Abstract

The reuse of animal slurry and the utilization of no-tillage can produce economic andenvironmental benefits. In May 2005, a field assay was established in Derio (Spain) to evaluatethe beneficial effects of no-tillage and/or the addition of cow slurry on soil health in a heavy andhumid soil. For comparison purposes, we also studied the effect of conventional tillage andmineral fertilization on soil health. Soil chemical, physical and biological parameters wereanalyzed, as well as forage production and nutritional value. Cow slurry, as compared tomineral fertilizers, enhanced soil biological activity and abundance of earthworms. Despite thesoil compaction derived from no-tillage, soil biological activity was not decreased under notillage. Satisfactory results of forage corn production and nutritional value were obtained underorganic fertilization and no-tillage conditions.
