Resumen

Objetivo. Se estudió la actividad de la deshidrogenasa tras la activación biológica del biocarbón por los microorganismos nativos del suelo. El objetivo principal era mejorar las propiedades del biocarbón mediante su activación y hacerlo más amigable para la microflora del suelo. Materiales y métodos. La activación se logró mediante la aireación del suelo con la solución durante dos semanas. No se aplicó ningún inóculo especial de microorganismos. Se prepararon los siguientes tratamientos en cuatro réplicas: biocarbón crudo convencional (BR), biocarbón activado (BA), fertilizante mineral DAM 390 (NF) y control (C). Se utilizó una prueba estadística para comparar las medias de los tratamientos (Fisher p≤0.05; programa STATISTICA 12.0; StatSoft software Inc., Tulsa, Oklahoma, USA). Resultados. Se encontraron diferencias estadísticamente significativas en la actividad deshidrogenasa entre los tratamientos BR, BA y C. La aplicación de fertilizantes minerales tuvo un efecto negativo y se observó un aumento de la lixiviación de nitrógeno. Conclusiones. La activación del biocarbón es un método adecuado para mejorar la condición de la biota del suelo en comparación con el biocarbón convencional.
