"The main advantage of improved crop rotations is to assist in maintaining the fertility of the soil and thereby to increase the yields of farm crops. ... On the Dominion Experimental Farms throughout Canada, many trials have been made, over a long period of years, with different kinds of rotations. Most of these rotations in Eastern Canada have been arranged for dairy farming or, to some extent, for mixed farming. A few rotations, however, are also given in this bulletin for farmers who desire to obtain a considerable proportion of their revenue from grain and clover seed." -- p. 3-5. gccst Soil gccst Crop rotation Ripley, P.
