AGUIRRE, Sonia E.; PIRANEQUE, Nelson V.  e  DIAZ, Carlos J.. Valuation of Soil State in Dry Tropical Forest Zone by Analytical Techniques and Chromatograms. Inf. tecnol. [online]. 2019, vol.30, n.6, pp.337-350. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642019000600337.

Three land uses were analyzed and evaluated: Forest-B, Vegetables-H, and Grass-G in a tropical dry forest area using standard analytical techniques and Pfeiffer´s circular chromatography. The chromatogram pattern evaluation was carried out by characterization and punctuation of pattern zones, followed by graphics and analytical examination in a factorial design. Then, the collected data were associated with physical and chemical soil characteristics. The results showed differences regarding use. Soil H exhibited chromatograms with less tooth formation, dark colors, and less integrality; soil B presented zones with cationic relationships that showed an induced nutrient deficiency, and soil G exhibited light colors, large teeth, and better integration of zones, with higher carbon content. The use of the evaluated techniques provides a holistic and reliable diagnosis for management and resource sustainability.

Palavras-chave : soil uses; Pfeiffer’s circular chromatography; soil quality; soil analysis; pattern evaluations.
