New nitrogen fixation project!

Phil Robertson, Dan Buckley, and I have received NSF funding to work on associative nitrogen fixation in perennial grasses! We will be using isotopic tracers to determine when nitrogen fixation occurs, estimate N inputs on an annual scale, identify the microbes fixing N, and examine the plant-microbe relationships underlying this process. Looking forward to this exciting, challenging project!
