The more you know, the more you can grow. The AP Moisture Probe also measures soil, or air temperature, in degrees Celsius. The AP Moisture Meter and AP Moisture Probe are powered by one standard 9 volt battery. The AP Moisture Meter has an auto-shutoff feature to save the battery. Timely irrigation is needed to obtain the highest yields and the best possible crop quality.
Tensiometers only measure soil moisture in one spot.
Most other high cost sensors only measure soil moisture in a specific area. There is no way of knowing the moisture condition of the root system unless multiple sensors are used. PolyPro Access Tube, or deeper if you put two or more tubes together. To even come close to getting the same deep moisture profile, you would need 5 or more tensiometers, or other type sensors. To get an accurate soil moisture profile for precision irrigation, you need information from more than one spot at one level.
