DAY FOUR - Thursday, November 17, 2022


7:00am Field Tour Of Imperial Valley, CA This is one of the most fascinating agricultural areas in the world, and November will feature an active field season. Imperial Valley is a significant producer of winter vegetables, seeds for planting, fruit and nut crops, durum wheat for pasta production, dairy and livestock, alfalfa and grass hays. Discover how the diversity of low- and high-value crops interact to provide sustainable crop production. Products are shipped globally. The excess summer heat, water supply, salinity, and (often) difficult soils, challenge the skills of farmers. They have made it into one of the most productive desert crop production areas of the world, with gravity-fed irrigation systems.
