Dutchess Land Conservancy’s Earth Matters webinar series is back! The first webinar of the season features none other than Jeff Lowenfels, renowned Alaskan horticulturist. In his Fourth book, Jeff exposes a major advance in our understanding of how the soil food web operates and how you can use this new knowledge to make yourself a better gardener, and an organic one at that! Lowenfels is known as the most humorous speaker on the horticulture speaking circuit. Webinar will run from  6-7:30pm.
