Resumo1. The Maraca rain forest occurs on sandy soils which have very low concentrations of nutrients, but it has none of the structural features which are often held to be associated with forests on nutrient-poor soils. 2. The present paper reports tests of three hypotheses which were proposed to account for these unexpected features of the Maraca forest: (a) that the forest is unproductive and has a low nutrient demand; (b) that the trees are particularly efficient at withdrawing foliar nutrients before leaf abscission; and (c) that decomposition is rapid and the nutrients are quickly recycled
