dc.descriptionFertilization problems in Ecuador are increasing over time, it is common to observe effects such as: loss of productive capacity, erosion and salinity in production areas. This is caused by improper use of fertilizers, or poorly designed fertilization programs specific to the corn crop. The absorption curves are a viable alternative for the correct use of fertilization programs, since they are coupled to the different agroecological conditions where it is grown. The study carried out determined that in each area a different level curve was presented for each element evaluated. This leads farmers to apply these curves by means of their agronomist consultant, to minimize nutrient losses and to increase the efficiency of these. It is known that the absorption curve is an approximate value to the real value that the corn plant uses to achieve adequate development and production. The area with the highest productive level due to the application of this equation is Babahoyo, followed by Ventana and Puebloviejo. At a general level, the results show the formation of linear curves, that is, of expression y = ax + b, for elements such as nitrogen, phosphorus and potassium. However, in elements such as magnesium and even sulfur, polynomial expression curves y = ax2 + b were determined. The use of the absorption curve guarantees an efficient use of fertilizers, avoiding losses and improving the quality of the corn production system in the evaluated areas.es_ES

dc.description.abstractLos problemas de fertilización en el Ecuador están aumentando con el pasar del tiempo, es común observar en las zonas de producción efectos como: la pérdida de capacidad productiva, erosión química y salinidad. Esto se produce por un uso inadecuado de los fertilizantes, o programas mal diseñado de fertilización específicos para el cultivo de maíz. Las curvas de absorción son una alternativa viable para el uso correcto de programas de fertilización, ya que estas se acoplan a las diferentes condiciones agroecológicas donde se cultiva. El estudio realizado determinó que en cada zona se presentó, una curva de nivel diferente para cada elemento evaluado. Esto conlleva a que los agricultores al aplicar estas curvas por medios de su agente asesor agrónomo, minimicen las pérdidas de nutrientes ya aumenten la eficacia de estos. Se conoce que la curva de absorción, es un valor aproximado al valor real que utiliza la planta de maíz para lograr un desarrollo y producción adecuada. La zona con mayor nivel productivo por la aplicación de esta ecuación es Babahoyo, seguida por Ventana y Puebloviejo. A nivel general los resultados muestran la formación de curvas lineales, es decir de expresión y=ax+b, para elementos como nitrógeno, fósforo y potasio. Sin embargo, en elementos como magnesio e incluso azufre se determinó curvas polinómicas de expresión y=ax2+b. El empleo de la curva de absorción garantiza un uso eficiente de fertilizantes, evitando perdidas y mejorando la calidad del sistema productivo maicero, en las zonas evaluadas. Pes_ES
