The uptake of salts by the roots of roadside trees is a common problem wherever sodium chloride, calcium chloride, and/or magnesium chloride are applied to de-ice highways in the winter or for dust abatement in the summer. Symptoms start as tip burn with the bases of the needles still green. Damage progresses with the continuation of salt application; first terminal growth of branches ceases, eventually followed by mortality.
