Abstract: This study was accomplished on Espíndula Farm, Santa Maria de Jetibá (ES), with the objective of evaluating the litter and nutrients deposition in areas with different succession stadiums. Two areas were selected with different vegetable coverings, defined as: (SF) Secondary Forest, with about 25 ha of area, corresponding to an old area of cassava cultivation with about 50 years in process of ecological succession and where today there is a secondary forest and an Old Secondary Forest (OSF) corresponding to a forest area that has just been submitted to a selective wood extraction for use of the farm itself. In each one of vegetal areas, approximately 0.1 ha was delimited and in these ten conical collectors were randomized distributed. The litter collections were accomplished monthly from November 2003 to October 2005. After drying, the material was stratified and the total contributed and the contribution of the different fractions, and the nutritious addition were evaluated. It was not verified significant differences among the total of litter deposited among the areas, being the highest production values observed in the summer, 5.70 Mg ha-1 (SF) and 5.73 Mg ha-1(OSF), possibly due to the winds and rain mechanical action. The fraction of higher contribution was the foliar, corresponding to 74.62% for the SF area and 69.46% for the OSF area.
