On-the-spot soil testing with newly-developed, affordable field kit
Researchers at the University of Maryland and Columbia University have developed SoilDoc, a new soil testing kit designed to test for the availability of nitrogen, phosphorus, sulphur, and potassium, as well as active organic matter and certain soil physical limitations. SoilDoc is lightweight enough to be used by extension agents to help them make on-farm nutrient recommendations. The raw results of the tests are sent by mobile phone to a central website where calculations are made; tailored fertiliser and organic input recommendations (following the Integrated Soil Fertility Management (ISFM) approach) are delivered back to the extension agent within minutes.
