Patent ID: 11614435

Abstract:
The invention relates to the field of soil analysis, in particular the technical analysis of agricultural or horticultural soils. In particular, the invention relates to a sensor device for in situ soil analysis, to a method for in situ soil analysis, and to a device set up for carrying out the soil analysis method, wherein said device, together and in interaction with one or more of said sensor devices, represents a system for in situ soil analysis. The sensor device has a sensor assembly comprising one or more sensors which are configured individually or cumulatively for the simultaneous in situ measurement of at least two of the following soil properties of a soil to be analyzed and for providing corresponding respective measurement data: (a) impedance spectrum, (b) temperature, (c) absorption spectrum NIR-VIS-UV in a spectral range from NIR (near infrared spectral range) to UV (ultraviolet spectral range), and (d) acidic or basic character, in particular pH value. In this case, the distance between in each case two of the sensors of the sensor assembly, which is defined with respect to the respective measurement variable sensors, does not exceed a value of 10 cm.
