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

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.
