Conventional systems are characterized by the use of agrochemicals, intensive tillage, monocultures and other practices that can affect the ecosystem. On the other hand, agroecological systems are characterized by the contribution of organic matter, agrobiodiversity, nutrient recycling and other activities that ensure the sustainability of the environment, human health and the peasant economy. The state of the soil is unknown of these systems studied, so the objective of this study was to qualitatively evaluate the state of the soil using Pfeiffer chromatography. In order to characterize the management and use of the soil of the productive systems, surveys were carried out with farmers. In addition, soil samples were obtained in plots of the two production systems for chromatographic analysis. The chromatograms were interpreted, evidencing that the studied systems have their own characteristics according to soil management. The chromatograms of the agroecological systems showed a healthy and balanced soil, due to the shapes, colors and harmony that the different zones appeared. On the contrary, the chromatograms of the conventional systems revealed darker colors and little integration between their zones, which evidenced lower organic matter content and biological activity. Pfeiffer chromatography demonstrated the difference in the state of the soil in these two productive systems, evidencing the importance of good soil management to preserve its state and balance within ecosystem services. Key words: soils, chromatograms, conventional production, agroecological production. |
