Agricultural Water Testing
Understanding the quality and composition of water on farm is a critical component to modern farm-system management. Hill Labs offers a variety of agricultural water tests so that you can have all of your on-farm needs met by a single supplier.
The analytes in the livestock drinking water profile and their associated trigger values have been taken from the Australian and New Zealand Guidelines for Fresh and Marine Water Quality (ANZECC), section 4.3 Livestock drinking water quality. The ANZECC guidelines cover a wide variety of chemicals, however we have only included those analytes likely to be of concern.
To assist growers and farmers in meeting NZGAP requirements, Hill Labs offers a convenient NZGAP Test Kit. The test kit includes analysis for the presence of E. coli and Faecal Coliforms in water and includes all of the necessary sample items, as well as a discounted courier ticket. The NZGAP Test is IANZ Accredited and results are provided on a 3 day turnaround time.
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.

Irrigation Water Kits can be requested here. A kit 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.
Use of dairy effluent as a source of nutrients for pasture growth has become commonplace, however frequently farmers have little insight on the nutrient composition of effluent being applied, which will change regularly depending on animal feed inputs. This can result in sub-optimal use of effluent as a resource or over application of other nutrient sources, such as fertiliser. As such, Hill Labs has developed a specific test, the Dairy Effluent Test, for testing effluent composition.
| TEST | TYPICAL CONCENTRATION |
| Total Nitrogen | 0.44 kg/m3 |
| Total Phosphorus | 0.08 |
| Total Potassium | 0.3 |
| Total Calcium | - |
| Total Magnesium | - |
| Total Sodium | - |
