Abstract
Con el objetivo de evaluar los elementos nutricionales en la producción del fertilizante biol que fueron obtenidos mediante diversos tipos de insumos y diferentes cantidades de contenido ruminal de bovinos faenados en el Matadero Municipal de Achachicala, se construyó una carpa solar para albergar 18 biodigestores con diferentes tratamientos. Se utilizó el Diseño Completamente al Azar distribuido en un arreglo bifactorial con tres repeticiones. Los factores utilizados fueron la cantidad de contenido ruminal (CR) y tipos de insumos; los tratamientos utilizados fueron Factor A: Contenido ruminal E1=4 kg, E2=5 kg y E3=6 kg; Factor B: insumos D1=leche + melaza, D2=yogurt + melaza; cada tratamiento tuvo 3 repeticiones, para un total de 18 unidades experimentales. Se evaluaron las características químicas: conductividad eléctrica y pH; también se tomaron en cuenta las características nutricionales como contenido de nitrógeno, fósforo, potasio, sodio, calcio, magnesio, sulfuros y sulfatos. Los resultados obtenidos sobre las características químicas fueron pH 6,84; conductividad eléctrica con un valor medio de 1062,33 uScm. En cuanto a las características nutricionales se encontraron que en la comparación de medias en lo referente al componente de nitrógeno, el tratamiento 5 cantidades de CR de 6 kg con un promedio de 256-50 mg/l tuvo mayor descomposición. Por otra parte, en lo referente al factor insumos utilizados en este caso leche + melaza con un promedio de 209,11 mg de N/l, este valor nos indica que este insumo tiene un buen nivel de N. En cuanto al fósforo soluble se encontró un promedio de 168 mg/l no hallándose diferencias significativas; de igual forma para el restante de los componentes nutricionales encontrándose 437,67 mg/l de fósforo total; 1807,72 mg/l de potasio soluble; 1019,72 mg/l de sodio soluble; 465,5 mg/l de calcio soluble; 388 mg/l magnesio soluble; 2778 mg/l de sulfuros; 1173,5 mg/l de sulfatos valores que se asemejan a lo reportado por otras investigaciones similares.
In order to assess the nutritional elements in the production of fertilizer biol obtained with different types of inputs and different amounts of bovine rumen contents from the municipal abattoir of Achachicala. Asolartentwas constructed in orderto accommodate1 8 digesters with differenttreatments, for which the design Completely Randomized distributed on a bivariate basis was used, with three replications. The factors used were the quantity of rumen contents (RC) and types of inputs; treatments used were Factor A, Rumen Content E1= 4 kg, E2 = 5 kg and E3=6 kg; Factor B inputs D1, + molasses milk D2 + molasses yogurt; each treatment had 3 replicates then 18 experimental units were in total. Response variables as chemical characteristics: Electrical conductivity and pH; Nutritional characteristics: Nitrogen, phosphorus, potassium, sodium, calcium, magnesium, sulfides and sulfates were evaluated. The results obtained on the chemical characteristics were pH 6.84; Electrical conductivity with an average value of 1062,33 uS cm. Among the nutritional characteristics, comparing mean of nitrogen content it was seen that treatment 5, with 6kg of RC, had 256-50 mg/l indicating higher decomposition. Moreover, according to the used inputs, the case factor milk + molasses had an average content of 209.11 mg N/l, this value indicates that it has a good level of N. For soluble phosphorus it was found an average of 168 mg/l demonstrating no significaní differences. Likewise, the rest of nutritionalcomponents were found 437,67 mg/l total phosphorus; 1807,72 mg/l of soluble potassium; 1019,72 mg/l of soluble sodium; 465,5 mg/l of soluble calcium; 388 mg/l soluble magnesium; 2778 mg/l of sulfur; 1173,5 mg/l of sulfates; this values resemble were reported by other similar researches.
