MEDINA SAAVEDRA, Tarsicio; ARROYO FIGUEROA, Gabriela  y  PENA CABALLERO, Vicente. Chromatography of Pfaiffer in the analysis of soils of productive systems. Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.3, pp.665-673. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v9i3.1223.

The Pfaiffer chromatography is a qualitative analysis technique that can be used in soils, composts and biofertilizers, being able to quickly observe the relationship between microorganisms, organic matter and minerals, as elements that compose them. For the agricultural producer, it is important to know the conditions of the soil or supplies that he uses to obtain better results in his crops. The objective of the work was to perform Pfaiffer chromatography to analyze the soils of productive systems and compare some qualitative characteristics. The soil samples were taken at random from different plots, the first one with conventional agronomic management, the next one from a land with temporary production and the last one from an organic production system, were analyzed by Pfaiffer chromatography separately. The chromatograms were interpreted, being able to observe that the three types of soil provide the characteristics of the farming system to which they belong.

Palabras llave : chromatograms; conventional; organic; temporal.
