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

This research was carried out in the area of influence in Toacaso Central Canal Irrigation Water System; its objective was to characterize the soil using the paper chromatography technique. In order to meet the proposed objective, three branches Cruz 1, Yugsiche Bajo, and Cruz 2, were taken into account, and the methodology proposed by (Restrepo-Rivera & Pinheiro, 2011) was used where ten soil samples were collected for each branch and the chromatographic analysis. The exact number of surveys to the producer to know the technical and cultural management of agricultural production. To determine the compositional state of the soil, samples composed of each of the branches were collected and analyzed at the National Institute for Agricultural Research (INIAP). With the data obtained and chromatograms analyzed, it was established that the soil of the Ramal (Cross 1) presents good handling of agricultural machinery and a good amount of organic matter and microbiological activity. Where agrochemicals glyphosate, nitrates, and sulfates are used, the result of pastures in the sector, which shows a soil managed with a temporary production system, with the possibility of compaction degradation. In the soil of the Ramal (Yugsiche Bajo), there is evidence that the excess agricultural machinery affects the soil's structure and shows degradation and compaction. The presence of organic matter and the presence of high phosphorus levels are evidenced, which is the effect of the use of Poultry manure in the sector; this corroborates the soil analysis where there is a high content of High phosphorus with 53 ppm. Therefore, soil with a temporary production system already compaction and possible mummification of organic matter. The soil of the Ramal (Cross 2) shows a technician handling of machinery, with good structure, a good presence of organic matter with characteristics of poor application and decomposition. As well as shows mummification of organic matter, the agrochemicals used are glyphosates and sulfates, here we have a temporary production system, where it shows that the soil amendments are not being used correctly. From the contrast carried out, it was shown that there is a 57.14% validation of information between the soil chromatographies, surveys carried out to the producer, and the soil composition analyzes, which allows concluding that the area of influence of the Toacaso Central Canal Irrigation Water System has a temporary production system, with the beginning of degradation, saturation, and mummification of organic matter.
