The association of soil environments and sporulation of arbuscular mycorrhizae was investigated using pot cultures. Increased arbuscular mycorrhizal spores as well as the better growth of the host plants were observed when sorghum (Sorghum bicolor) was treated with different soil conditions using several fertilizers with different concentrations. For to five fold increase of sporulation of arbuscular mycorrhizae was noticed depending on the mycorrhizal species. Although there were some differences between the four arbuscular mycorrhizae species and the conditions of soil environments, maximum populations of spores were reached at about 30-40 days after cultivation. The populations of four arbuscular mycorrhizal species was individually fluctuated. Also, the growth rate of host plants were different from the fertilizers over 2-3 times, but the increase of spores were not influenced by it.
