Fertilidade do solo sob sistemas de produção de subsistência, agrofloresta e vegetação remanescente em Esperantina Tocantins

Abstract

RESUMO Estudo em Esperantina (TO) quantificou os atributos da fertilidade do solo em área cultivada sob sistema agroflorestal (SAF), mata nativa e lavoura de subsistência. O solo e a serapilheira foram coletados no período chuvoso e no período seco, com 10 repetições. Os teores de nutrientes nas duas épocas foram muito baixos, sendo maiores no solo cultivado com arroz e milho em função da queimada e resíduos de adubação mineral. Os teores de matéria orgânica no SAF se equipararam aos da mata. A serapilheira encontrada no SAF nas duas épocas contrasta com os baixos níveis de nutrientes, podendo contribuir para a manutenção da capacidade produtiva do agroecossistema.
