1. A method for controlling irrigation, the method comprising:
- irrigating a soil area with water during an irrigation event utilizing a plurality of valves, each of the plurality of valves in flow communication with a water source and a sprinkler;
monitoring a moisture content of the soil area utilizing a wireless sensor for each of the plurality of valves, the wireless sensor in wireless communication with a wireless controller, wherein monitoring a moisture content of the soil area is performed a plurality of times each day;
determining if the soil moisture content value exceeds a predetermined threshold; and
limiting the irrigation event if the soil moisture content value exceeds the predetermined threshold, wherein irrigation event is a daily scheduled irrigation event and limiting the irrigation event is limiting the scheduled irrigation event for a single day.
