Irrigation Water

Irrigation water can be tested where a problem with salinity is suspected. Growers who would also like to check the plant nutrient content of their water or pinpoint a specific element which may be causing a toxicity problem due to excessive levels can also benefit from an irrigation water analysis. This service is not intended for assessing water for drinking purposes.
