Urea/Adblue Storage & Handling, Best Practice

This FISA Information Leaflet is based on a Tilhill Forestry Toolbox Talk.

Urea has been used in the forest industry for over 35 years to treat stumps against the fungal butt rot Heterobasidion annosum (formerly Fomes annosus).  The solution usually contains a blue dye to indicate which stumps have been treated and is a 37% w/v of urea.
