York Trial Comments Soil analysis performed by NCDA Agronomic Division. In Soil Description section, % organic matter (%OM) is actually % humic matter. June 7: Grass had been controlled by Select. weed density (#/sq yd): AMAPA, 80; PHBPU, 23. June 30: Grass was still controlled completely. A moderate flush of morningglory, in cotyledonary stage, had come since the layby application. August 6: Any PHBPU rating less than 100% is due to emergence after lay-by Yield of check assumed to be zero; too weedy to harvest.
