"Bury-and-forget" sensors to decrease fertilizer drainage and runoff

biosensors in farm fieldME's Jonathan Claussen is leading a research team working on a group of "bury-and-forget" soil sensors and remote, wireless data-collection networks that could help reduce the fertilizer content in farm fields.
Data collected by the system will help the engineers build better models of the interactions of fertilizer, soil and crops. This tool could help farmers use less fertilizer in their fields, decreasing runoff.
"If we had a better predictive model, we could have better remedies for farmers. A better model could tell them they can use less fertilizer," said Claussen.
