Item Open Access Evaluación de la efectividad de sedimentos de la Laguna Colta, como abono orgánico, en el cultivo de cilantro (Coriandrum sativum L.) en la granja experimental de la PUCE-SI Ibarra-Imbabura(Pontificia Universidad Católica del Ecuador Sede Ibarra, 2020-02) Tituaña Yamberla, Edwin AlexanderThe existence of the deterioration of the soils and the decrease of their useful life, is a reality that is lived in Ecuador Where the main cause of the problem is the agronomic technical ignorance of the crops, mainly due to the inappropriate use of chemical fertilizers, which deteriorate the characteristics of the soil. An alternative to this problem is the use of organic fertilizers that improve soil texture and, in turn, reduce environmental pollution. The sediments of the dredging of lagoons, are a potential alternative of recovery of soils that is required to explore. The main objective of this study was to evaluate the behavior of dredged sediments of the Colta Lagoon as an alternative organic fertilizer for coriander in the Ibarra Canton, province of Imbabura. The experimental site was the Experimental Farm of the Pontifical Catholic University of Ecuador, Ibarra Headquarters. The investigation consisted of applying four different doses of the sediments extracted from the Colta Lagoon, same that were processed as fertilizer by drying, oxygenated, composted, inoculated with selected bacteria; and finally sifted, Subsequently, this sediments they were incorporated into the soil by mixing, graduating the application of the fertilizer based on a volume of 0.6 m3 of soil corresponding to an area of 3 m2, obtaining the treatments T1 (82.14 kg of fertilizer without soil), T2 (61.61 kg of fertilizer with 20.53 kg of soil), T3 (41.07 kg of fertilizer with 41.07 kg of soil), T4 (20.53 kg of fertilizer with 61.61 kg of soil), T5 (82.14 kg of soil without fertilizer). The benefits of the practice were evidenced through the performance data, as well as with the results of physical-chemical analysis of the soil before and after the application of the fertilizer. Achieved whit the best T3 treatment a production of 31 388 kg ha-1 and on the other hand obtaining a safe soil. The scope of the data shows that the strategy used through the use of sediments in agriculture is an effective alternative to recover degraded soils; thus, promoting the practice of environmentally sustainable agriculture.
