Résumé
An important aim of organic production is to improve overall soil health. Arbuscular mycorrhizal
fungi (AMF) form symbiotic relationships with the roots of host plants in which plants directly
receive nutrients. AMF also are reported to indirectly promote plant health through their
contribution to soil building. Thriving AMF communities increase the water-holding capacity of
soils through the deposition of proteins. This project sought to determine whether the genetic
variances between popular cultivars of carrot would promote the growth of different AMF
communities over the growing season, thereby altering the quantity of AMF-associated proteins
in soils. There were no obvious trends toward increases in AMF-associated soil proteins that
correlated to any cultivar of carrot. Most sites had moderate changes in protein quantities from
spring to fall, with no clear pattern. One site (Larryville) had consistently increased Fall
quantities of AMF-associated proteins compared to Spring quantities for all cultivars for both
years (2017 and 2018). We observed more intensive weed management at this site. Storm related
challenges impacted some farms during these years, with flooding inflicting considerable carrot
losses at multiple sites.
