The extension program covers the areas of Precision Agriculture (PA), Grain and Small Grain Crops Agronomic Management, and Climate Variability and Change. I utilize modern extension methods, which include participatory approaches of farmers training their peers, establishment and use of learning networks to facilitate and promote engagement between extension faculty, agents and practitioners, co-development (with farmers and extension agents) of extension materials and trainings, and the use of digital outlets such as social media, webinars, videos, and iBooks for information transfer. The goals of my program are: 1) to increase field corn and wheat yield, profitability and input use efficiency by providing farmers with applied research-based information and training on the implementation of the most effective site-specific agronomic management practices; 2) to increase climate science literacy, raise awareness and demonstrate the use of climate forecasting as an agronomic management tool; 3) and to increase overall knowledge, adoption, and skills on the use of PA technologies and associated management strategies. The areas covered by this extension program are essential to ensure not only sustainable food security but also for ensuring increased environmental stewardship and productivity. The adoption of PA technologies as a result of this extension program has contributed to the increase of input use, energy and fuel efficiency on Alabama farms.
