What is the potential impact on carbon storage of the native and introduced tree species commonly associated with coffee in the central Peruvian Amazon? Coffee is a pivotal crop within the Peruvian economy. Nevertheless, the establishment of new plantations—driven by the subsistence needs of smallholder farmers—has led to expansion into forested areas. Given the significance of this crop and the demonstrated ecosystem benefits of agroforestry systems (AFSs), the aim of this study was to evaluate the influence of native and introduced shade tree species on carbon storage in coffee plantations. This study was observational and exhibited characteristics of an unbalanced incomplete block design. Agroforestry systems (AFSs) with shade tree species such as Inga, Retrophyllum rospigliosii, Eucalyptus and Pinus, and three unshaded coffee plantations, were included in this study. The total carbon stored in each AFS was higher than in unshaded coffee plantations. Soil contributed between 47% and 91% to total carbon storage, shade trees (24–46%), coffee (2–7%), leaf litter (0.6–1.9%) and shrubs and herbaceous plants (0.02–0.3%). The AFS with R. rospigliosii achieved the highest carbon storage with 190.38 Mg ha−1, highlighting the compatibility of this species with coffee plantations, as well as its positive effect on climate change mitigation in deforested areas.
Manual técnico: Interpretación de análisis de suelos, cálculos de encalado y fertilización para los cultivos de café y cacao

El INIA, a través de la Dirección de Supervisión y Monitoreo en las Estaciones Experimentales (DSME), viene ejecutando el proyecto de inversión “Mejoramiento de los servicios de investigación y transferencia tecnológica en el manejo y recuperación de suelos agrícolas degradados y aguas para riego en la pequeña y mediana agricultura en los departamentos de Lima, Áncash, San Martín, Cajamarca, Lambayeque, Junín, Ayacucho, Arequipa, Puno y Ucayali”, con CUI N° 2487112, el cual tiene entre sus objetivos evaluar alternativas tecnológicas para el manejo de suelos y agua en la producción agrícola. En este contexto, el manejo adecuado de la fertilidad del suelo es fundamental para garantizar la sostenibilidad de los sistemas agrícolas, por lo que, el documento aborda los conceptos básicos para la interpretación de los resultados del análisis de suelo y la elaboración de planes de fertilización, con un enfoque específico en los cultivos de café y cacao. Estas prácticas no solo buscan optimizar el uso de fertilizantes y enmiendas, sino también reducir el impacto ambiental y mejorar la rentabilidad de los productores. Este manual está dirigido a técnicos, extensionistas, agricultores y todos aquellos actores involucrados en la cadena productiva de café y cacao, con el objetivo de proporcionar herramientas técnicas que contribuyan al desarrollo de una agricultura más sostenible y competitiva en el Perú.
Weed Species Associated with Cacao Cultivation Exhibiting Phytoremediation Potential for Cadmium and Lead: A Study Based on Bioconcentration and Translocation Factors

The exploration and identification of spontaneous weed species in heavy metal–contaminated soils represent a relevant approach for understanding the role and their potential application in phytoremediation. In cacao cultivation, cadmium contamination poses a significant risk due to the restrictions established for soils and cacao-derived products, thereby threatening productive sustainability and export viability. The objective of this study was to identify weed species associated with cacao cultivation exhibiting accumulation patterns and phytoremediation potential for Cd and Pb, through the assessment of biomass production and the bioconcentration factor (BCF) and translocation factor (TF), in natural conditions. Soil samples were collected from seven cacao-growing zones, and the site with the highest Cd concentration (1.65 mg kg−1) was selected, where ten dominant weed species were identified and evaluated. Significant interspecific differences were observed in biomass production and in Cd and Pb concentrations (p < 0.05). Talinum paniculatum exhibited the highest total biomass (6.15 g) and the highest TF for Cd, whereas Cyperus aggregatus showed the greatest total Cd accumulation (2.68 mg kg−1). BCF and TF values enabled the identification of species with accumulation patterns consistent with Cd phytoextraction (T. paniculatum, C. aggregatus, Pseudelephantopus spiralis, Bidens riparia, Euphorbia heterophylla, and Malvastrum coromandelianum) and with phytostabilization (Ocimum campechianum). For Pb the observed patterns were consistent with potential phytoextractive behavior in B. riparia, P. spiralis, E. heterophylla, Hilleria latifolia, and Acalypha stachyura. Although these results do not constitute functional evidence of remediation, they describe heavy metal accumulation and translocation patterns in native weed species, providing a technical basis for the design of future experimental trials aimed at the sustainable remediation of contaminated soils.
