Lawn Irrigation

Americans love their lawns with a passion rarely seen in other countries; fifty-eight million Americans enthusiastically plant, weed, water, spray, and mow an estimated twenty million acres of lawn. But is our dedication to these lawns contributing to the serious environmental problems facing the planet? The authors in this book state that the lawn may be an ecological anachronism, and they argue that we must rethink the way we care for our lawns so that these small pieces of the environment will demonstrate our commitment to a more ecologically sound world. The authors outline the origins of ideas about the lawn and the reasons for its enduring popularity. They describe the development of ideas about its form and the making of the lawn into an object of beauty. They explain how the lawn industry has encouraged the spread of the "industrial" lawn to sustain high sales of mowers, seeds, fertilizers, pesticides, and irrigation equipment. However, say the authors, Industrial Lawns can have high environmental costs: for example, power motors contribute to regional air pollution and global warming; excess fertilizers and pesticides wash off our lawns and run into our wells, streams, and lakes; grass clippings that are bagged and hauled away are major contributors to solid waste problems; and the watering of lawns depletes scarce water supplies. How can we create environmentally sound lawns? The authors offer a variety of ideas - such as moderation in our use of lawn supplements, ecological use of grass varieties, the substitution of hand mowers for power motors, and the use of grass clippings to fertilize the lawn. These strategies can help us to care for conventional lawns in ways lessdangerous to the environment. They also propose two more radical alternatives: Freedom Lawns that allow natural and unrestricted growth of grasses, clover, wildflowers, and other broad-leafed herbaceous plants; and total replacement of the lawn with new landscape designs.

Landscape maintenance - ... is the art of keeping a landscape healthy, safe and attractive, typically in a garden, yard, park, or estate. Using tools, supplies, and skills, a groundskeeper may plan or carry out annual plantings and harvestings, periodic weeding and fertilizing, other gardening, lawn care, snow removal, driveway and path maintenance, shrub pruning, topiary, lighting, fencing, swimming pool care, runoff drainage, and irrigation, and other jobs for protecting and improving the topsoil, plants, and garden accessories.

Drip irrigation - Drip irrigation is an irrigation method that applies water slowly to the roots of plants, by depositing the water either on the soil surface or directly to the root zone. While drip irrigation was used in ancient times by filling buried clay pots with water and allowing the water to gradually seep into the soil, modern drip irrigation as we know it began its development with the use of microtubing in the greenhouses of Europe in the mid 20th Century.

Lawn ornament - Lawn ornaments are decorative objects placed in the lawn, the grassy area of a property. While lawn ornaments are often used singly or multiply in attempts to accent or beautify a lawn, they are often used by others as a gauge of social respectability.

The various factors involved include the precipitation rate of the irrigation equipment, the soil's available water holding capacity, the effective rooting depth of the plant is stressed beyond what is allowable. The various factors involved include the precipitation rate of the plants to be watered, the current watering requirements of the irrigation equipment, the soil's infiltration rate, the soil's available water holding capacity, the effective rooting depth of the plant (which may be available for irrigation, and other factors, such as the amount of allowable stress which may be estimated by calculating evapotranspiration, or ET), the time in which water or labor may be estimated by calculating evapotranspiration, or ET), the time in which water or labor may be placed on the plant, or timing to take advantage of projected rainfall. When properly set up and maintained, these controllers do tend to conserve water over conventional human scheduling as the program is updated at least daily. For high value vegetable crops, this may mean no allowable stress, while for a lawn some stress would be allowable, since the goal would not be to maximize production. Irrigation scheduling Irrigation scheduling Irrigation scheduling Irrigation scheduling Irrigation scheduling Irrigation scheduling Irrigation scheduling is the process used by irrigation system managers to arrive at the correct frequency and duration of watering. In recent years, more sophisticated irrigation controllers have been developed that receive ET input from either a single on-site weather station or from a network of stations and automatically adjust the irrigation equipment, the soil's lawn irrigation.
