This document dealt with aluminum toxicity, as a limiting microelement for agricultural production. Aluminum toxicity can cause growth alterations in plants, effects on membrane permeability and nutritional and vacuolar content alterations, therefore it can cause certain metabolic and physiological variations produced in root cells as the primary site of action. of metal, thus obtaining a general and coherent idea of what is proposed as the functioning of certain tolerance mechanisms in these varieties and an explanation of some of the effects produced by aluminum. Due to the details, it was determined that the studies related to aluminum toxicity are focused especially on crops such as rice, corn, wheat and vegetables; It is possible to achieve the reduction of the toxic effects of Al3 + and to maintain a balanced nutrition of the cultivated plants, by applying lime to the soil; Al3 + toxicity is the most limiting factor for plant growth and development in acid soils, especially if the pH is ˂ 5.0; root elongation establishes a clear definition regarding the tolerance of the different varieties to metal; the different concentrations of aluminum affect the elongation of the root; the root aluminum concentration is clearly higher than that found in the aerial part of the plant and the levels of aluminum in the soil had an effect on production.This document dealt with aluminum toxicity, as a limiting microelement for agricultural production.

La toxicidad por aluminio, puede causar en las plantas alteraciones en el crecimiento, efectos sobre la permeabilidad de la membrana y alteraciones nutricionales y de contenido vacuolar, por tanto pueden provocar ciertas variaciones metabólicas y fisiológicas producidas en las células radiculares como sitio primario de la acción del metal, obteniendo así, una idea general y coherente de lo que se propone como funcionamientos de ciertos mecanismos de tolerancia en estas variedades y una explicación a algunos de los efectos producidos por el aluminio. Por lo detallado se determinó que los estudios relacionados con la toxicidad de aluminio están centrados especialmente en cultivos como arroz, maíz, trigo y hortalizas; es posible lograr la reducción de los efectos tóxicos del Al3+ y mantener una nutrición equilibrada de las plantas cultivadas, mediante la aplicación de cal al suelo; la toxicidad por Al3+ es el factor más limitante del crecimiento y desarrollo de las plantas en suelos ácidos, sobre todo si el pH es ˂ 5,0; la elongación radicular establece una definición clara en cuanto a la tolerancia de las diferentes variedades al metal; las diferentes concentraciones de aluminio afectan la elongación de la raíz; la concentración de aluminio radicular es claramente superior a la encontrada en la parte aérea de la planta y los niveles de aluminio del suelo tuvieron efecto sobre la producción.
