Belowground component and soil data for a tropical savanna following invasion by Urochloa brizantha, Cerrado region, Brazil, 2022.

dcterms:description "This dataset contains measurements of aboveground biomass, belowground organ biomass, belowground bud bank density, root biomass, soil fertility, and soil carbon and nitrogen stocks from invaded and non-invaded vegetation patches of a tropical savanna (Cerrado). Sampling was conducted in an area invaded by Urochloa brizantha, where invaded and non-invaded patches were paired, totaling 10 patches with 2 plots each. The study site is located within the Estação Ecológica de Itirapina, a natural reserve in southeastern Brazil, spanning the municipalities of Brotas and Itirapina, São Paulo State. Data were collected during a field campaign in November 2022. The dataset was generated to assess the effects of the invasive grass Urochloa brizantha on the belowground components of open Cerrado ecosystems, with a focus on the bud bank, biomass allocation among belowground organs, and soil properties." ;

rdfs:label "Aboveground biomass was collected in 0.25 m2 plots and sorted by growth form, invasive and non-invasive, and dead material. Belowground biomass was sampled from the same plots to 30 cm depth, and organs were washed, classified by type, and live buds counted under a stereomicroscope. Roots and soil samples were collected with a 5 cm auger every 10 cm down to 1 m depth. Soil samples were analysed at ESALQ/USP for chemical fertility and total C and N. Biomass samples were oven-dried (80 degrees) to constant weight and expressed in g/m2. Bud density was expressed as buds/m2. Soil C and N stocks were derived from bulk density and concentration data. All data were checked for transcription errors, unit consistency, and laboratory quality control."
