Like its cousin NaCl table salt KCl is a salt and roots that encounter high salt concentrations in the soil can be damaged. But KCl can usually be banded with no negative effect though there have been some reports of lower yields with banded K. Reasons for this are often not clear but are more likely to be due to salt effects than to the chloride itself. As a negatively-charged anion
