You can contact Dr. Ron Morse, Virginia Tech, (donna@vt.edu) for information on no-till farming. "Stubble Over the Soil", by Carlos Crovetto, (published by American Society of Agronomy) is an excellent book on the concepts and proven experiance of no-till. My website below might be of help also. -- http://www2.epix.net/~cmfarm/ Steve Groff Cedar Meadow Farm 679 Hilldale Rd Holtwood PA 17532 Ph. 717-284-5152
