Abstract

Biomass and Nutrient input by Allagoptera arenariain in Restinga da Marambaia, Rio de Janeiro, RJ. This research assessed the amount of organic matter and foliar nutrients in the soil from Allagoptera arenaria in a Palmae shrub community of Restinga da Marambaia, Rio de Janeiro. Samples were collected at ten randomly demarcated plots of 10 x 10m (100 m²) in the bush. We collected three (3) leaves of ten randomly chosen adults. It was possible to quantify an annual increase of dry mass of 8,2 Mg ha-1 yr-1 for the focused area. We observed for N an average grade of 12,3 g kg-1 followed by 5,7 g kg-1 for K, which respectively represent an investment of 303 kg N ha-1 year-1 and 140 kg K ha-1 year-1. We observed for P mean levels in leaf material in order of 0,31 g kg-1 with intake of 7,4kg ha-1 year-1.

Keywords: Nutrient cycling; coastal ecosystems; palms; nurse plants.
