Why does drip irrigation save water

Rose and Shrub Kit: Use this kit with Shrubblers to water individual plants, shrubs or containers. Soil type is another factor that will determine what type of emitters you will need. There are three main types of soil: clay, loam and sand. Clay absorbs water slowly, causing it to spread on the surface and form a roughly inverted cone shape below ground. For that reason, watering slowly with a 0. It is smart to amend the soil by digging in loamy or sandy soil to mix with the clay.

Loam absorbs water at an even rate, forming an evenly wide pattern below ground. A half-gallon to one GPH emitter is best with natural loam, organic compost or bagged soils. Sand absorbs water quickly in an almost straight-down pattern. If you use a drip emitter, a two GPH flow of water from a dripper is best. Often it helps to use a mini-sprayer to provide water for a wide root pattern in this situation.

The use of a timer at the start of your irrigation system is a must. If you would like to set up a drip system to save yourself time so you can take off for the weekend or a vacation, a timer is key. A timer will give your plants the steady, consistent watering they need for optimum health and growth. Battery Timers: These will fit the needs of most home garden situations.

Used most often for shrubs and trees, bubblers have higher discharge rates and shorter watering cycles. Because bubblers can operate at high pressures, they are particularly useful for conversion from conventional sprinkler to low-volume systems. When low-volume overhead irrigation is desired, micro-spray is best for ground covers, and plants such as ferns, which prefer some humidity.

Dripperline is the fastest growing and easiest to install type of drip irrigation. For watering closely spaced plants, hedges, vegetable gardens, etc. Other applications include planter boxes and rings for large pots, as well as containers and loops around large trees.

Ideal for watering hanging baskets and for creating humidity, misters are normally used in the inverted position and spray downwards. A growing application of misters is for outdoor cooling, where the immediate evaporation of mist can dramatically reduce the air temperature. Subsurface irrigation works better in heavy clay or sand conditions than overhead sprinkler systems. Loam, which contains equal proportions of sand, silt and clay, is ideal. However, plants can thrive in a very broad spectrum of soil textures when subsurface watering is applied at the proper rate, with appropriate spacing.

A newly built home in Jacksonville, Fla. Using a single system for both plant and turf areas resulted in excessive overspray and very long run times. NDS irrigation experts reviewed the existing system, and the total system flow flows from all spray and rotor nozzles and their respective run times was using gallons per minute. A better, more efficient irrigation was needed. NDS technicians designed a new system to convert the turf areas to subsurface dripperline irrigation system, and the landscaped areas to on-surface drip irrigation.

How much energy savings could this add up to? To better understand potential savings, the NRCS provides a helpful Energy Estimator Tool to get you started on your journey to lowering energy usage for irrigation.

Using this tool, we can run through an example for a switch from sprinkler irrigation with a diesel pump to drip irrigation with a more efficient, electric pump.

Let's look at a 5 acre crop of sweet corn planted in Union County. While there are certainly benefits to using drip irrigation systems, there are a few disadvantages to consider.

Regular maintenance and close management will be required to ensure that the system is working properly and is not damaged or leaking. Finally, it might be beneficial to add drip irrigation to a high value crop midseason if the weather dries out, but this adds a more time-intensive step to suppling adequate irrigation compared to more traditional systems.

Installing a low-pressure, water-efficient, drip irrigation system, can significantly reduce energy costs. Let's Stay Connected.
