ow clover will
grow with much vigor in all areas susceptible of cultivation, unless on
certain of the western prairies.

Yellow clover has highest adaptation for calcareous soils. In certain
parts of England it has grown so vigorously on soils rich in lime as
almost to assume the character of a troublesome weed. It will grow well
on all clay loam soils, and reasonably well on stiff clays, the climatic
conditions being suitable. It has greater power to grow on dry soils
than the small white variety.

Since yellow clover is usually grown as an adjunct to permanent
pastures, it can scarcely be called a rotation plant. But, like other
clovers, it enriches the soil, and, therefore, should be followed by
crops that are specially benefited by such enrichment, as, for
instance, the small cereal grains.

Yellow clover when sown is usually sown with other grass mixtures, and
along with grain as a nurse crop; hence, that preparation of the soil
suitable for the nurse crop will also be found suitable for the clover.
It is, moreover, a hardy plant, insomuch that in some instances, if the
seed is scattered over unplowed surfaces, as those of pastures, in the
early spring, a sufficient number of plants will be obtained to
eventually establish the clover through self-seeding.

The seed is usually sown in the early spring, but in mild latitudes it
may also be sown in the early autumn. It may be sown by the same methods
as other clovers. (See page 267.) It is usually sown to provide pasture,
the seed being mixed with that of other pasture plants before being
sown. As the plants, like those of the small white variety, have much
power to increase rather than decrease in pastures, it is not necessary
to sow large quantities of seed, not more usually than 1 pound to the
acre. But should the crops be wanted for seed, then not fewer than 3 to
5 pounds per acre should be sown and without admixture with other
grasses or clovers. When the plants once obtain a footing on congenial
soils, there is usually enough of seed in the soil to make a sufficient
stand of the plants in pastures without sowing any seed, but since the
seed is usually relatively cheap, where an insufficient supply in the
soil is suspected, more or less seed should be sown.

Since the stems of yellow clover plants become tough as the season of
growth becomes considerably advanced, where it forms a considerable
proportion of the pasture the aim should be to graze most heavily
