Basic information about water hardness and pH-value
Especially for treatments with trace elements and fertiliser additions,
attention must be paid to the water hardness and the pH-value to
ensure clean surfaces and smooth functioning of all valves.
At a water hardness greater than 15° dH (German water hardness),
we recommend the use of polyphosphate-based hardness stabilisers.
When complying with the manufacturer specifications, the products
are safe for health and the environment.
Product example: Folmar P30 from Aquakorin.
Particularly with crop protection product mixtures with trace elements
such as boron, which increase the pH-value, the pH-value of the
ready-to-use spray liquid should be kept below </= 7.
Product example:

Citric acid

Acidifying agents, such as:

pH-Fix from Sudau

Spray Plus from Belchim Crop Protection

X-Change from De Sangosse
Commercial sprayer cleaning agents are strongly alkaline and there-
fore neutralise crop protection product residues such as sulphonylu-
rea in the sprayer. In case of limescale in the implement, however,
they increase the pH-value and are therefore counterproductive for
descaling.
