Conventional and low-input Zea mays L. Merr./Triticum aestivum L. rotations were established in 1988 with tillage treatments ranging from no-till to moldboard plowing. Sampling for vesicular-arbuscular mucorrhizal (VAM) fungi was conducted in octuber, 1992, after a soybean crop, and in May, 1993 during winter wheat reproductive development. Soil cores were removed to a depth of 27 cm and into 9 cm sectins. Spores were isolated from this soil, characterized, and quantified. Field soil was for an infectivity assay in the greenhouse using Paspalum Flugge as host plant. Farming system significatly affected populations of VAM fungi. Soil in low-input agricuture had greater populations of Glomus occultum type group spores and oter Glomus spp., whereas the conventionally farmed soil had greater populations of Glomusoccultum type group spores.. |
