Caracterización de suelos mediante la técnica de cromatografía en papel en el Área de Influencia del Sistema de Agua de Riego Canal Central Toacaso, Cantón Latacunga, Provincia de Cotopaxi.

The current research was made in the influence area from Toacaso Central Canal Irrigation System, it had as aim to characterize the soil, through the paper chromatography technique. For fulfilling the aim, it is taken into account three of six branches, being Cuicuno, El Pueblo and La Calera, and it was used the proposed methodology by Restrepo-Rivera & Pinheiro (2011), which was collected ten soil samples for each branch, and was performed the chromatographic analysis. The same way, it was performed the surveys same number to the producers, for knowing the technical and cultural management their agricultural production. To determine the soil nutritional status was collected composite samples from each the branches, what were sent to the National Institute for Agricultural Research (INIAP) laboratory for analysis. With the surveys got data, plus the analyzed chromatograms, it can say, what in the Ramal Cuicuno soil, it is made few aeration tasks, it presents agricultural machinery good management, there is microbiological activity and a organic matter low amount, in the area. It is grown pastures with the agrochemicals use, such as glyphosate, nitrates and sulfates, this shows, which there is organic matter mummification and the degradation possibility. Within Ramal El Pueblo soil, it was aeration works, it is evident the agricultural machinery excessive use, affecting the soil structure, a organic matter medium level, the agricultural products use and with the compaction beginning. The Ramal La Calera soil shows a machinery inadequate handling, they make aeration tasks, there is organic matter presence at a medium level, they use agrochemicals moderately, and use soil amendments into some cases. The branches production systems types under study are considered temporary and conclude, what the influence area from Toacaso Central Canal Irrigation System is managed temporarily, with conventional agricultural practices with the organic soil amendments application. The chromatography technique allows to determine the soil health, allowing to make decisions for applying educated amendments; to avoid soil contamination, by the agricultural products use.
