February 2021. Brian Whipker and his team in the Department of Horticultural Science, NC State University, have published these greenhouse hemp nutrition guides:  Nutritional Guides for Greenhouse Hemp

May 2020. These field recommendations for floral hemp were prepared by Dr. Michelle McGinnis, N.C. Department of Agriculture and Consumer Services, Agronomic Division in May 2020 and will be updated as new information is developed. (live links available in the PDFs at the end). Please keep in mind that hemp is a new crop (2017 was the first production year in NC), so very limited research based information is available. We are conducting fertility studies across the state every year and will continue to update this page as that information is made available.
