Resumo
In this work, which was carried out in Esperantina, State of Tocantins, soil fertility parameters
were measured in an area cultivated through agroforestry, subsistence farming and native
tropical vegetation. Soil and litter were collected in rainy and in dry season with 10 replicates.
Nutrient levels were very low in both seasons. Rice and maize cultivation areas presented the
highest levels, possibly due to burn practice and mineral fertilizer residues. Organic matter
levels of SAF were the same as those of native tropical forest vegetation. The litter obtained on
SAF in both seasons contrasts with the low nutrients levels obtained, what could contribute to
the maintenance of the production capacity of the agroecosystem.
