RESUMO
Nesse trabalho foram realizadas análises espectroscópicas por ESR da matéria orgânica de solos (gleissolos), do Rio de Janeiro, incluindo avaliações nas macromoléculas de ácido humico, ácido fulvico e humina. O nível de radicais livres semiquinona e a largura de linha das frações humina correlacionaram melhor com o solo inteiro.
