The effect of soil zinc amendments on nodulation, vesicular-arbuscular mycorrhizae, and ozone sensitivity of pinto bean was studied. Zinc amendments of 45 and 135 µg/g decreased both nodulation and mycorrhizae when compared to levels in nonamended soil. Ozone sensitivity of plants increased as available soil zinc increased.
