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.

1. A mobile apparatus for irrigating soil according to requirements, comprising: an irrigation unit for irrigating the soil,a mobile microwave measuring unit for determining water content of the soil along a measuring path, andwherein, by the aid of a control unit, the soil is irrigated using the irrigation unit in accordance with the water content along the measuring path measured using the mobile microwave measuring unit. 2. The apparatus as claimed in claim 1, wherein the mobile microwave measuring unit comprises at least one microwave source and a microwave detector provided at a distance from the microwave source. 3. The apparatus as claimed in claim 1, further comprising a water tank. 4. The apparatus as claimed in claim 1, further comprising a high-pressure device for the pressurized delivery of at least one water jet in the direction of the ground. 5. The apparatus as claimed in claim 4, wherein water is delivered through at least one injector with an injector diameter of 1 to 5 mm. 6. The apparatus as claimed in claim 1, wherein water is delivered through injectors, and a number of injectors are provided at regular intervals over the circumference of a pipe and the injectors comprise outlet openings which are at an angle to a longitudinal axis of the injectors. 7. The apparatus as claimed in claim 1, further comprising a color sensor for establishing a grassy or bare area of ground. 8. A method for irrigating soil according to requirements, comprising the steps of: making a mobile determination of the water content of soil along a measuring path by using microwave radiation, andirrigating a region of the ground in accordance with the measured water content of the soil along the measuring path. 9. The method as claimed in claim 8, wherein the path traveled along is predetermined or self-determined in such a way that all the regions of ground are irrigated according to requirements. 10. The method as claimed in claim 9, wherein, to determine the water content of the soil, a depth profile of the water content of the soil is determined by absorption measurement and reflection measurement of microwaves. 11. The method as claimed in claim 8, wherein water carried along in a mobile water tank is used for irrigation and, when the water in the water tank or the energy in the mobile measuring device reaches or goes below a minimum amount, a correspondingly set-up docking station is automatically traveled to for recharging with water and/or energy. 12. The method as claimed in claim 8, wherein irrigation is performed with at least one water jet directed toward the ground. 13. The method as claimed in claim 12, wherein the at least one water jet is directed toward the ground under high pressure in a pressure range from 2 to 40 bar. 14. The method as claimed in claim 12, wherein the at least one water jet is introduced directly into the soil by the aid of an injector at least partially inserted in the ground. 15. A mobile car for determining water content of soil along a measuring path, the mobile car comprising a microwave measuring unit structured and configured to emit microwave energy into the soil for determining the water content of the soil along the measuring path. 16. The mobile car according to claim 15, wherein the mobile car is an automatically travelling car. 17. The mobile car according to claim 15, wherein the microwave measuring unit comprises at least one microwave source and a microwave detector at a distance from the microwave source. 18. The mobile car according to claim 15, wherein the mobile car is structured and configured for travelling on predetermined tracks. 19. The mobile car according to claim 15, wherein the mobile car is structured and configured for travelling on self-defined tracks in an area to be irrigated. 20. The mobile car according to claim 15, wherein the mobile car is structured and configured for continuously measuring the soil moisture along the measuring path. 21. The mobile car according to claim 15, wherein the mobile car is structured and configured for measuring the soil moisture along the measuring path at intervals. 22. The mobile car according to claim 15, wherein the mobile car is structured and configured for assigning determined water contents of the soil to position coordinates along the measuring path for recording a moisture map. 23. The mobile car according to claim 15, wherein the mobile car is free of an irrigation device and free of a tank for water for irrigation. 24. A method for determining water content of soil along a measuring path, the method comprising using a mobile car including a microwave measuring unit structured and configured to emit microwave energy into the soil for determining the water content of the soil along the measuring path by microwave radiation. 25. The method according to claim 24, comprising: determining the water content of the soil along the measuring path using the mobile car;assigning determined water contents of the soil to position coordinates along the measuring path; andrecording a moisture map containing the mutually assigned water contents and position coordinates. 26. An irrigation arrangement comprising a mobile car including a microwave measuring unit structured and configured to emit microwave energy into the soil for determining water content of the soil along a measuring path. 27. The irrigation arrangement of claim 26, wherein an irrigation device of the irrigation arrangement is a mobile irrigation device. 28. The irrigation arrangement of claim 26, wherein an irrigation device of the irrigation arrangement is a fixedly installed irrigation device.
