Welcome to soil photometry’s documentation!¶
Just ideas and stuff that’s been worked out
Goals¶
The sensor should be able to detect the following attributes:
- % water
- % air (N2, O2, CO2)
- pH
- CEC
- % SOM, SOC
- % N
- % P
- % K
- Fe+
- Ca+
Notes¶
The ICRAF database can be opened and exported to TXT with this: https://www.netzwelt.de/software-download/18341-mdb-viewer-plus.html
Question about soil pH values¶
Question
The database gives two values for soil pH for some locations: PHH2O, PHKCL. The question is: what is the relationship between these two? Becasue when plotted they don’t correlate well.
