Abstract

The current model of agricultural production in Brazil, propelled during the 1970's through the Green Revolution, brought and deepened some of the problems in the countryside, be they social and/or environmental. In the context of the struggle for land, the peasant lean towards exclusion in the productive process, in detriment of the agribusiness. As for the environmental matters, we highlight soil and water contamination through agrochemicals, accelerated erosion, exacerbated use of genetically modified organisms (GMO), among other issues. On this context, life in/of soil might be compromised, as well as agricultural production and the maintenance of the peasant. The goal of this research is to analyze and quantify the soil macrofauna, as an indicative of soil quality. The work will be spread across four areas, under different uses on the rural camp of the Landless Rural Workers Movement (Movimento dos Trabalhadores Sem-Terra) "Companheiro Keno" in the city of Jacarezinho/PR: pasture, wood, conventionally prepared garden and also under agroecological handling. The adopted methodology will be according to EMBRAPA Agrobiology (2001), with a few modifications. The soil macrofauna will be quantified and qualified on different depths, from 0-10cm, 10-20cm and 20-30cm. Furthermore, routinely chemical analysis will be conducted: soil pH, organic carbon, N, Cation exchange capacity (CEC), Percent base saturation (BS), H + Al.
