Testing to determine whether a source of water will be suitable for irrigation water.
About this Testing
Irrigation water is becoming increasingly important in parts of New Zealand, particularly on the east coast of the South Island where rainfall can be scarce. Because irrigation water often has significant levels of dissolved salts, it can have a detrimental effect not only on the irrigated soil, but also on the pumping equipment used. It is therefore important to test the water in order that any issues may be anticipated and the productivity of irrigated land and associated water resources maintained. Guidelines for Irrigation water quality can be found in the ANZECC guidelines. These guidelines cover a wide variety of analytes, therefore we have selected the most appropriate for the irrigation water testing.
Testing covered by our Irrigation Water profile:
Free Carbon dioxide
Langelier Saturation Index (LSI)
Electrical Conductivity (EC)
Approx Total dissolved Salts
Sodium Adsorption Ratio (SAR)
Taking a Sample
Request an Irrigation Water Kit from the Laboratory. It contains 2 sample containers which are all required for one test, i.e. they should all be filled from the same sampling point. If you require microbe testing please consult us.
