Irrigation Audits – Fact Based Irrigation Management


Properly done irrigation audits (in compliance with standards recommended with the Irrigation Association) collect numerous data a great irrigation system. While all of this data provide insight concerning the status from the irrigation system, you will discover two dimensions or information of especially high importance inside an irrigation audit. Each one of these information are determined within an irrigation valve or station level and be a consequence of the amount of water collected in each catch can.

One of these brilliant dimensions inside an irrigation audit is distribution uniformity or DU. Essentially, DU is only a value that signifies how evenly or unevenly water can be used for the landscape. Unevenly distributed water results in either wet spots or dry spots. However, this is not always visually apparent and so the DU might be the methods through which this problem are available.

The second of individuals irrigation audit dimensions is precipitation rate. This value measures the amount of water applied per unit of your energy that is usually calculated in inches hourly or centimeters hourly. As stated inside an earlier article, it is essential that the size of the problem cans are the same. This could make certain that the great, solid precipitation rate can be discovered. While confirmed station could have a handful of dozen catch cans, the precipitation rate calculated is essentially the normal precipitation rate for the entire station.

The value of the precipitation rate inside an irrigation audit is at how a precipitation rate comes even close to the type of soil that water is distributed around. How quickly water is distributed around the ground would depend about the type of soil. Some soils readily consume water while other styles absorb water a lot more progressively.

Once the precipitation rates are calculated for that station and also the type of soil is known for your same station, the irrigation audit will condition the your clients how that certain station irrigation needs to be setup to make sure that water can be used in a way that allows it absorb into the soil. Unsure this may result in a station flowing water too extended for your soil to consider and water simply puddling or running off initially. That’s wasted water.

However, some soils require a longer sustained utilization of water to have the ability to sufficiently penetrate the soil surface and get the primary zone in the grass or shrubbery. Not carrying this out is an additional, but less apparent, way water is wasted. Water can be used but instead than running off it gets into the soil but that is it. It does not attain the best goal in the plant roots.

An irrigation audit tries to remove as much subjectivity and uncertainty as you can in organizing an irrigation system. Taking a chance might be the most popular method that irrigation agendas are often setup. However, a very done irrigation audit comes with an opportunity for particulars to dictate an irrigation schedule instead of vague recommendations.
