Method and system for disinfecting irrigation water in agricultural irrigation systems

This invention describes a method for disinfecting agricultural irrigation water across an entire farm system. It works by continuously adding chlorine to the water and then checking a distant point in the field to ensure enough chlorine reaches that far. If the chlorine level isn't sufficient at that outer point, the amount of chlorine being added is adjusted to ensure disinfection throughout the whole system. The claims specifically detail a method involving identifying an "outer field point" and using a variable chlorine source.
