Researchers at the University of Maryland and Columbia University have developed a new soil testing kit designed to help farmers in third world countries. On-the-spot soil testing could have major impact in improving crop yields due to poor soils. The kit contains battery-operated instruments and safe materials for agricultural extension agents to handle in the field. They can test for the availability of nitrogen, phosphorus, sulfur, and potassium, as well as active organic matter, and certain soil physical limitations. The raw results of the tests are sent by cell phone to a central website. Then, calculations are made and recommendations are delivered back to the extension agent.
