ingly reduced.

On the average upland prairie soil, alsike clover does not grow so
vigorously as the medium red. The less of density that these possess
under ordinary conditions, the less suitable are they to the needs of
this plant, but when ample moisture is present, good crops may be grown
on much of the soil in prairie areas.

Soils lowest in adaptation to the growth of alsike include infertile
sands and gravels, and the vegetable soils of the prairie so light that
when cultivated they lift more or less with the wind. On such soils the
growth of alsike is short and feeble, and any lack of moisture renders
it increasingly so.

This plant not only requires much moisture to insure the most vigorous
growth, but it is also able to thrive under conditions of soil
saturation such as some of the useful forage plants could not endure.
When the weather is cool, it may be covered with shallow water for
several days in succession without apparent injury. The possession of
this characteristic makes it possible to grow alsike clover in sloughs
not yet drained, but which are dry certain portions of the year.

=Place in the Rotation.=--Much of what has been said about the place for
medium red clover in the rotation may also apply to alsike clover. (See
page 70.) On upland soils its place in the rotation will be very similar
to that of the other variety, but with the difference that the rotations
will be longer, because of the perennial habit of growth in the alsike.
It will be best sown, therefore, on clean land which has produced a crop
that has been cultivated the previous year. Consequently, it may follow
such crops as corn, potatoes, field roots and beans in the North, and
the same crops in the South, with the addition of cow peas, soy beans
and the non-saccharine sorghums. But it may be sown after other crops
when necessary, especially when it is to be pastured. One chief
objection to sowing it thus for hay is that the hay will be less free
from weeds.

On upland this crop may be followed with any kind of a crop requiring
much nitrogen. No crops can be made to follow it with more advantage,
however, than corn and the sorghums, or potatoes. Rape will feed
ravenously on the overturned sod, and wheat and the other small grains
will also feed similarly.

On low lands, especially when they partake of the nature of sloughs, the
rotation is different. In some instances alsike may follow the natural
grasses produced by the slou
