Corn with full soil treatments averaged 97.0 bushels an acre in three year continuous test. Com in rotation with red clover, plus lime and a starter fertilizer averaged aver-aged only 76 bushels. In another test, wheat yielded 30 bushels. Wheat grown in rotation made only 15.3 bushels. But rotation is still important Yields jumped to 111.8 bushela when corn in rotation got a full fertilizer treatment that gave the crop all the balanced nutrients 11 needed for the entire growing season. sea-son.
