Agroforestry systems as an ecological approach in the Brazilian Amazon development

Agroforestry systems as an ecological approach in the Brazilian Amazon development

Forest Ecology and Management 45(1-4): 319-323

This paper discusses EMBRAPA's agroforestry systems experience in the Brazilian Amazon. The forestry species and fruit trees introduced in shifting cultivation systems had great success, particularly the wood-producing species Cordia goeldiana and Swietenia macrophylla and the fruit trees Musa spp. and Theobroma grandiflorum. In forestry plantations, Vigna unguiculata was mixed with the trees C. goeldiana, Jacaranda copaia and Bagassa guianensis in the first two years to reduce costs of investment and cultural treatment. In this case, Vigna unguiculata did not affect survival of trees and increased tree height and diameter growth. The introduction of wood-producing trees in livestock pastures can represent formation of a system more balanced and stable through nutrient cycling than is possible today. A silvopastoral system has been carried out in the Paragominas region (eastern Para) using the forestry species Eucalyptus tereticornis, B. guianensis and Schizolobium amazonicum, the crop Zea mays and the forage species Branchiaria brizantha, B. humidicola and Panicum maximum. Performance of the forestry and forage species has been satisfactory and the corn yield was more than the regional average. The cattle, at a low stocking rate, graze normally on the site and cause no harm to the planted trees.
