Research

My research focuses on N cycling in livestock-cropping systems. Current efforts are directed at

1) improving N cycling and use in pastures;

2) reducing nitrate loading of surface and ground water;

3) testing the concept of phytofiltration to clean nitrate-contaminated ground water;

4) assessing the tolerance of different alfalfas to pollutants and stresses;

5) developing ways to select improved alfalfa germplasm to meet environmental goals; and

6) evaluating alfalfa germplasm for biomass and biofuel uses.
