The document detailed the information on the influence of humic and fulvic acids as an alternative for the management of soils affected by acidity in the corn crop, in Ecuador. The cultivation of corn is one of the main crops in the country, due to its demand and volume of production; In addition, the amount of products that are generated from this crop are used for human and animal nutrition and industrial use. Humic and fulvic acids are complex organic molecules, formed by the decomposition of organic matter, which directly influences soil fertility, influencing the absorption of nutrients and therefore adequate plant growth. The conclusions determine that humic acids solve the different effects that occur in soils such as salinization, calcification, decrease in fertility and destruction of useful microorganisms, increase in erosion and desertification, presence of diseases, accumulation of toxic residues due to the application of chemicals; The effects that humic acids cause in the soil is that if the soil is clayey, its structure and aeration are improved, thus its permeability is increased, which allows plants to improve their metabolic activities and germination power; In the roots, their absorption capacity improves, which together with the photosynthesis of the leaves increases the vigor and productivity and the low yield of the corn crop is due to the lack of application of humic acids with adequate doses during the crop cycle, which which has made it essential to apply products based on humic and fulvic acids to improve development.The document detailed the information on the influence of humic and fulvic acids as an alternative for the management of soils affected by acidity in the corn crop, in Ecuador.

El cultivo de maíz es uno de los principales cultivos del país, por su demanda y volumen de producción; además la cantidad de productos que se generan de este cultivo sirven para la alimentación humana y animal e uso industrial. Los ácidos húmicos y fúlvicos son moléculas complejas orgánicas, formadas por la descomposición de materia orgánica, lo que influye directamente a la fertilidad del suelo, incidiendo en la absorción de nutrientes y por ende un crecimiento adecuado de las plantas. Las conclusiones determinan que los ácidos húmicos solucionan de los diferentes efectos que ocurren en los suelos tales como salinización, calcificación, disminución de la fertilidad y destrucción de los microorganismos útiles, incremento de la erosión y desertificación, presencia de enfermedades, acumulación de residuos tóxicos por la aplicación de productos químicos; los efectos que causan los ácidos húmicos en el suelo es que si el terreno es arcilloso se mejora su estructura y aireación, por lo que se aumenta su permeabilidad, lo que permite que las plantas mejore sus actividades metabólicas y el poder germinativo; en las raíces mejora su capacidad de absorción lo que junto con la fotosíntesis de las hojas aumenta el vigor y productividad y el bajo rendimiento del cultivo de maíz se debe a la falta de aplicación de ácidos húmicos con dosis adecuadas durante el ciclo del cultivo, lo que ha hecho imprescindible aplicar productos a base de ácidos húmicos y fúlvicos para mejorar el desarrollo.
