“…Radial lines, which extend from the middle of the chroma and reach the EZ, correlate with the formative forces of the soil (Maseda, 2016). These forces indicate the soil's ability to provide conditions necessary for the biological development and dynamic equilibrium of the chemical and physical fractions of the system.…”

“…Although PC has already been evaluated, under experimental conditions, as an indicator used to determine mineral, organic and protein components for soil analysis (Pfeiffer, 1984;Kokornaczyk et al, 2016;Maseda, 2016), this chromatography method is unknown to farmers and specialists and it is not disseminated at universities. PC still demands specific studies on the different conditions for each system of agricultural production.…”

Soil monitoring is fundamental to promote sustainability agroecosystems. It is necessary to consider indicators that bring together biological, physical, chemical and inter-relational attributes. Pfeiffer chromatography (PC) represents an important method for soil diagnosis, so the present study aims to analyze it in order to contribute to its validation. The soil samples of 12 production systems were evaluated in quintuplicate. The chromas were elaborated using Whatman no 4 filter paper, and the soil extract was performed by sodium hydroxide solution 1%. The results were obtained using revealing solution (AgNO3 0.5%) ascension by capillarity, and the chrome zones: central, internal, medium and external were correlated to soil penetration, chemical, biological and enzymatic parameters, respectively. Variance analysis was applied to the results that presented normal distribution and the means were compared by Scott-Knott test. T-test for Spearman correlations and principal component analysis were used to evaluate the correlations. There was negative correlation between the central zone and the average penetration resistance within the range 0-40 cm in depth. The internal, medium and external zones presented positive correlation with organic matter, carbon microbial biomass, and enzymatic activities, respectively. Quality standard features such as coloration, size and proportion of zones, presence of enzymatic clouds, peaks and radial lines were also confirmed. Thus, the standardization developed by this study contributed to validation of PC. Since PC is a low-cost and easy-to-perform method, it proves to be a useful tool allowing farmers autonomy to monitoring different agricultural systems, contributing to their production sustainable.

“…O solo é um recurso praticamente não renovável, em que está vulnerável a uma rápida degradação se mal manejado, taxas baixas de formação e regeneração extremamente lenta, formando pequenas porções ao longo de anos (MASEDA, 2016). Deste modo, a perda de matéria orgânica em áreas manejadas com fins agrícolas, representa o principal impacto na queda dos níveis de fertilidade do solo, e por consequência, reduz os seus estoques de nutrientes, o que remete as alternativas de manejo alternativo com base em um modelo agroecológico (PINHEIRO, 2015).…”

O manejo racional dos solos e seu diagnóstico são cruciais e devem ser considerados quando se planeja uma produção agrícola sustentável. Portanto, o objetivo com esta pesquisa foi avaliar a evolução da qualidade do solo através da Cromatografia de Pfeiffer após o uso de práticas agroecológicas em um sistema experimental. O trabalho foi realizado no município de Bananeiras, Paraíba, em um subsistema experimental com plantio de Noni (Morinda citrifolia), localizado na primeira chã do Centro de Ciências Humanas Sociais e Agrárias da Universidade Federal da Paraíba. Foram coletadas em campo três amostras de solo na camada 0-20 cm e levadas ao laboratório de Agroecologia para realização da prática da Cromatografia de Pfeiffer. Foi utilizado o processo de interpretação do cromatograma, verificadas no decorrer de utilização de práticas agroecológicas como aplicação de biofertilizante, adubação verde e monitoramento do solo no subsistema. Como resultados, os cromatogramas antes das práticas agroecológicas obtiveram suficiente saúde do solo, já para os cromatogramas dos solos após as práticas agroecológicas houve melhoria para as todas as zonas da cromatografia. Portanto, as práticas agroecológicas proporcionaram melhorias na qualidade e vida do solo e a cromatografia de Pfeiffer foi fundamental para diagnosticar a saúde do solo.
