Termites for Nitrogen?

“Termites have bacteria in their stomachs that fix nitrogen,” says no-till consultant Bill Crabtree. “A CSIRO study found that having termites in a crop gave yield benefits by keeping open pores in the soil, reducing compaction and nutrient cycling. In the Geraldton area a guy who has been no-tilling for about 20 years sprayed out the termites in the field. By taking the termites out he found quite significant yield reductions happened a couple of years later.”
