| dc.description | In Los Ríos, agriculture is the predominant economic activity and has experienced a notable evolution in terms of crops, varieties, methods, and tools used over time. A significant impact on the environment in which it is present and plays a crucial role in the social and economic activities of the people residing in that region, exerting various levels of pressure on the soil and causing its deterioration. In this sense, the research sought to: identify the chemical properties of the eroded soils in the CEDEGE Babahoyo area. For this purpose, samples were taken in 30 agricultural properties within the CEDEGE-Babahoyo Project area, as a primary requirement the planting of short-cycle crops. Continuous quantitative variables and inferential statistics (t test, mean, probability) were used. The systematic-stratified sampling method was used to select the farms. The variables studied were Hydrogen Potential, Cationic Exchange Capacity, Electrical Conductivity, Macroelements and Microelements. Data collection will be carried out once the samples have gone through the drying process using the oven and air-drying method. The pH levels in the sampled sectors present ranges that are between moderately acidic and practically neutral, in the case of the CEC ranges they are within what are considered medium levels. The EC ranges show values with problems in all the areas evaluated. The levels of macroelements such as nitrogen, phosphorus, and sulfur, as well as potassium, are adequate for the soils of the sector; however, calcium and magnesium levels may be considered inadequate. The values of the microelements zinc and boron are within the average; however, the levels of iron, copper and manganese can be considered toxic to crops. | es_ES |

| dc.description.abstract | En Los Ríos, la agricultura es la actividad económica predominante y ha experimentado una notable evolución en términos de cultivos, variedades, métodos y herramientas utilizadas a lo largo del tiempo. Un impacto significativo en el entorno en el que está presente y desempeña un papel crucial en las actividades sociales y económicas de las personas que residen en esa región, ejerciendo diversos niveles de presión sobre el suelo y provocando su deterioro. En este sentido la investigación busco: identificar la propiedades química de los suelos erosionados en la zona de CEDEGE Babahoyo. Para el efecto se tomaron muestras en 30 predios agrícolas dentro de la zona del Proyecto CEDEGE-Babahoyo, como requisito primordial la siembra de cultivos de ciclo corto. Se utilizaron variables cuantitativas continuas y estadística inferencial (prueba de t, media, probabilidad). Para la selección de las fincas se empleó el método de muestreo sistemático-estratificado. Las variables estudiadas fueron: Potencial Hidrogeno, Capacidad de intercambio catiónico, Conductividad Eléctrica, Macroelementos y Microelementos. La colecta de datos se realizará una vez que las muestras hayan pasado por su proceso de desecación mediante el método de estufa y secado al aire. Los niveles de pH en los sectores muestreados presentan rangos que se sitúan entre moderadamente ácidos y prácticamente neutro, en el caso de los rangos de CIC se encuentran dentro de los considerados niveles medios. Los rangos de CE muestran valores con problemas en todas las zonas evaluadas. Los niveles de los macroelementos como nitrógeno, fosforo y azufre, así como potasio, son adecuados para los suelos del sector; sin embargo, los niveles de calcio y magnesio pueden considerarse no adecuados. Los valores de los microelementos zinc y boro están dentro del promedio; sin embargo, los niveles de hierros, cobre y manganeso pueden considerarse tóxicos para los cultivos. | es_ES |
