Effect
Increased produce quality
Raiz-Mor treated Creeping bentgrass, cv. SR1119, grown in a golf green had on average 5.1 % less substrate richness for bacterial communities, a 11 % lower visual quality (colour, stand uniformity, percentage of localized dry spot), a 17.7 % higher visual localized dry spot rate, leafs contained 4.1 % more N, 4.5 % more P, 0.6 % more K, 6.9 % more Ca, 5.5 % more Mg, 6.4 % more S, 6.9 % more Zn, 5.3 % less B, 12.8 % less Mn, 48.4 % less Fe and 13.7 % less Cu compared to the untreated control.
