Definition – What is drip irrigation?
What is drip irrigation?-Drip irrigation is a methodology of controlled irrigation within which water is slowly delivered to the root system of multiple plants. in this methodology, water is either dripped onto the soil surface on top of the roots or directly to the root zone. It’s usually a technique chosen over surface irrigation as a result of it helps to cut back water evaporation.
Drip irrigation, which is additionally generally mentioned as micro-irrigation or trickle irrigation, consists of a network of pipes, tube valves, and emitters.
Drip irrigation is outlined as any watering system that delivers a slow-moving supply of water at a gradual rate on to the soil.
Is the practice of applying tiny amounts of water and fertilizer uniformly across a selected space. The water and fertilizer area unit delivered directly to the crop root zone, eliminating runoff, evaporation, and drift.
A properly designed and managed drip irrigation system provides producers the most effective uniformity and application efficiency offered, consequently saving them time, energy, and water, all whereas maximizing yields.
Typical sprinkler systems unit, on average, regarding seventy-fifth water efficient, whereas drip irrigation systems have ninetieth or higher water potency. This could be attributable to several key style variations.
A high-pressure sprinkler sprays frequently deliver too much water too fast to be absorbed by the soil, and are also prone to wind-dispersal. Because the water can’t be absorbed, it either puddles, which can be unhealthy for plants, or it runs off and is wasted.
The slow delivery rate of drip irrigation allows the soil to absorb the water laterally, and maintain a uniform moisture level. The direct delivery of water to the soil additionally removes the chance of wind spreading.
The increasing popularity of conservation, environmental friendliness, and also the green movement has created drip irrigation a classy selection; however, it’s a sound possibility for increasing plant health and saving cash, as well.
Drip systems are pretty simple to style and install, as they do not need any trench digging and also the above-ground tube may be simply conformed to a variety of landscapes. This makes them an excellent possibility for avid do-it-yourselfers, and putting in the system yourself can save a substantial amount of cash.
Overall, drip irrigation could be a nice choice, whether or not your goal is environmental and economic conservation, plant health, style simplicity, or all of the above.
There are two main types of drip irrigation systems – surface and sub-surface.
A surface drip irrigation system
Uses close emitter spacing (12”-18”) and little wall (8-10 mil) drip line injected 1” to 6” below the surface. These systems are usually referred to as “temporary” as a result of the drip line is retrieved and recycled yearly. The sub mains may be permanent or temporary. These systems are generally used on high price crops as a result of the yearly expense of new drip line and therefore the labor for installation.
Surface irrigation is a technique that covering a whole field with water. Irrigation wets the plants but produces runoff. In contrast, drip irrigation may be a way more controlled irrigation technique. It works by exposing the roots to a direct supply of water.
This technique is facilitated by the use of drip emitters that release water in a very slow and steady fashion. Drip emitters are little — just about the size of 1 / 4 — and are set on the ground, usually organized in rows. Drip emitters are connected to facility water by a hose. There is Another version of drip irrigation uses a hose that has drip emitters designed into it. This variation on the drip irrigation technique is named trickle tape.
A subsurface drip irrigation system
The water is applied to the root system. this sort is used particularly in growing row crops.
A subsurface drip irrigation (SDI) system uses 20” – 27” emitter spacing and a slightly thicker wall (13-15mil) drip line injected 8” – 14” below the surface. These systems area unit permanent, creating style and installation crucial to make sure longevity. SDI systems are primarily used in row crop agriculture, however, are creating their way into some high-value crops.
