Abstract
Los abonos orgánicos como los estiércoles, se constituyen en una alternativa para realizar un manejo sostenible del suelo, en zonas como el altiplano de Bolivia en general y en la producción de quinua en particular, sin embargo, es necesario contar con información sobre la capacidad de este abono de proporcionar nitrógeno al suelo y por lo tanto a las plantas. El objetivo del presente trabajo, fue determinar la influencia de la dosis de estiércol ovino y de un bioinsumo (Terrabiosa), en la generación de nitrógeno mineral, en el tiempo. El diseño estadístico aplicado fue el de completamente al azar. Se tuvieron dos factores. El factor A, constituido por dosis de estiércol aplicado al suelo en cantidades de 0, 10 y 20 ton ha-¹ y el factor B, conformado por la presencia y ausencia de un bioinsumo (Terrabisosa). Cada tratamiento con tres repeticiones, haciendo un total de 18 unidades experimentales. La evaluación del nitrógeno mineral fue realizada a los 1, 15, 22, 51, 64, 80, 99, y 125 días después de la incubación. Los resultados muestran que el bioinsumo en forma aislada no tiene efecto en la mineralización del nitrógeno como amonio, mientras que si influyó en la mineralización del nitrato y del nitrógeno mineral. El nitrógeno mineral producido luego de 125 días, fue el doble bajo la aplicación del bioinsumo asociado con el estiércol ovino.
Organic fertilizers such as manure constitute an alternative for sustainable land management in areas as the Bolivian Altiplano in general and for quinoa production in particular, however, it is necessary to have information on the ability of this fertilizer to provide nitrogen to the soil and therefore the plants. The aim of this study was to determine the influence of the dose of sheep manure and a bioinsumo (Terrabiosa) in the generation of mineral nitrogen in time. The statistical design applied was completely random. Two factors were taken. The factor A, consisting of doses of manure applied to the soil in amounts of 0, 10 and 20 t ha-1 and the B factor, consisting of the presence and absence of a bioinsumo (Terrabisosa). Each treatment with three repetitions, with a total of 18 experimental units. Mineral nitrogen assessment was performed at 1, 15, 22, 51, 64, 80, 99, and 125 days after incubation. The results show that the bioinsumo in isolation has no effect on the mineralization of the nitrogen as ammonia, whereas if influenced mineralization and mineral nitrate nitrogen. The mineral nitrogen produced after 125 days, was doubled underthe application of bioinsumo associated with sheep manure.
