1. A system for irrigation of an area by a plurality of successive adaptive irrigation cycles starting with a first irrigation cycle, the system comprising:

  • an irrigation controller for initiating and stopping irrigation in response to signals, a probe having sensors for detecting arrival of a wetting front, the probe providing signals associated with the detected wetting front depth, a cycler comprising a processor, a memory and an I/O unit, the cycler being coupled to the irrigation controller for emitting signals thereto, and the cycler being coupled to the probe for emitting and for receiving signals therefrom, a computer program preloaded in the memory of the processor and running on the processor, the processor controlling adaptive irrigation and managing successive irrigation cycles, and the computer program comprising;

    a predetermined threshold limit Δ

    R, and a predetermined ratio G1 representing soil texture characteristics.
