The Pfeiffer chromatography technique is a simple and affordable tool, the main objective was to compare the results of the qualitative evaluation of Pfeiffer chromatography and the analysis of physical, chemical and biological parameters of compost, humus and agricultural soil in Lamay. The work methodology was based on the extraction of samples of compost, humus and agricultural soil at a depth of 0 to 40 cm. Sodium hydroxide (NaOH) was used as reagents for sample preparation and for the preparation of the Whatman filter. silver nitrate (AgNO3) was used, and then subjected to chromatographic analysis, the results were compared with the Chilean Standard NCh - 2880.2004 for compost, Mexican Standard NMX-AA-180-SCFI-2018 for humus and Supreme Decree No. 005 – 2022 – MIDAGRI for agricultural land in order to analyze the quality of the samples. The statistical analysis used was ANOVA with probability of 0.05 using Tukey's test of means at 95% reliability. As results, it was obtained that the compost is of optimal quality, with the most significant zones being the internal and central zone of the chromatogram, complying with the standard for compost, the humus is of optimal quality, having the internal zone of the chromatogram as the most significant zone, complying with with the norm for humus as organic fertilizer and the agricultural soil is of poor quality, considering the internal zone of the chromatogram as the most significant zone. It is concluded that the Pfeiffer chromatography technique is useful to determine the quality of compost, humus and agricultural soil.
