Residues in soils : a gas chromatography - mass spectrometry study

Combined gas chromatography and mass spectrometry has been used to identify unknown residues in soils (especially pesticides). The effect of U.V. light on DDT and linuron and quantitative estimation of elemental sulfur in different soils has also been carried out.

Ontario Federation of Agriculture records, 1974-1984

The Ontario Federation of Agriculture was established in 1936 and is the largest voluntary farm organization in Canada, representing 37,000 farm families. The Federation came about in response to the creation of the Canadian Chamber of Agriculture (later renamed the Canadian Federation of Agriculture) in 1935. The establishment of an Ontario branch was needed to provide a forum through which similar organizations from other provinces could communicate about farm issues that were of interprovincial, national, or international importance. The organization is led by farmers and is based in Guleph, Ontario. Their missionis to enable prosperous and sustainable farms. They accomplish this through lobbying, government and media relations, and community representation.
