THE USE OF PFEIFFER CHROMATOGRAPHY AS A TOOL FOR EVALUATING AGROECOLOGICAL MANAGEMENT IN AN AGRICULTURAL PROPERTY IN THE MUNICIPALLY OF BOQUEIRÃO – PB

Pfeiffer Circular Chromatography is seen as a tool used for physical separation of complex mixtures with the potential to holistically portray the biological attributes of the soil, providing the monitoring of agroecological managements. The objective here was to evaluate the soil quality of a family-based agroecosystem in the municipality of Boqueirão - PB, in order to guide decision-making with regard to the managements used. The design of the research is in accordance with (Pfeiffer, 1980), and has been adapted to the conduction optics for the peasantry. Soil samples were collected at a depth of 0-20cm, with Dutch auger dried in the shade and screened. Two solutions were used in different stages of conduction: dispersant (NaOH) and photoreactive (AgNO3). JPLAB 15cm filter papers were used, which were prepared for the production of chromatograms. The samples went through a stirring process interspersed with a rest period: 15min, 1h and 6h. The results showed good revelations of the chroma, which allowed us to infer the main indicators of each area. From the interpretations that chromatography allows, it was found that chroma C presents the best results in terms of soil health, since it expressed high enzymatic activity. On the other hand, chroma A and B did not express good conditions, evidencing the need for changes in the management condition.
