Análisis del efecto del polvo de roca en el almacenamiento de carbono y las variables fisicoquímicas del suelo en manglares de Guayaquil, Ecuador Harry Veintimilla Natalia Molina-Moreira Agrociencias humedales sedimento Remediación bioestimulante materia orgánica Una manera para reducir los gases de efecto invernadero es potencializar el almacenamiento de carbono (C) en el sedimento del manglar. Sin embargo, la contaminación ambiental no permite que los manglares cumplan su función de almacenamiento óptimo. Un bioestimulante llamado polvo de roca (PR) ayuda a remediar el suelo del manglar añadiendo nutrientes. Se analizó el efecto del polvo de roca en el almacenamiento de C a distintos niveles verticales en el horizonte del suelo del manglar del parque lineal Kennedy Norte en Guayaquil, donde se establecieron cuatro áreas de (25 m × 10 m) 250 m2 y se aplicó 1 kg de PR por cada 10 m2. Para analizar el efecto del PR en el almacenamiento de C, se recolectaron muestras de suelo a tres diferentes profundidades (0 a 0,1; 0,2 a 0,3; 0,4 a 0,5) m, durante 180 días con un periodo de muestreo de 30 días. Se realizó un análisis de varianza ANOVA de una vía, del C en comparación con la profundidad, mediante la prueba de Tukey p<0.05. El C, la MO y el N incrementaron sus porcentajes en las profundidades 1 y 2, a los 90 días de aplicación, y luego se mantuvieron estables. No se registró diferencia significativa del porcentaje del C entre las profundidades 1 y 2. Se puede atribuir el incremento de los porcentajes a la época seca y al PR. En cuanto al pH, se mantuvo en un intervalo constante de valores cercanos a neutro. El NH4 tuvo altas tasas de amonificación. Se observó un comportamiento similar en P y S debido a la descarga de efluentes contaminados y por mayor precipitación. 2023 artículo científico 1405-0471 https://www.redalyc.org/articulo.oa?id=61778755006 https://www.redalyc.org/journal/617/61778755006/ https://www.redalyc.org/journal/617/61778755006/html/ https://www.redalyc.org/journal/617/61778755006/61778755006.epub https://www.redalyc.org/journal/617/61778755006/movil 10.21829/myb.2023.2932455 es http://www.redalyc.org/revista.oa?id=617 Madera y Bosques application/pdf Instituto de Ecología, A.C.
