Irrigation - Overview
One effective way to reduce costs linked to irrigation is to irrigate only when required, by tracking the amount of water that has been applied and monitoring the soil moisture. Several solutions are available on the market, such as tensiometers, capacitance sensors and time domain transmission.
Irrigation scheduling can also reduce costs. For example, avoid irrigating in windy conditions as much as possible as this requires a greater application rate. Irrigation at night is preferable as there is less evaporation and the electricity rate may be cheaper. Also avoid irrigating during milking – especially if the electricity account has a peak demand component (TOU metering).
The kind of equipment used and the way the irrigation system is designed and maintained influences the overall efficiency of the irrigation system and thus has an impact on running cost.
Often irrigation systems have their own electricity account; in some region dedicated irrigation line charges and/or special tariff structure are available and are much more advantageous than standard pricing structure, your electricity account manager is the best placed to advise you on the best option available in your region for your irrigation system.
