Soil data
In the first inventory of each site, soil surface samples (20 cm of depth) were collected in each plot. Following the protocol by theEmpresa Brasileira de Pesquisa Agropecuária (EMBRAPA, 1997) the following soil attributes were obtained: pH in water (pH), phosphorus (mg/cm³) (P), potassium (mg/cm³) (K), calcium (cmol/dm³) (Ca), magnesium (cmol/dm³) (Mg), aluminum (cmol/dm³) (Al), soil organic matter (dag/kg) (SOM), sand percentage (dag/kg) (sand %), silt percentage (dag/kg) (silt %) and clay percentage (dag/kg) (clay %). We calculated the means of each soil variable for each site. Hereafter, sand % will be used as a proxy for soil texture.
