Power, a publication reaching most farms in Saskatchewan, Alberta and Manitoba, was established by Bill Bradley in 1959 with the co-operation of electrical utilities serving those farms. It reports the experience of farmers engaged in balanced and specialized agriculture, and advises readers on the safe and wise uses of electric energy. Bill visited hundreds of western farms to produce such articles.
