| dc.description | To develop this document, the importance of Cadmium as a heavy metal was detailed: problems and effects on soil and plants. Heavy metals are generally present in the soil and in plants in low concentrations, which causes degradation in soils and contamination of them and plants. According to the above, it was determined that soil contamination with heavy metals causes environmental and public health probl ems, therefore it is necessary to carry out soil evaluations and analyzes to determine their chemical composition and make the necessary corrections. ; Cadmium is one of the heavy metals, considered the most toxic element and it is found distributed in nature and associated with other minerals; Cadmium fixation is higher in soils with high content of organic matter, with a finer texture and cation exchange capacity, which even in acid soils this metal is easily exchanged and made available to plants and it is necessary to identify the fertilizers suitable so that the accumulation of the level of Cadmium in the soil can be controlled and avoided | |

| dc.description | Para desarrollar el presente documento se detalló la importancia del Cadmio como metal pesado: problemas y efectos en el suelo y las plantas. Generalmente los metales pesados están presentes en el suelo y en plantas en bajas concentraciones, que causa degradación en los suelos y contaminación de los mismos y de las plantas. De acuerdo a lo expuesto anteriormente, se determinó que la contaminación del suelo con metales pesados causa problemas ambientales y de salud pública, por tanto es necesario realizar evaluaciones y análisis de suelo para determinar la composición química de los mismos y realizar las correcciones que sean necesarias; el cadmio es uno de los metales pesados, considerados como el elemento más toxico y que se encuentra distribuido en la naturaleza y asociado con otros minerales; la fijación de Cadmio es mayor en suelos con altos contenidos de materia orgánica, con textura más fina y más capacidad de intercambio catiónico, lo que incluso en suelos ácidos este metal se intercambia fácilmente y se hace disponible para las plantas y es necesario identificar los fertilizantes adecuados para que se pueda controlar y evitar la acumulación del nivel de Cadmio en el suelo. | |
