Fertilizer For Grass








A fertile soil will make a good sod. A thinner
soil should have a liberal dressing of complete fertilizer at seeding
time, and the formula that has been suggested is excellent for this
purpose. If a succession of timothy hay crops is desired, the problem
of maintaining fertility is wholly changed. The nitrogen supplied by
the clover is soon exhausted, and the timothy sod must be kept thick
and heavy until broken, or the soil will not have its supply of organic
matter maintained. Nitrogen must be supplied freely, and phosphoric
acid and potash must likewise be given the soil. The draft upon the
soil is heavy, and at the same time the effort should be to have a sod
to be broken for corn that will produce a big crop without the use of
any fertilizer. The grass is the natural crop to receive the plant-food
because its roots fill the ground, and the corn should get its food
from the rotting sod, when broken. Station tests have shown that a sod
can be caused to increase in productiveness for several years by means
of annual applications of the right combinations of plant-food in the
early spring. A mixture of 150 pounds of nitrate of soda, 150 pounds of
acid phosphate, and 50 pounds of muriate of potash is excellent. This
gives nearly the same quantity each of nitrogen, phosphoric acid, and
potash, and is near a 7-7-7 fertilizer. The only material change in
relative amounts of plant-food constituents, when compared with a
3-10-6 and 3-8-10 fertilizer, is in the increase of nitrogen, due to
the heavy drafts made by continuous mowings of timothy. This fertilizer
should be used as soon as any green appears in the grass field in the
spring after the year of clover harvest. The large amount of nitrogen
makes this an unprofitable fertilizer for clover, and its use is not
advised until the spring of the year in which timothy will be
harvested.
