<![CDATA[Distribution of Arbuscular Mycorrhiza in and Around Surakarta Area. The present study aimed to observe the distribution of Arbuscular Mycorrhiza (AM) in and around Surakarta, including upland and lowland with different types of soils (Vertisol, Entisol, Andisol, Alfisol, Histosol, Fluvisol) and plants. The observation covered the number of AM spore per 100 g of soil and the infection of AM in the plant root samples. The factors of land conditions and plant types determined the results of survey in elucidating the existence of AM. Among 11 locations, the only one location of Vertisol upland in Kentingan campus area did not show the existence of AM. Different spore types from different plant rhizosfer were found in 3 fields: Fluvisol upland in Ngringo, Karanganyar, Andisol upland in Tengaran, Semarang, and Entisol rainfed lowland in Penggung, Klaten. From the other 7 fields with soil types of Vertisol, Entisol, Alfisol and Histosol were obtained AM spores with the same types which originated either from the same or the different plant rhizosfer. The number of AM spore per 100 g of soil and the infection intensity of AM in plant root from all the observed fields were low, indicating that inoculation treatment of infective and effective AM strains to the fields is needed. Key words: Arbuscular Mycorrhiza, distribution, Surakarta area, spores, mycorizal infection]]>
