The California Institute for Water Resources focuses on practical, science-backed solutions for water and nutrient management challenges throughout California agriculture. Their Nitrogen Management Training resources provide growers, consultants, and farm managers with educational materials designed to improve fertilizer efficiency while meeting environmental stewardship goals.
The website includes guidance on nutrient budgeting, irrigation management, soil and tissue testing, and best management practices for reducing nitrogen losses. These tools are especially valuable in regions where groundwater quality and water conservation are critical concerns. By improving nitrogen application timing and efficiency, growers can reduce waste, lower input costs, and help preserve natural resources for future generations.
