.".. a must for ecologists and plant and animal agriculturalists, managers, and advisors working in intensively managed sown pastures, particularly in many parts of Europe. It is a fine example of a blending of basic and applied research placed in a format understandable even to producers--one that I would consider handing to many western U.S. ranchers who are highly skeptical about why one would ever want to measure something like ammonia volatilization." --Ecology
