| Lawns do more than make your yard look good.
Lawns absorb water, which helps reduce storm runoff and improve water quality. Lawns also have a significant cooling effect, provide oxygen, trap dust and dirt, promote healthful micro-organisms, prevent erosion and filter rainwater contaminants. And most importantly, lawns are where people and pets can play outside the house.
|Lawn care, however, has come at a high cost to the environment. According to the U.S. National Wildlife Federation:|
Much of the environmental cost associated with lawn care can be avoided.
The only way to reduce a dependence on chemical fertilizers is to develop a healthy lawn, which is naturally resistant to weeds, insects and diseases. If you need to fertilize your lawn more than once a year, consider these ways of improving the natural health of your lawn:
Improve the Soil
The first step is to test the soil's pH - it should read between 6.5 and 7.0, which is slightly acidic. Soil that is too acidic will need a sprinkling of lime; sulfur can be added to soil which is not acidic enough. You can buy a pH tester (see below, this page) for $40 - $60. Another solution is to have your soil tested professionally; first call your extension office - they often provide soil testing as a free service.
Lawns grow best in loamy soils that have a mix of clay, silt and sand. Too much clay in the soil mix, or heavy use, can compact the soil and prevent air and nutrient flow. Compacted soil may need aeration, a process of lifting small plugs of turf to create air spaces in the soil. For best results, rent an aerator or hire a lawn service to do the job - this will remove "finger size" plugs which improves aeration. Aeration is best done before top dressing and fertilizing.
Organic matter, such as compost and grass clippings, will benefit any type of soil; it lightens soil which is heavy in clay, and it builds humus in sandy soils, which helps retain water and nutrients. Some lawn mowers are equipped with mulching attachments which break up the clippings and disperse them as you mow.
Choose a Locally Adapted Grass
Grasses vary in the type of climate they prefer, the amount of water and nutrients required, shade tolerance and the degree of wear they can withstand. Ask your local garden center to recommend grass which is best adapted to your area.
3. Mow Often, but Not Too Short
Giving your lawn a "Marine cut" is not doing it a favor. Surface roots become exposed, the soil dries out faster and surface aeration is reduced. As a general rule, don't cut off more than one-third of the grass at any one time. Most turf grass species are healthiest when kept between 2.5 and 3.5" tall.
When the lawn is finished growing for the season, cut it a bit shorter to about 2". This will minimize the risk of mold buildup during winter.
4. Water Deeply but Not Too Often
Thorough watering encourages your lawn to develop deep root systems which make the lawn hardier and more drought-resistant. Let the lawn dry out before re-watering; as a rule of thumb, the color should dull and footprints should stay compressed for more than a few seconds. When watering, put a cup in the sprinkler zone; it should get at least one inch (2.5cm) water. Most healthy lawns require only 1" of water per week.
The best time for watering is early morning - less water will be lost to evaporation. Ideally, it's better to water the first half-inch or so, then wait for an hour or two before watering the second half-inch.
5. Control Thatch Build-Up
Thatch is the accumulation of above-soil runners, propagated by the grass. This layer should be about 1/2" ( 1.25cm) on a healthy lawn, and kept in balance by natural decomposition, earthworms and microorganisms. Too much thatch prevents water and nutrients from reaching the grass roots. Before resorting to renting a dethatcher, however, effort should be made to improve aeration to control thatch buildup. Aeration brings microorganisms to the surface that will eat most of the thatch. If you don't aerate, the roots stay near the surface, contributing to thatch buildup. When you aerate once a year it breaks down the thatch, allowing the roots to get deeper in the soil. This leads to thicker grass which naturally kills weeds too. While a dethatcher will reduce thatch buildup, it can strip and thin the grass so much it reduces competition for weeds allowing them to germinate easier. You can also reduce thatch with a steel rake.
for different grass types
How long can you wait between waterings before the lawn starts to go brown?
12 - 21 days: Bahia grass, Buffalo gass, Bermuda grass, St. Augustine grass, Centipede grass
8 - 12 days: Carpet grass, Fine fescue, Kikuyu grass, Seashore paspalum, Tall fescue, Zoysia
5 - 7 days: Ryegrass, Kentucky bluegrass, Bentgrass
The fine-leaved fescues (grass blades) as well as the "common" types of Kentucky bluegrasses, such as Park and Kenblue, require less water, fertilizer and cutting than turf-type perennial ryegrass or many of the newer "improved" types of Kentucky bluegrass.

'next-generation' reel lawn mowers
Times have changed.
Push mowers (reel mowers) used to be heavy, clunky contraptions which required great effort in cutting the lawn.
A new generation of reel mowers has been designed, however, which operate much more effectively with a fraction of the effort.
The added benefits include a good light exercise and quiet, pollution-free lawn care. Consider the advantages of a reel mower:
Reel mowers shear the grass rather than tearing it.
Most rotary mowers tear the grass which leaves the tips shredded, and the
tips soon turn brown. A sheared cut gives a greener lawn, and is preferred
by lawn care professionals.
Quiet. You can cut the lawn anytime without disturbing the neighbors or the wildlife. Listen to the birds as you cut the lawn!
Non-polluting. The savings in fuel is significant to both the environment and your wallet. No more dead spark plugs, messy oil changes or stored fuel.
Easier. Today's reel mowers are lighter, easier to push and more effective than the old push mowers. The light weight also makes it easier to move from front to back yard, or lift into a pickup.
Low maintenance. Aside from the occassional drop of oil and blade sharpening, there's little maintenance required. Some models have blades made of hardened steel which do not require sharpening. These blades will last up to ten years before needing replacement.
Inexpensive. With prices ranging from $100 to $350, the cost of a reel mower is less than half that of a lower-end power mower.
you have a small to medium size lawn, switching from a gas mower to a reel
mower may be the biggest environmental savings you can make from your home.
If your lawn is large, you can use a reel mower for small or isolated sections,
or for a helper to use. Whenever your reel mower is being used, the result
is cleaner air.

Lawns and Golf Courses
Large lawns, and especially golf courses, require large amount of herbicides and chemical fertilizers to maintain their condition and appearance. The impact on the environment is considerable.
Recent experiments using organic compost have shown this method to be very promising. Generally, researchers and practitioners recognize that incorporating high-quality compost does several things:
1. Adds food and nutrients for plants and organisms,
2. Adds a diversity of organisms to the soil,
3. Encourages plant growth promoting substances in soils.
