The Nitrogen and Irrigation Initiative

The Nitrogen and Irrigation Initiative (NII) improves nitrogen and irrigation management in California by closing gaps in information access and training. We offer trainings, technical assistance, and on-farm consultations to growers in the San Joaquin Valley and Central Coast. The program is a collaboration of the California Department of Food and Agriculture, University of California Agriculture and Natural Resources, and the University of California, Davis.
