The soil test kit challenge presents a need for better information on soils from around the world to help people grow crops & aid in research. Better soil information helps to grow food more accurately on potentially valuable land that is currently unused. Information can be crowdsourced and disseminated using simple solutions including affordable sensors and mobile devices.
The People of the Soil aims to leverage a small, cheap, disposable device to collect soil data, send these to a database via a web app or SMS. The data can be retrieved from the web app and SMS.
