Resumen
[ES] Numerosos estudios han demostrado el potencial que tiene el compost tea en la agricultura derivado de sus efectos positivos en la estimulación del crecimiento de las plantas y su papel como supresor de plagas y enfermedades. Sin embargo, todavía son escasos los estudios diseñados para evaluar las características agroquímicas de distintos compost teas hechos con distintas fuentes de materia orgánica. En este estudio se determinaron las características agroquímicas y los efectos en el crecimiento de lechuga (Lactuca sativa), girasol (Helianthus annuus) y guisantes (Pisum sativum) de distintos compost teas hechos con materia orgánica de orígenes diversos y en presencia y ausencia de ceniza. Los resultados que se obtuvieron fueron claramente superiores con el uso de compost tea con respeto al control, así mismo el uso de ceniza en los compost teas aumentó los niveles de amonio, nitrato y fosforo, y el pH en los compost teas.

However, few studies have been designed to analyze the agrochemical characteristics properties of teas produced from different sources of organic matter with or without ashes. This study evaluates the effects of compost teas from different sources of organic matter and with the presence or absence of ash in lettuce (Lactuca sativa), sunflower (Helianthus annuus) and peas (Pisum sativum). The results that were obtained were distorted with the use of compost tea with respect to control, as well as the use of ash in tea compost increased levels of ammonium, nitrate and phosphorus, and pH in tea compost.
