SOUTIHERN WIS. CHElSEMAKERS' & DAIRYMEN'S ASS'N. 77 In grain farming the nitrogen must be maintained by growing legume crops, such as clover, the stock peas, the soybeans, the vetches, an(l the alfalfas, and plowing them Mll(ler, and Oy returning the crop residues, as corn stalks, oats, an(l wheat straw, and possibly by growing leg-mile catch crol)s. In live-stock farmi-ng the manures must be depen(le(l upon largely to provide the nitrogen and humus. No mat- ter, though, which so stem is followed, it is far from an easy matter to maintain the nitrogen and humus in the soil and farmers should not be led to believe that a mere rotation of crops will (lo it; or that even the growing of clover will (lo it if the clover is not left on the land. Where only the pro(luce of the farm is depended upon it is easier for the grain farmer to maintain the supply of nitrogen and humus than it is for the live-stock farmer. From the t tanrdpoint of maintaining the phosphorus content of the soil, the live-stock farmer has the advan- tage, and of the various classes of live-stock farmers, the dairyinan has the greatest advantatge, because less of the phosphorus is sold from the farm in dairy products than in ineat and bones. Many dlairymen, in fact most of them, buy a large part of their feed, especially the concentrates as bran and oil meal. Where this is done on an extensive enuglgh scale and the manure carefully saved and applied to the lan(, all of the elements of plantfood may be provided for in suf- ficient (quantities for large crops. It should, however, be the ambition of every dairyman to grow on his own farm all of the feed for his cows. This can b. done, too, if proper methods are adopted so that clover and alfalfa can be grown successfully. It is now known that ton for ton, well cured alfalfa hay is about as valuable as bran for feeding dairy cattle. It is also known now that alfalfa can be grown on any land in Illinois or Wisconsin that will grow corn successfully. It will usually be necessary to give the land special attention to get the alfalfa start-
