Cadmium (Cd) is a toxic heavy metal wich is harmful to humans. Its bioaccumulation capacity, as well as the constant entry of cadmium into the system, increases its concentration in soils. Cocoa almonds (Theobroma cacao L.) accumulate this metal, therefore, the objective of this research was to evaluate the effect of biodegradable products applied to the soil on the accumulation of cadmium in the cocoa pod and the impact on productivity of almonds. Two dosages of the following products were tested: Avibiol (120 L.ha−1 and 240 L.ha−1 ), Monty´s liquid carbon (8 L.ha−1 and 16 L.ha −1 ) and Avical (without Avical and 20 L.ha−1 ), having as constants a dosages of Codahumus 20 (8 L.ha−1 ) and E-codargón (20 L.ha−1 ) in all treatments, additionally a control without the application of any product, generating thus, eight treatments plus the control were arranged in a Randomized Complete Block Design. The results indicate a significant increase in the active rootlets dry weight due to the effect of all the products at the highest dosage (obtaining 215.8 g. m−3with treatment 8 in comparison with the control which reached 120.0 g. m−3 ). The productivity was also favored with the application of the products, showing significant differences in the harvest of almonds with the application of all the products at the highest dosage (obtaining 1112.83 kg.ha−1 with treatment 8 in contrast to the control with 814 kg.ha−1 ). Regarding the cadmium extraction, no significant differences were found. Nonetheless, a decreasing tendency of cadmium concentration in cocoa is shown with application of the tested products.
