POJIOLOGY The surface tilth may be secured by breaking the top- soil early in spring with a cutaway harrow, gang plow or other surface-working tools. This may not be pos- sible, however, on very heavy lands. The cover-crop adds humus and protects the land from puddling and baking in the winter. If it is a leguminous crop it also adds a store of available nitrogen. It is possible, in many cases, to use cover-crops so freely, particularly of the leguminous kind, that the land becomes too rich in nitrogen and the fruit plants make too heavy growth. Usually the cover-crop is plowed under in spring at the very earliest opportunity in order to save the soil moist- ure. It is by no means the universal practice to use cover-crops on fruit lands, but the idea has come to stay, and the grower may adopt it or not as his judg- ment dictates. In order to facilitate the economical and efficient tillage of fruit lands, it is coming to he the practice to devote the land wholly to the fruits. With plums and pears and some other orchard fruits, it is often allowable to use the land for the first two or three years for annual crops, but these crops should gradu- ally diminish and every caution should be taken that they do not interfere with the care of the trees. Apple orchards, when the spaces are 40 feet apart, may be cropped for six or eight years without injury, providing good tillage and other efficient treatment are given. One reason for allowing orchards to stand in sod in the old times was that it was difficult to plow beneath full-grown trees. Those persons who desired to plow and till their orchards, therefore, advocated very high pruning. The diffic
