The manufacturing process produces a pellet which is a very bright blue colour and does not bleach, making it easier to see the pellet on the soil for longer.

In the UK, the term ‘RAINPROOF’ was authorised for use on the label.

High and low rainfall events were simulated under laboratory conditions

Doff utilises unique Resin Technology to produce a pellet that has enhanced resistance to rainfall. Trials show that after 7 days under simulated heavy rainfall, it is the most resilient pellet.
