Assessment of a sargassum-based liquid biofertilizer for enhanced banana cultivation in small-scale family farms
(Elsevier, 2025) Rodríguez Rodríguez, Yaset
The substantial influxes of pelagic Sargassum spp. along Caribbean coasts pose environmental challenges for the region's countries, but also offer opportunities for sustainable valorization. This research develops and evaluates a Sargassum-Based Liquid Biofertilizer (SBLB) produced via anaerobic fermentation, uniquely reducing heavy metal content (e.g., arsenic from 61.6 to 4.08 mg/kg) while retaining beneficial nutrients and microorganisms. This biofertilizer was applied to banana cultivation in Dominican small-scale family farms, SBLB enhanced leaf emission (p < 0.05 in two of three farms) compared to a traditional biofertilizer (BLB) and maintained Black Sigatoka disease below intervention thresholds, matching BLB performance. Chemical and microbiological analyses confirmed SBLB’s safety and efficacy, positioning it as a sustainable alternative to chemical fertilizers. This approach mitigates Sargassum waste and supports organic farming, offering a replicable model for coastal agricultural systems.
Pensar el país desde la academia : el legado de Julio Sánchez Maríñez
(Santo Domingo : Acento, 2025) Toribio, Magaly
Necesidad de más voces como la suya. Más líderes que comprendan que la educación no es un gasto, sino una inversión de larga duración. Que las aulas son más poderosas que las armas, y que el saber compartido es el único legado verdaderamente transformador.

El tema de las “señales” que hemos tratado en los dos últimos artículos sigue generando reflexiones entre los lectores. Quiero destacar el valioso aporte del Dr. Roberto Figueredo, hijo de un primo fallecido, quien subraya la importancia del examen clínico: “Comparto los criterios que expones en tu artículo. Como médico, siempre insisto en la relevancia del método clínico, donde escuchar atentamente al paciente y atender los ‘síntomas de alerta’ es fundamental. Realizar un examen físico minucioso nos permite orientar adecuadamente el diagnóstico, que luego puede confirmarse —o no— con estudios complementarios, muchas veces costosos e innecesarios. En esta etapa de la vida, entender los cambios propios y significativos de nuestro cuerpo nos ayuda a mantener un estilo de vida más saludable.
