An ecologist has traced soil’s smell to its microbe community.

It could give smallholder farmers a cheap alternative to costly DNA sequencing for soil testing.

Ecologist Rosa Boone found the volatile compounds fungi and bacteria emit can be captured and analyzed to build an electronic-nose sensor.

EU soil-monitoring rules are due soon, and researchers still must build a working sensor.
