At Waseca, Minnesota, Glomus aggregatum, G. leptotichum and G. occultum spores were more abundant in soil with a Zea mays history than a Glycine max history, while spores of G. microcarpum exhibited the reciprocal pattern. About 90% of spores recovered at Lamberton, Minnesota, were G. aggregatum and did not vary with crop history, but spores of G. albidum, G. mosseae and G. occultum were more abundant in plots with a corn history. Densities of G. aggregatum spores were negatively correlated with soil pH at Waseca, but were unrelated to pH at Lamberton where mean soil pH was lower. -from Authors
