Resumen

Remediation is the set of operations carried out to reduce the level of contaminants in the soil and/or subsoil. The objective of the study was to bioremediate contaminated agricultural soils using activated carbon from Cocos nucifera and mountain microorganisms to improve physicochemical parameters and reduce cadmium in Peruvian Amazon soils. For the methodology, a total area of 2000 m2 was used. Four monitoring points with 30 cm deep pits were used and 1 kg of soil was extracted from each sampling point. For the physicochemical analysis, activated carbon and mountain microorganisms were prepared. The treatments were arranged in a completely randomized design with a total of 7 treatments and 3 repetitions each: T1: soil without treatment or control group (GC); T2: activated carbon (AC) 100g; T3: activated carbon (AC) 200g; T4: activated carbon (AC) 300g; T5: mountain microorganisms (MM) 100 mL; T6: mountain microorganisms (MM) 200 mL; T7: mountain microorganisms (MM) 300 mL. The results show that T1 and T4 improve the physicochemical properties of the soil and absorb cadmium, while mountain microorganisms are only evident in T7.
