| description | In the most acid soils worldwide, covering up to 40% of the surface potentially usable for crops, aluminum is the most growth and yield limiting factor. It is estimated that about 85% of the total land surface in Colombia is composed by acid soils where the productivity of most food crops is severely restricted due to soil acidity and aluminum toxicity. In acid mineral soils with pH values below 5,5 a large proportion of the cation exchange sites of clay minerals is occupied by aluminum where it specially replaces other polyvalent cations as Mg2+ and Ca2+ and simultaneously acts as a strong absorber of phosphate. The strong competing effect of aluminum on calcium and magnesium uptake explains why the molar ratios of Ca/Al, Mg/Al or (Ca+Mg+K)/Al in the soil or nutrient solutions are sometimes better parameters for predicting of the risk of aluminum-induced bases deficiency than the concentrations of any individual elements. The initial effect of aluminum stress is the inhibition of root growth, moreover aluminum accumulation is an indicator of Al-sensitivity takes place in the root apex; Al-resistance mechanisms are confined mainly to the root apex; and callose formation is induced in apical cells of the roots. Some amelioration possibilities to aluminum stress are: application of organic matter to the soil, root colonization with mycorrhizas, application of organic acids to the nutrient solution, foliar application of phosphorus, and lime application to the soil, Al-tolerant plants selection, and transgenic tolerant plants. |

El aluminio es el factor más limitante del crecimiento y productividad en los suelos ácidos del mundo, que abarcan más de 40% de la superficie agrícola. Alrededor de 85% del territorio colombiano está compuesto por suelos ácidos, en los cuales la productividad de plantas se restringe debido a la acidez del suelo y la toxicidad por aluminio. En suelos minerales ácidos con pH inferior a 5,5 gran proporción de los sitios de intercambio de las arcillas está ocupado por aluminio, en donde este reemplaza otros cationes como el Mg2+ y el Ca2+ y simultáneamente se adsorbe a los fosfatos. El efecto de competencia del aluminio sobre la toma de calcio y magnesio justifica que las relaciones Ca/Al, Mg/Al o (Ca+Mg+K)/Al en el suelo o en las soluciones nutritivas son mejores parámetros para predecir el riesgo de deficiencia de bases inducidas por aluminio, que la concentración de alguno de los elementos en forma individual. El efecto inicial del estrés por aluminio es la inhibición del crecimiento radicular, además, la acumulación de aluminio indica que la sensibilidad al elemento ocurre en el ápice radicular; los mecanismos de resistencia a aluminio están confinados principalmente en el ápice de la raíz; la producción de calosa es inducida en células apicales radiculares. Algunas posibilidades de corrección del estrés por aluminio son: la aplicación de materia orgánica, la colonización con micorrizas, la aplicación de ácidos orgánicos, la aplicación foliar de fósforo, el encalado, la selección de plantas tolerantes y la producción de plantas transgénicas tolerantes.
