A Practical Guide for Adjusting Fertigation Water pH in Specialty Crop Production

Fruit and vegetable producers have widely adopted fertigation as a common practice. However, achieving optimal nutrient use efficiency and growth of crops requires careful management of the irrigation water’s pH, especially when the water quality exhibits excessive acidity or alkalinity. Adjusting the pH of irrigation water is crucial to meet crop preferences and ensure optimal conditions for growth. Growers frequently encounter challenges in effectively optimizing irrigation water pH. This publication aims to address this issue by providing an overview of adjusting irrigation water pH and offering practical guidelines. The target audiences of this guide are farm/nursery managers, growers, crop advisors, Future Farmers of America (FFA), Extension agents, researchers, students, and others who are interested in crop production.
