An Iowa State University research team has received a $1 million grant from the National Science Foundation to continue its work developing transceivers and sensors designed to collect and send data about soil moisture, temperature and nutrient content in farm fields. The sensors would relay data along the grid to a central computer that would record information for researchers or farmers, according to the university. The sensors could help predict crop growth and yield by better management of nutrients and water. The goal is to maximize profits and minimize the environmental impacts of nitrogen runoff. ISU researchers had received about $240,000 from the foundation in 2008 to work on the project.
