Serapilheira acumulada em complexo rupestre de granito, Mimoso do sul, ES

Abstract

This study aimed to quantify the biomass, content of nutrients in accumulated litter, correlating with rainfall and temperature. Sampling was conducted in five transects (50m x 2m), collected with a template (0.25 m x 0.25 m) from May 2011 to April 2012. Fraction was separated in “other species” (a mixture of leaves, twigs, flowers, fruits of various species), and “pseudobombax” (material of the Pseudobombax aff. campestre). A completely randomized design was used with twelve treatments and five replications for biomass; for contents: twelve treatments and three replications. The Pearson correlation between the attributes of biomass with rainfall and temperature was performed and its significance was tested. The accumulated average was 8,900 kg ha-1, distributed throughout the year, N, Ca and Fe were the nutrients with higher accumulation in the litter. Correlation existed between both fractions and climatic variables for macronutrients: N, P and S, and the micronutrients Fe and Cu in fraction “pseudobombax”.
