Abstract
The presence of heavy metals in cocoa's crop is becoming a difficulty for farmers and cooperatives at Huanuco and Ucayali regions, Peru. In this research cadmium and lead content in cocoa's soils and leaves was evaluated. For it, soil and foliar samples were collected in 22 organic crop plots located at Huánuco (17) and Ucayali (5) region. Pearson's correlation analysis was realized between content of lead and cadmium available in soils with foliar variables (P, Mg, Ca, Zn, Cd, Pb) and soil (Sand, Clay and K). According to the soil analysis only the potassium was deficient; while in leaf tissue deficiencies of N, P, K, Mg and Zn were observed. The average values of cadmium and lead available in soils were 0.53 ppm and 3.02 ppm and in foliar were 0.21 ppm and 0.58 ppm respectively.
