| description |
The presence of heavy metals in cocoas crop is becoming a problem for farmers and cooperatives at Huánuco and Ucayali regions, Peru. In this research cadmium and lead contents in cocoa soils and leaves were evaluated. For it, soil and foliar samples were collected in 22 organic crop plots located at Huánuco (17) and Ucayali (5) regions. Pearson correlation analysis was performed between available content of lead and cadmium in soils with foliar variables (P, Mg, Ca, Zn, Cd, Pb) and soil (Sand, Clay and K) variables. 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 available cadmium and lead in soils were 0.53 ppm and 3.02 ppm and in leaves were 0.21 ppm and 0.58 ppm respectively. |

En el presente trabajo se evaluaron los contenidos de cadmio y plomo en suelos y hojas del cacao en estas regiones. Para el efecto se recolectaron y analizaron en laboratorio muestras tomadas en 22 parcelas con cultivos orgánicos de esta especie, 17 en la región Huánuco y cinco en la región Ucayali. Se realizaron análisis de correlación de Pearson entre los contenidos de plomo y cadmio disponibles en el suelo con variables foliares (P, Mg, Ca, Zn, Cd, Pb) y del suelo (arena, arcilla y K). En los suelos, sólo en el caso de potasio se presentan deficiencias; mientras que en el tejido foliar se presentaron deficiencias de N, P, K, Mg y Zn. Los valores promedio de cadmio y plomo disponible en los suelos fueron 0.53 y 3.02 ppm y en las hojas de cacao de 0.21 y 0.58 ppm respectivamente.application/mswordspaUniversidad Nacional de Colombia Sede Palmirahttp://revistas.unal.edu.co/index.php/acta_agronomica/article/view/38134Universidad Nacional de Colombia Revistas electrónicas UN Acta AgronómicaActa AgronómicaHuamanI-Yupanqui, Hugo Alfredo and Huauya-Rojas, Miguel Ángel and Mansilla-Minaya, Luis Germán and Florida-Rofner, Nelino and Neira-Trujillo, Gilmer Milton (2012) Presence of heavy metals in organic cacao (theobroma cacao l.) crop.
