The objective of this study was to quantify the deposition and nutrients input by litter in the fragment of Seasonal Deciduous Forest, in Itaara, Rio Grande do Sul state, Brazil. Thirty circular metal collectors were allocated in six plots. The deposited material in this structure was separated in leaves, identified by species, fine branches (diameter autumn>winter>summer. The nutrients input follow the order: N>Ca>K>Mg>S>P (macronutrients) and Fe>Mn>B>Zn>Cu (micronutrients). The higher nutrient depositions by litter was Parapiptadenia rigida, following of Ocotea pulchella and Matayba elaeagnoides.
