The invention relates to a method for the automatic irrigation of plants, wherein the temporal progression of soil moisture is determined from measured soil moisture values, and said progression is used for the calculation of an optimized irrigation time duration, such that both water excess in the soil and soil drying are avoided as much as possible. Preferably, the time duration of irrigation is constantly evaluated and optimized using comparisons of measured values with prespecified moisture- and dryness threshold values (GWmoist, GWdry), and automatically adjusted to changing environmental conditions and/or plant requirements.

Method and apparatus for the automatic regulation of the irrigation of plants

A mobile apparatus and a process for adequately irrigating soil, wherein the apparatus has an irrigation unit for irrigating soil and a mobile microwave measurement unit for determining the water content of the soil along a measurement path. A control unit is used to irrigate the soil along the measurement path depending on the measured water content. The apparatus preferably also has a water tank and leaves an area of soil to be irrigated autonomously.
