VIS-NIRSoil profile survey and analysis system

Soil profile EC (conductivity), compaction and OM (organic matter) investigation, soil core collection and hyperspectral imaging analysis

VIS-NIRThe soil profile physical and chemical property survey system consists of a visible light near-infrared spectrometer, a vehicle mounted soil core drilling sampling device, and is equipped with a soil conductivity sensor. Through GPS positioning and data processing surveying software, high-density automatic sampling and measurement of soil reflectance spectra and soil conductivity of different soil profiles within the region can be carried out, and distribution maps can be drawn. This can comprehensively analyze and reflect the carbon and nitrogen distribution, compactness, texture, salinity, water holding capacity, cation exchange capacity (CEC) of the soil profile. It can be used in fields such as soil survey and mapping, soil carbon sink assessment, carbon sink agriculture (soil carbon storage estimation), land reclamation monitoring, and precision agriculture research demonstration.

The system uses a dual band spectrometer with wavelengths of 660nm and 940nm, which comprehensively reflects the spectral characteristics of soil; It can simultaneously measure soil profile spectral characteristics, soil profile electrical conductivity distribution, and soil compaction (drilling resistance sensor), used for mapping soil profile carbon and nitrogen distribution, soil organic matter distribution, soil texture distribution, and other soil physicochemical properties; The supporting software is used for regulation, data recording and standardization, and data processing and analysis.

At the same time, the system can also be used as a soil profile core sampling tool. Users can bring the collected soil cores back to the laboratory for further analysis. It is recommended to choose the SpectraScan hyperspectral imaging analysis technology solution from Yiketai Company.
