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-
