dc.description.abstractIn the recent years, low input agriculture has gained high popularity and there is an emerging body of literature on the role of arbuscular mycorrhizal fungi in organic farming and its potential use in low input agriculture systems. This study was conducted to analyse mycorrhizal status of several 31 different plants in organically managed farms in south Florida: organic farm at the Florida International University and the organic fruit, farm Possum Trot. Rhizosphere soil was analysed for mycorrhizal spores and soil nutrients, and plant roots were analysed for mycorrhizal colonization status. Possum Trot, which is a less disturbed site, had higher mycorrhizal spore density in the soil as compared to the organic farm at the Florida International University, which gets highly disturbed with student activities. However, plants at the Florida International University organic farm had higher degree of mycorrhizal colonization in the roots. Of the 31-plant species analysed, Cymbopogen nardus had highest root colonization (75%), while Spinacia oleracea had no signs of mycorhrizal colonization in the roots. Surprisingly, although very low, arbuscular mycorrhizal colonization was observed in roots of Eruca sativa and Chrysophyllum cainito which are normally reported as non-host plants of mycorrhizal fungi. Arbuscular mycorrhizal spore density showed a negative correlation with soil N, while it had a positive correlation with soil P. Though spores of Glomus, Gigaspora, Acaulospora and Scutellospora were found in our study. Glomus were the dominant genera in the rhizosphere of plants grown in the organic farms. Our results indicate that disturbance did not have much impact on the mycorrhizal colonization in the roots, but did have an impact on the rhizosphere spore density. The high occurrence of mycorrhizal fungi in the organic farms of south Florida and potential for the use in organic farm management is discussed.en_US
