The Effects of Potassium Chloride to Counteract the Negative Effects of Side-banded Urea on Plant Establishment

A series of experiments to determine if adding KCl to side-banded urea would increase the safety to the seedlings against the toxic effects of side banded urea, regardless of the separation between the seed and fertilizer. No significant effect was observed, although there was one site-year observed where addition of KCL with urea in the side-banded urea for flax was beneficial.
