Increasing Endomycorrhizal Fungus Inoculum in Forest Nursery Soil with Cover Crops
Abstract:Corn, millet, sudex, and sorghum were all effective cover crops for increasing inoculum density of vesicular-arbuscular fungi (Glomus spp.) in nursery soils. Spore production was increased approximately 7 to 12 times, depending on the cover crop used. Sweetgum seedlings did not differ significantly in size on plots previously planted with any of the four cover crops. Eighty-nine percent of the sweetgum seedlings grown after cover cropping had root-collar diameters exceeding the minimum (0.25 inch) recommended for outplanting of this species.
