| description | One way to reduce greenhouse gas emissions is to enhance Carbon (C) storage in mangrove sediment. However, environmental pollution hampers the optimal storage function of mangroves. A bio-stimulant named rock dust (RD) aids in remediating mangrove soil by adding nutrients. The effect of rock dust on C storage was analyzed vertically across the soil horizon in the Kennedy Norte Linear Park mangrove in Guayaquil. Four (25 m × 10 m) 250 m2 areas were established, with 1 kg of RD applied every 10 m2. To analyze the impact of RD on C storage, soil samples were collected at three different depths (0 m to 0.1 m / 0.2 m to 0.3 m / 0.4 m to 0.5 m) over 180 days, with sampling intervals of 30 days. A one-way ANOVA analysis was conducted on C in relation to depth, using the Tukey test at p < 0.05. Carbon (C), organic matter (OM), and nitrogen (N) percentages increased in depths 1 and 2 at 90 days after application and remained stable after that. No significant difference in C percentage between depths 1 and 2 was reported. The percentage increase can be attributed to the dry season and RD application. As for pH, it remained within a constant range of values near neutral. NH4 exhibited high ammonification rates. Similar behavior was observed in P and S due to contaminated effluent discharge and higher precipitation. |

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.
