The soybean variety ‘Kent’ was planted at 19 sites representing two soil types located on Maryland's Eastern Peninsula. Routine soil tests including soil organic N were performed and correlated with serological distribution of R. japonicum . Nodule samples reacted with 16 Beltsville antisera with no serogroup occupying more than 20% of the total. Beltsville serogroup 110 was positively correlated with several organic N fractions, soil NH 4 + , and soil NO 3 ‐ for the Sassafras soil. Serogroup 123 showed a positive correlation with soil pH and exchangeable Mg. When the Matapeake soil was considered, serogroup 94 was positively correlated with soil N status much like 110 was for the Sassafras soil.
