APPARATUSES AND METHODS FOR IN SITU SOIL ANALYSIS Russian patent published in 2021 - IPC G01N21/31 G01N27/22 G01N33/24 

FIELD: testing.

SUBSTANCE: invention relates to the field of soil analysis, in particular, to technical analysis of agricultural or garden soils. In particular, the invention relates to a sensor apparatus for in situ soil analysis, a method for in situ soil analysis, and an apparatus configured to perform the method for soil analysis, wherein said apparatus in combination and in interaction with one or more said sensor apparatuses constitutes a system for in situ soil analysis. The sensor apparatus comprises a sensor unit containing one or more sensors configured individually or jointly to simultaneously measure in situ at least two of the following properties of the soil subject to analysis and to provide the corresponding measurement data: (a) the impedance spectrum, (b) the temperature, (c) the NIR-VIS-UV absorption spectrum in the spectral range from NIR (near infrared spectral region) to UV (ultraviolet spectral region), and (d) acidic or alkaline nature, in particular, the pH value. The distance between, in each case, two sensors of the sensor unit therein, determined relative to the corresponding sensors of the measured variable, does not exceed the value of 10 cm.

EFFECT: provided improved apparatuses and methods for in situ soil analysis.
