| description | Two earthworm species, one exotic (Pontoscolex corethrurus) and the other one native (Glossoscolecidae sp.) from Veracruz, Mexico, were cultivated under laboratory conditions, to collect their castings every 48 h, measure cast production rates and their effects on soil chemical conditions and the concentration of several plant-available nutrients. Both species were cultivated in an Alfisol (La Víbora) and P. corethrurus was also raised in two other soil types, a Vertisol (Plan de las Hayas) and an Andosol (Los Tuxtlas), to measure pH, C, N, C/N, NO3, NH4, Na, K, Ca, Mg, CIC, available- totaland resin-P, Al, Fe, Cu, Zn, Mn in the casts and control soil. P. corethrurus surface cast production was highest in soils with low organic matter content. In the Alfisol, Glossoscolecidae sp. produced less casts than P. corethrurus, but promoted the availability of most plant nutrients, especially K, Na Mg, Mn, Fe, K and NH4. Pontoscolex corethrurus promoted the concentration of most parameters compared with the control in the Andosol and Vertisol; in the Alfisol, about half the parameters were significantly affected. Pontoscolex corethrurus has a high capacity to adapt to different soils and modify their chemical characteristics, promoting the availability of several plant nutrients; this is especially important in organic matter-poor soils, such as the Alfisol. |

Dos lombrices tropicales, una exótica (Pontoscolex corethrurus) y otra nativa (Glossoscolecidae sp.) de Veracruz, México, fueron cultivadas en condiciones de laboratorio para colectar sus respectivos turrículos (deyecciones) cada 48 horas, medir su tasa de producción y el efecto que ejercen sobre varios parámetros químicos en el suelo excretado. Ambas especies fueron cultivadas en un Lixisol (La Víbora) y P. corethrurus lo fue también en otros dos tipos de suelo, un Vertisol (Plan de las Hayas) y un Andosol (Los Tuxtlas). Los parámetros químicos medidos en los turrículos y en suelo testigo (control) fueron los siguientes: pH, C, N, C/N, NO3, NH4, Na, K, Ca, Mg, CIC, P-asimilable, P-Total, P-Resinas, Al, Fe, Cu, Zn, Mn. Para P. corethrurus la producción de turrículos superficiales fue más alta en los suelos con menor contenido de MO. En el Lixisol, Glossoscolecidae sp. produjo menor cantidad de turrículos comparada con P. corethrurus, pero promovió una disponibilidad mayor, especialmente de K, Na Mg, Mn, Fe, K y NH4. Pontoscolex corethrurus promovió también la concentración de la mayor parte de los parámetros estudiados con respecto al suelo control, tanto en el Andosol como en el Vertisol; en el Lixisol, esta especie incrementó la concentración en la mitad de los parámetros. Pontoscolex corethrurus tiene una capacidad alta de adaptarse a diferentes suelos y de modificar sus características químicas, promoviendo la disponibilidad de diversos elementos esenciales para el crecimiento vegetal; eso es especialmente importante en los suelos más pobres como el Lixisol.
