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.
