More Sustainable Strawberry Production

Strawberry field

A team of researchers from North Carolina State University set out to provide strawberry growers with information that could help them transition to more sustainable soil and pest management production practices. Their study, published in HortTechnology, compares conventional, compost and organic strawberry production systems in the southeastern United States, and revealed good news for growers. All three systems resulted in positive net returns, and two showed “considerable reductions” in negative environmental and human health impacts.

According to the authors, the nonfumigated compost system and organic system resulted in reductions in negative environmental and human health impacts measured by a set of indicators. “For example, the total number of lethal doses (LD50) applied per acre from all chemicals used in each system and measuring acute human risk associated with each system declined from 118,000 doses per acre in the conventional system to 6,649 doses/acre in the compost system and to 0 doses per acre in the organic system,” the authors explained. “Chronic human health risk, groundwater pollution risk, and fertilizer use declined as well in the compost and organic systems as compared with the conventional system.”
