Optimizing Industrial Hemp Production, Dr. Brian B McSpadden Gardener, Ph. D and United Hemp Industries, Kentucky - 2017
"Despite suboptimal growing conditions, Suståne Natural Fertilizers produced extraordinary results. Suståne 3-7-4 applications were selected to increase SOM and porosity, as well as provide sufficient
nutrition in the otherwise P-deficient soils."
"At harvest, hemp plots receiving Suståne 8-2-4 produced significantly higher yields than the untreated control plots. Hemp receiving the low rate of Suståne had marginally higher stalk yields but marginally
lower seed yields than the high rate plots. While both rates were profitable for the grower, the ROI was notably greater for the low rate at this site."
