Abstract

INSUASTY B, Liliana; BURBANO O, Hernán  and  MENJIVAR F, Juan C. Dinamic of the cadmium in soils cultivated with potatoes in Nariño, Colombia. Acta Agron. [online]. 2008, vol.57, n.1, pp.51-54. ISSN 0120-2812.

The mobility of cadmium and fixation in soils cropped with potatoes in Túquerres, Pasto and Guachucal Nariño, Colombia was evaluated. Samples with an auger of 11 cm diameter and 40 cm in length were taken. On these soil samples applications of 0, 50, 100 and 150 ppm cadmium were, and incubated during a 4 month period under field capacity. In this soils the content of total exchangeable cadmium do not overcome the permissible limits established by World Health Organization-Food and Agriculture Organization of the United Nations. The highest concentration of cadmium applied in the for of total Cd and changeable Cd was found in the higher third part of cores, which indicates a low mobility of the element in the soil profile.

Keywords : Solanum tuberosum; total cadmium; exchangeable cadmium.
