Solos, Florística e Fitossociologia em Áreas de Reserva sob Vegetação de Cerrado Sensu Stricto em Propriedades Rurais de Urutaí, GO

The aim of this study was to characterize and compare the soil, the floristic composition and structure of two plant communities of cerrado in reserve areas in rural properties in Urutai, GO (R1 and R2). The availability of most soil nutrients is low, both as R1 to R2, however the R1 soil is less chemically poor in nutrients and has a higher content of organic matter than R2. In the reserve area R1 it was recorded 66 species belonging to 27 families. In the area of R2 reserve it was recorded 26 species assigned in 15 families. The floristic similarity between areas was 0.43. The Shannon diversity index (H’) was 3,265 nats.ind-1 in the R1 area and 2,758 nats.ind-1 in R2. The studied reserve areas have distinct vegetation with respect to the species composition and structure. These differences are probably due to soil properties in each community and the influence of anthropogenic factors.
