Just as spring gives way to the heat of summer every year, Russell Ranch hosts a field day to highlight research on sustainable farming. This year's field day theme was Nitrogen, Water and Climate Change. The field day took place on May 31, 2012 and featured field presentations, workshop breakout sessions and a growers' panel with A.G. Kawamura, Tony Turkovich, Don Bransford and moderated by Tim Hartz. The growers' panel spoke to the difficulties that California's farmers may face with upcoming regulations on climate change and nitrate in groundwater.
Over 160 people attended, including farmers, policy-makers, scientists and students. Attendees learned about greenhouse gas emissions from agriculture, nitrates in drinking water, California’s new carbon market and soil microbial communities. Researchers from UC Davis and the company PureSense presented the results of research on a novel method for determining local, crop-specific water demand levels in real time to improve irrigation scheduling.
