To build up and maintain fertility in the soil, feed a large part of the crops and return the manure to the land. If manure is not available, plow under crops grown for the purpose. Plow deep (but do not subsoil). Grow leguminous crops for the nitrogen they add to the soil. Commercial fertilizers and lime may be important means of improving the soil, but the fertilizer requirements of different soils and different crops in different seasons are so little understood that we are not yet in a position to make positive recommendations that are of a general application.

"The codling moth or apple worm and the apple scab have no direct relationship except that both attack the apple and are, respectively, the chief insect enemy and the chief fungous disease of this fruit. Both are, however, subject to practical control by sprays, which being necessary at the same dates, in the main, can be combined in single applications, and it is for this reason that they are considered together in this bulletin. A brief life history is given of the codling moth, with a description of the sprays and other remedies for it, followed by similar matter on the apple scab. The bulletin concludes with a joint consideration, for both pests, of spraying outfits and methods, with directions for the combination of the spray mixtures, and a spray calendar" -- introduction.
