Resumen
[ES] Hoy en día la agricultura de conservación se considera como una posible solución que integra la protección del medio ambiente y la producción sostenible de productos de calidad en países africanos como Burundi, donde las condiciones sociales, económicas, tecnológicas y ambientales son desfavorables. En este tipo de agricultura se potencia el reciclaje y la reutilización de fuentes locales y asequibles de materia orgánica y nutrientes. En el presente trabajo se evalúa el efecto de enmiendas orgánicas (Bokashi, biochar y compost) asequibles en Ngozi (Burundi) sobre el desarrollo de plantas tipo de girasol y guisante. Todas las enmiendas orgánicas incrementaron la biomasa, el carbono y el nitrógeno, cosechados en el girasol, con respecto a plantas control sin enmiendas. Sin embargo, sólo las plantas de guisante incubadas con bokashi mostraron una producción significativamente distinta al control. A partir de los resultados de este estudio se concluye que el bokashi fue la enmienda orgánica más adecuada para promover el crecimiento de plantas en sistemas agrícolas con suelos de baja fertilidad.
[EN] Currently, agriculture of conservation is considered as a potential solution in African countries like Burundi, where social, economic, technical and environmental conditions are unfavorable. Under this agriculture type, the environmental protection and the sustainable production of quality food are integrated. This type of agriculture promotes the recycling and reutilization of locally available sources of organic matter and nutrients. In this study, the effects of different organic amendments (Bokashi, biochar and compost) availables in Ngozi (Burundi) on the production of sunflower and pea, as plant models, have been evaluated in a lab incubation experiment. The application of these organic sources increased the production and harvested carbon and nitrogen in sunflower plants respect to control plants without any amendment. However, only the production and harvested carbon and nitrogen of pea plants was increased with bokashi. Results of this study highlight that bokashi is an adequate source of organic matter and nutrients which might increase the production of crops in low fertile soils in areas with restricted access to fertilizers.
