This practical "how-to guide" provides guidance on using conservation tillage under furrow irrigation to growers, crop consultants, and public sector practitioners. This guide incorporates 4 years of field research done near Fort Collins and years of work done on the Western Slope as well as wisdom and experience of local farmers practicing conservation tillage.
