Analysis Request – Irrigation Water

Irrigation water refers to water used for agriculture and growing crops. The quality of water used has a direct impact on the plants, effects the soil, the wear of irrigation equipment, as well as, high populations of E. coli may affect the health of the consume. Sources include rivers, lakes, reservoirs, dams and wells.

What?

Irrigation water analysis includes the critical chemical analyses of Electrical conductivity (total salt content), Sodium absorption ratio (sodium hazard) and Boron (an essential micronutrient). Depending on the standard required, Microbiological analyses of Faecal coliforms or E. coli is done to ensure water is free from potential pathogens. Vinlab H2O offers various water packages in line with IPW and Global GAP requirements.

Why?

Irrigation water falls on the actual leaves of the plant and is absorbed into the soil, potentially affecting both the growth and health of your crops. The chemical composition of irrigation water also has an impact on the effectiveness of fertilizers used. It is therefore important to makes sure the water is not harmful to your crop.

How often?

The frequency of irrigation water testing depends on the source of water. Well water should be tested once a year, whereas surface water sources should be tested at least three times a year for chemical and harmful microbiological levels.

When?

Irrigation water should ideally be tested when starting irrigation, mid-season and close to harvest.

Who?

All small and commercial farmers should have their irrigation water tested.
