Abstract

Studies were conducted in Ontario on dry bean (Phaseolus vulgaris L.) in 2010 and 2011 using fulvic acid (LX7^®, MTS Environmental Inc.) or humic acid (Plant XL^®, Alpha-Agri) fertilizers. Twenty fulvic acid field trials and 15 humic acid field trials indicate that these fertilizers were ineffective, as plant vigour, height, 100-seed weight, and yield were similar to a control treatment.
