MÉTODOS DE INTERPRETAÇÃO PARA TESTE DE QUALIDADE EM SOLOS A PARTIR DA CROMATOGRAFIA CIRCULAR PLANA (FCC)

Abstract

Flat circular chromatography (FCC) is a method of separating components that is divided into two phases, stationary phase and mobile phase. The stationary phase involves the reaction of 1% Sodium Hydroxide (NaOH) with soil sample and Silver Nitrate impregnation (AgNO3) in the filter paper. The mobile phase involves absorbing the filter paper from the Sodium Hydroxide solution with soil. Currently the Plana Circular Chromatography (FCC) indicates a reading of the life quality of the soil through the harmony of colors and drawings between mineral, organic, energetic and electromagnetic components. This inter-relationship consists of the metabolism of the living soil as well as the availability and efficiency, being the solubility, concentration, constancy and biological quality of the nutrients. In Brazil, the analysis method has been widely disseminated in the agricultural sciences. However, the challenge in interpreting the broad spectrum of chromatogram results was based on the writing of this article whose goal was to accomplisha systematization of the main methodologies of analysis of results and interpretations of the zones formed by chromatograms as well as of innovative searches outside and within Brazil. The results present research with the characterization of types of management and productive arrangements of various soils. Also, with the use of software analyze image properties, distribution and particle numbers for determining tonality degrees, saturation and color entropy. And through experimental statistics the correlation of these chromatographic patterns and mineral and organic content of chemical soil analysis results. It is concluded that the advancement in methodologies of understanding of the FCC's results showed significant growth in the last decade, with the use of high-precision scientific and technological methods, opening the possibility of consolidating the FCC method as a real instrument for soil health analysis as well as compounds. This article presents itself as a reading for the practice of new methodologies that lead to greater understanding of chromatograms.
