ABSTRACT 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.
