A smartphone-mediated system for soil organic carbon detection


Suresh Balpande


The soil health is decided on the basis of primary and secondary elements. The primary elements includes Nitrogen
(N), Phosphorous (P), and Potassium (K). In addition, soil pH, conductivity and organic carbon (OC) are also used
to estimate soil health and suitability for specic land use. Soil testing is often conducted to state soil nutrients
recommendations to attain higher crop yields. However, traditional soil testing methods is time-consuming,
laborious and resource intensive. Smartphones are nearly ubiquitous and oer a ready capability for providing
point-of-care testing facility. An attempt has been made to quantify soil OC contents using smartphone camera
as a portable re
ectometer, database of 114 samples and machine learning algorithm. An android application
has been developed to convert colour space into nutrients concentration i.e. relating test strips color to the
concentration of soil OC. It was employed to analyze soil samples encompasses a wide range of organic carbon in
the range of 0.47 - 0.84 % with an accuracy ranging from 85 % to 97%.
