Abstract
The aim of the research was to relate the spectral response of rice to heavy metal concentration in soil of Albufera Natural Park. The spectral observations were values of the crop reflectance obtained from the Landsat-5 Thematic Mapper NIR and Red hands expressed by the Normalized Difference Vegetation Index, NDVI. Soil samples of the surface 20 cm were analyzed for total and extractable heavy metal content. The strongest correlations between NDVI and heavy metal in soil were found between the available fractions of Ni, Pb, Cd, Cu and Zn and the toxicity index, Zn equivalent, defined by Zn Eq = (1× Zn) + (2× Cu) + (8× Ni) where metal concentrations are in mg per kg of soil.
