Efecto de la aplicación de un vermicompost en las propiedades químicas de un suelo salino-sódico del semiárido venezolano

A 10% application of vermicompost significantly improved the chemical properties of a saline-sodic soil in Venezuela's semi-arid region, reducing electrical conductivity by 62%, pH from 8.3 to 7.5, and exchangeable sodium percentage (ESP) by 50% over 28 days. The study, conducted on soil samples from Coro's Cebollal, demonstrated that vermicompost—composed of Eisenia foetida worms, food waste, coffee prunings, banana pseudostems, and horse manure—serves as an effective organic amendment for mitigating salinity in degraded soils. Researchers compared the impact of three vermicompost doses (1%, 5%, and 10%) against a control, measuring key soil parameters at weekly intervals. The findings highlight vermicompost's potential as a sustainable strategy for restoring saline-sodic soils in arid ecosystems.
