Inhaltsangabe

Excerpt from Manures and Fertilizers<br/><br/>Before entering upon the discussion of the subject matter proper it will be well to, brie?y emphasize the importance of increasing or at least maintaining soil fertility, if farming is to be made profitable. Continuous cropping, even on soils of the finest quality, without a concomitant return of plant food and the return of humus-forming material must result in soil impoverishment and decreased crop yields.
