Grains and field crops
In early 1975 a magnetic devise for treating cereal seed was imported into Western Australia from Canada, The device ("Zapper" Magnetic Seed Treater, manufactured by Agronetics Ltd., Calgary, Alberta, Canada.) consists of two parallel magnets with opposed poles, encased in a plastic moulding. Seed is treated by passing it through the magnetic field between the magnets. Literature accompanying the Zapper claimed earlier maturity and that - "...a majority of research tests have shown 5 - 15% increases in yield", The device was tested in five field trials and in laboratory tests during 1975. No effect of magnetic treatment was detected in any trial. 75M41, 75MT35, 75WH61.
