Evaluación de la calidad del abono (pollinaza) en distintos periodos de degradación con microorganismos eficientes

Abstract

The research was carried out in the poultry farm BIOAVES S.A. located in La Troncal canton in Ruidoso Chico neighborhood. The objective was to evaluate the quality of the fertilizer (pollinaza) in different degradation periods with efficient microorganisms (EM-1). The composting was made in wooden boxes of square shape of one meter per side. A total of 640 kg of pollinaza and inputs were used in 16 experimental units, 4 control units and 12 experimental units, which were inoculated with different doses of 100 ml, 200 ml and 300 ml of EM-1. The statistical analysis used a Random Complementary Design, analysis of variance, the test of comparison of averages and regression. The results obtained at 4 weeks showed that when inoculating 300 ml of EM-1reduced the organic matter of the pollinaza from 58 % to 57 % lowered the pH from 8,5 to 7,74, nitrogen increased from 1,08% to 2,20%, potassium increased from 0,28 % to 3,48 %, phosphorus increased from 1,48 % to 2,83 %, carbon decreased from 33,06 % to 27,84 % and the carbon/nitrogen ratio decreased from 28,50 to 13,39. The results obtained at 8 weeks indicate that when inoculating 300 ml of EM-1reduced pollinaza organic matter from 57 % to 48% and lowered the pH from 8,52 to 7,00, nitrogen increased from 1,08 % to 2,23 %, potassium increased from 0,28 % to 3,50 %, phosphorus increased from 1,48 % to 2,86 %, carbon decreased from 33,06 % to 22, 04 % and the carbon/nitrogen ratio decreased from 28,50 to 11,27 compared to control treatment. In conclusion, the T3 treatment to which 300 ml of EM-1 was added has a greater effect on the degradation of the pollinaza at 60 days.
