Abstract
We compared the vertical distribution (0-25 cm) of arbuscular mycorrhi zae, extraradical hyphae, and glomalean spores at grain-filling of cor n under conventional tillage versus no tillage. Root colonization, tot al hyphae density, and spore density were correlated, and were highest at a depth of 0-15 cm in soil. Tillage significantly reduced total hy pha density and spore density at 0-5 cm depth, but did not affect root colonization. Plowing below 15 cm is likely to diminish AM fungus ino cula in the rooting zone of establishing seedlings.
