RESUMO:

Family organic productions systems involved in the Association of Family and/or Organic Farmers of Andradas and Region (Associação dos AgricultoresFamiliares e/ouOrgânicos de Andradas e Região — AGRIFAN) have, for the most part, a simplified production design, with limited diversity. Most of these organic farmers — especially the coffee growers — use organic fertilizers purchased externally to rural properties (e.g., castor oil meal and meat-and-bone meal), and they adopt the management of spontaneous weeds as the main soil coverage technique. In general, it can be seen that the soils have characteristics linked to appropriate values for soil fertility, but they have some problems related to physical and biological characteristics. Seeking to evaluate the soils of organic coffee (Coffea arabica) and grape (Vitis labrusca) cultivations, as well as the alterations in the soil when these plantations are subjected to intercropping with green manure, observation units were installed in three properties in the municipalities of Andradas and Caldas in the state of Minas Gerais. Four treatments were used: Treatment EE — Coffee or grape cultivation with weeds (control); Treatment FG — Coffee or grape cultivation with pigeon pea (Cajanus cajan); Treatment MI — Coffee or grape cultivations with millet (Pennisetum glaucum); and Treatment FM — Coffee or grape cultivation with intercropped green manures (intercropping of pigeon pea and millet). It was adopted a participatory methodology for assessing the quality of the soil. As a conclusion of this work, it is possible to affirm that: the green manure contributes to improving various indicative features of soil quality.
