The present work, carried out with a group of small farmers of the community of Camurituba- Beira, in the municipality of Abaetetuba - PA, aims to verify the economic viability of the production of organic fertilizer in quantity and quality adequate to increase and diversify the agricultural production, aiming local economic development. As a methodological procedure, interviews were, initially, made with the farmers participating in the project, to determine the characteristics of the productive areas and the main difficulties faced to ensure economic survival. In the second stage three theoretical and practical workshops were carried out to produce three types of fertilizer with different organic residues that are tested in the different crops, to verify the quality and quantity of fertilizer needed to increase their productivity. After tests of the different types of fertilizer, a cost-benefit balance is carried out and an agroecological data sheet is constructed in order to show step-by-step the procedures and techniques of organic fertilizer production to encourage small farmers to adopt these techniques to increase the productivity of their crops. At the farmers' request, a last workshop, on the possibilities of using not only organic fertilizer but also natural pesticides to verify the possibility of gradually migrating to agricultural production that can be considered organic has been realized. The workshop was of interest to several farmers who expressed their intention to try step by step to produce organic products and to test the economic viability.

Estudo da contaminação por hidrocarbonetos em postos de serviços de Abaetetuba-PA utilizando georadar
(Universidade Federal do Pará, 2007) ALMEIDA, Fabíola Magalhães de; LUIZ, José Gouvêa; http://lattes.cnpq.br/8676530374310847
The work presents the results of a geophysical survey using the Ground Penetrating Radar (GPR) method to detect possible zones of contamination caused by derivatives of hydrocarbons in service stations of the urban region of the city of Abaetetuba, in the state of Pará. The methodology was applied in service stations because they are the main potential source of soil and ground water contamination by fuel in the cities. Basic concepts about oil and contamination and its interaction with the ground are presented, together with the basic principles that allow the understanding of the GPR method as applied to the addressed problem. During the work, the depth to the water table was measured to construct an underground flow map. The geophysical interpretation was assisted by the knowledge of the local underground water flow that gives indication on the direction of contamination movement. The correlation of the GPR data with the underground flow and the information about the stations history allowed to classify them as suspected of producing contamination and possibly contaminated.

Metodologia geofísica aplicada à pesquisa de salvamento arqueológico nos sítios Bittencourt, Jambuaçu e Jaburu, Estado do Pará
(Universidade Federal do Pará, 2006-05-02) ARAGÃO, Rigler da Costa; LUIZ, José Gouvêa; http://lattes.cnpq.br/8676530374310847
We present the results obtained in the application of geophysical methods to help the archaeological rescue of remains in the three following sites in Pará, northern of Brazil: Bittencourt, located in Abaetetuba; Jambuaçu, located in Moju; and Jaburu, located in Almeirim. Magnetometry, scintillometry and ground penetrating radar (GPR) were used in the study. Magnetic measurements were taken as the main tool to indicate places for excavation. GPR was used to confirm the anomalies detected with the magnetic method and provided a restriction to the magnetic anomalies caused by non-archaeological artifacts. Scintillometry was used as an attempt to map the archaeological black earth (ABE) or Terra Preta Arqueológica (TPA) soil through the detection of natural gamma ray emitted by the ground. The excavations carried out on the indications of magnetometry and GPR yielded the recovery of ceramics, faience, lithics, and iron artifacts. The scintillometric data showed that exist a good correlation between low radiation and large thickness of ABE (TPA). The used geophysical methodology proved to be efficient and quick with no destructive impact to the sites.
