The goals of this project were to demonstrate to cooperating growers how irrigation and fertilizer management are linked together and how management may prevent water movement below the root zone. More specifically, the objectives were to: establish partnerships with three key growers and discuss fertilizer and irrigation management, determine the position of the water front throughout the growing season, diagnose crop nutritional status, and determine nitrate distribution in the soil profile at the end of the growing season.
