"GRASSGYGLING"  can produce a healthy, deep
rooted, vigorous lawn and help to:

       •reeycte valuable nutrients to the soil;
       • reduce watering requirements;
       tSsave 7 hours per season of yard work;
       tS reduce need for pesticides;
       t/use less fertilizer;
       •protect against thatch buildup;
       sf encourage beneficial organisms to keep soil
         healthy and naturally aerated;
       v* reduce methane gas formation In landfills, an
         leachaie to pollute water.

Making your own valuable compost from leaves an
green plant material can solve most of the yard wasi
problem.

Simply let short grass clippings drop to the soil
instead of raking or bagging.  GRASSCYCLING
saves time ana energy and  recycles  nutrients
back to the lawn.

The average householder  can save 25 to 30
minutes with each mowing and produce a better
lawn by following these expert tips:

Q Use low rates of fertil iz:er in the spring and early
summer, with higher rates applied twice in the fall.
Slow-release fertilizers are best, particularly in the
spring and sumrfier.

Q Keep mower set high. Bluegrass, ryegrassand
fescue should be cut at 3 to 4 inches; zoysia at 2-
1/2 to 3 inches.  Mow frequently. Never remove
more than 1/3 of the grass blade at a time.  Sea-
sonal growth rates require a 5 to 10 day mowing
cycle.

Q Keep mower blades sharp.

Q Use pesticides only as needed, and then only
according to label directions, or use common al-
ternatives.

Q If you are using a professional lawn care serv-
ice, askthemnotto bag your grass (mostservices
prefer to grasscycle).

Q Remember, a quality lawn requires proper
mowing, watering, fertilizing and core aeration.

 Leaf Mulching

 Most leaves can be mulch-mowed by cross mowini
 over them. This breaks much of the leaf structur
 down, allowing it to join the grass clippings at th
 soil line, protecting, adding humus, and returns
 nutrients to soil. GRASSCYCLING and mulct-
 mowing leaves can answer the greatest part c
- yard waste concerns.        -

-------
Composting is a natural way of returning nutrients
and humus to the soil through the biotogical action
of microorganisms - bacteria and fungi - thatdigest
organic materials, breaking them down into hu-
mus and releasing nutrients.
       sting yard waste a! home provides a free
source of valuable, fertilizer and soil conditioner
and saves landfill space.
Grass, leaves, dead plant matter and woody prun-
ings and garden debris may be composted.

Choose a composting unit: 10 feet (1/5 or 1/4 of
a roll) of chicken wire, snowfence, or otherfencing
that can be secured into a cylindrical pen.  (Share
a roll with friends or neighbors.)

No enclosure is needed if space is not a concern.

A bin may be fashioned of wood or old pallets, so
it can be opened at one side, or turning units can
be constructed with bins adjacent to each other.

MOTE: Aeration Is ntetssaiy for rapid odor-fre© de-
composition; therefore, It's advantageous to construct
bint with material that allows a constant air flow.

Forfastcompost-readyinafewweeks-mixabout
three parts of  leaves with one part manure or
grass.and add a small amount of soil for "starter."
Add enough water to keep the mix as moist as a
damp sponge (so a couple of drops can be
squeezed out of a handful).
NOTE: Leaves alone will compost very slowly without
a nitrogen source such as grass or manure, but with
correct moisture and a little soil, they will decompose
enough te be used as mulch in a few weeks.

In adding plants,  cuttings, prunings or woody
waste, material should be choppecfor shredded
as m uch as possible.  Such materials will compost
more slowly (see Woody Wastes).

Decomposing creates heat. Temperature on the
interior of a  unit about 3X3X3 will  rise to 130
degrees or more in as little as three or four days.
When it drops, the pile may be turned, so the outer
layer is on the inside. With the fence enclosure
unit, the easy way is to unfasten or simply lift the
cage off, set it up. again alongside the heap, and
move  the material back into the cage by  the
garden forkful,  fluffing it to achieve maximum
aeration, and checking for moisture level.

If more leaves or plant debris are available, they
can be incorporated at this stage.

Noticeable odor is almost always caused by too
much moisture, too little air, or too much grass in
comparison to leaves or other carbon sources.

Compost is ready when ingredients have broken
down into fine particles, unrecognizable as leaves
or plant matter. It can be mixed with garden soil at
a rate of about one pound per square foot.

NOTE: Kitchen scraps and food wastes (except for
vegetabletrimmlngs)shouldnotbe composted In back-

 In addition to composting and grasscycling, there
 are other things homeowners can do to improve
 the beauty and usefulness of their landscapes
 while reducing energy and water consumption.

 Plant native or locally adapted trees, shrubs and
 ground covers. Wildflowers and native grasses
 can be used to beautify hard- to- maintain hillsides
 and ditches.  Plant trees that provide shade for
 your home and lawn during the hottest part of the
 day.

 available at public libraries or  from  County or
 University extension horticulturists.

 Professional services and other private enter-
 prises are already offering choices to fill the needs
 of those who  wish not to deal with yard wastes
 themselves. Most lawn-care services recommend
 and offer "GRASSCYCLING." Some offer on-site
 composting services as well. Others offer yard
 waste collection for a fee and take the materials to
 large-scale composting sites or deliver it to farms
 for land spreading ana tilling-in.
 The following chart is a guide to more efficient
 composting:
 GRASSGYCLING AND COMPOSTING provide
 .relatively easy answers to yard waste disposal
 problems, but woody, brushy wastes from tree
 trimmings and other sources may challenge the
 imagination.                 ;

 Some businesses are providing chipping or shred-
 ding services to households. Others wilfdo collec-
 tion of woody wastes seasonally or occasionally.
 Shredders are available from tool and equipment
 rentals.

 Neighborhood associations or groups of neigh-
 bors or friends may buy good quality chippers
 cooperatively, or rent suitable equipment for a
 weekend, sharing the cost.
