Resumo

Os objetivos deste estudo foram avaliar a deposição de serapilheira ao longo de dois anos e a qualidade nutricional da serapilheira, em função do espaçamento de plantio visando à restauração florestal. Os espaçamentos de plantio 1 × 1; 1,5 × 1,5; 2 × 2 e 3 × 2 m, constituem as unidades amostrais dos tratamentos. No espaçamento 1 × 1 m foi observada a maior deposição de serapilheira, não havendo diferenças entre as unidades dos demais espaçamentos. A fração folha mostrou, em todos os espaçamentos, maior aporte de serapilheira (77%). O maior conteúdo de nutrientes foi observado no espaçamento 1 × 1 m. Em geral, constatou-se a seguinte ordem quanto o conteúdo de nutrientes da serapilheira N > Ca > K > Mg > P.

Palavras-chave

Abstract

The objectives of this study were to evaluate the deposition of litter over two years and the nutritional quality of the litter, depending on the planting space aimed at forest restoration. The planting space 1 × 1, 1.5 × 1.5, 2 × 2 and 3 × 2 m, are the sampling units of the treatments. In 1 × 1 m spacing greater deposition of litter, with no differences between the units other spacings was observed. Leaf fraction showed, in all spacings, greater intake of litter (77%). The higher nutrient content was observed in the 1 × 1 m spacing. In general, was observed the following order as the nutrient content of litter N> Ca> K> Mg> P.

Keywords
