drip irrigation system |
Utilizing a drip irrigation system involves the installation of a permanent plant watering system that enables the homeowner to place water where it is wanted, and in the exact amount that is necessary for optimum plant growth. Drip irrigation systems range in size from a few plants to several thousand acres, and permits the cultivation of slopes previously thought unusable and land left idle. In fact, the more difficult the installation, the greater the advantages of drip irrigation.
Of all the irrigation methods, drip irrigation is the most efficient. Sprinklers shoot water into the air, where much of the water is lost to evaporation and never reaches the plant. Flood irrigation transports the water in open trenches to the soil where the planting gets about half of the water supplied. Sprinklers are more efficient than flood irrigation, with only about one fourth of the water lost, but drip irrigation results in losses of less than 10 percent of the supply. With the water supply getting lower and lower throughout the country and the world, the conservation of this precious commodity by drip irrigation may eventually be the difference between adequate food and famine, or green yards and dirt.
In short, drip irrigation system is the slow and precise delivery of water to chosen plantings. This is achieved by the use of flexible polyethylene tubing or PVC pipe with devices for dripping water (emitters) and low-volume sprays, drip tape, Laser Soaker Line, or Porous Pipe systems. The systems are easy to install, requiring no trenching and only shears for cutting polyethylene hose or tubing, and PVC pipe cutters for cutting PVC pipe. A hole punch is required for installing an emitter into the polyethylene hose. Drip irrigation can maintain near perfect moisture levels in the root zone of the plants, avoiding the too wet/too dry swings typical of overhead watering. Drip irrigation systems can be controlled manually or by the use of an automatic timer in conjunction with a tensiometer, and can be used to apply fertilizers directly to the roots of plants.
