Yield Shield touted as paradigm shift in canola farming
McCrea describes Yield Shield as a breakthrough in agriculture after trials in Europe and North America. Rourke of Ag Quest tested canola plots with a 2x4, yielding higher quality crops. Ag Shield licensed Rourke's patent in 1999 and produced prototypes quickly. The method keeps canola alive, avoids wind damage, allows early or late pushing, and cuts swathing costs. South and North Dakota farmers report higher yields and oil content, with strong interest from seed companies and producers seeking economical gains.
