Abstract/Contents:Discusses potential effects of humic acids on greens, stating that "in controlled studies, humic substances have increased root mass...length...and photosynthesis in creeping bentgrass...but similar responses have not been observed in the field...The lack of response on turf in field studies may be attributed to the variabilty and uncontrolled nature of field conditions and the difficulty in isolating the effects of nutrients and other ingredients often included in humic substance products." Presnts studies conducted "to test the effects of organic acids and humic substances on putting greens," at Utah State University. Reports that "in both the laboratory and field studies, the humic substances used in our experiments did not have a substantial effect on the water holding capacity in sand greens."
