Vegetable Gardens & Organic
Matter

Organic matter improves soil
as a growing medium for plants. It helps release nitrogen,
minerals, and other nutrients for plant use when it
decays. A mulch of partially rotted straw, compost, or
undecomposed crop residue on the soil helps keep the soil
surface from crusting, retards water loss from the soil, and
keeps weeds from growing.Practically any plant material can be
composted for use in the garden. Leaves, old sod, lawn
clippings, straw, and plant refuse from the garden or kitchen
can be used. Often, leaves can be
obtained from neighbors who do not use them or from street
sweepings.
The purpose of composting plant refuse or debris is to decay it
so that it can be easily worked into the soil and will not be
unsightly when used in the garden. Composting material should
be kept moist and supplied with commercial fertilizer,
particularly nitrogen, to make it decay faster and more
thoroughly.
The usual practice in building a compost pile is to accumulate
the organic material in some out-of-the-way place in the
garden. It can be built on open ground or in a bin made of
cinder blocks, rough boards, or wire fence. The sides of the
bin should not be airtight or watertight. A convenient time to
make a compost pile is in the fall when leaves are
plentiful.
In building the compost pile, spread out a layer of plant
refuse about 6 inches deep and add one-half pound or one cupful
of 10-10-10, 10-20-10, or 10-6-4 fertilizer to each 10 square
feet of surface. Then add 1 inch of soil and enough water to
moisten but not soak it. This process is repeated until the
pile is 4 to 5 feet high. Make the top of the pile concave to
catch rainwater.
If alkaline compost is wanted, ground limestone can be spread
in the pile at the same rate as the fertilizer.
The compost pile will not decay rapidly until the weather warms
up in spring and summer. In midsummer, decay can be hastened by
forking over the pile so moisture can get to parts that have
remained dry. The compost should be ready for use by the end of
the first summer.
For a continuing supply of compost, a new pile should be built
every year. Compost can be used as a mulch, or worked into
flower beds and the vegetable garden.
When properly prepared and thoroughly decayed, compost is not
likely to harbor diseases or insects. If the compost is used in
soil where an attempt is made to control plant diseases, or if
it is mixed with soil used for raising seedlings, the soil
should be disinfected with chemicals recommended by your local
Extension agent or State agricultural college.
