Poor water quality can have a significant impact on the efficacy of many products used in spray applications.
However, APAL’s water testing service can provide sprayer operators with the analysis to ensure they are getting the most from their chemical application.
Water testing should be done annually when using bore water, water from streams or rivers, piped ground water or water stored in unlined dams or concrete tanks.
According to the Grains Research and Development Corporation’s spray water quality fact sheet, when considering if the water quality is suitable for a particular product, operators need to have accurate information about what may be present in the water that could affect the products being used.
The starting point should always be an accurate water test from a reputable laboratory and a thorough check of the product label and technical information from the manufacturer.
Tips for water sampling
Correct sampling is imperative to ensure accurate analysis and interpretation. Precise management can only occur with a quality representative sample.
