Determinación de la captura de nitrógeno mediante biocarbón de residuos de poda en un plantel avícola

Abstract

The present work aims at the adsorption of nitrogen in a broiler house using pruning residues, these transformed into biochar for which it was applied to the litter where they are reared, at concentrations of 10, 20 and 30% of the total. of the rice husk which is the material for adsorption of excreta and urine of the animal. Obtaining biochar was done by artisan pyrolysis, using pruning and sawmill waste (shavings). It was evaluated during 3 periods of time at the beginning of the process in which the litter was free of excreta, one month after the entry of the birds and at the end of the rearing period, the total nitrogen of the different concentrations was analyzed, the results indicate that at the end of the experimentation the nitrogen concentration at a biochar percentage of 0% is 1.7 for 10% it is 1.6 for 20% it is 1.2 and for 30% it is 1.2 These data suggest that the higher the concentration of biochar, the greater the loss of nitrogen, this may be due to the type of waste used, the type of pyrolysis that was used, even that the biochar accelerated the degradation process of organic matter which increases the temperature from the ergo bed the nitrogen volatilizes. A cost-benefit analysis was carried out which showed that there are economic losses if biochar is incorporated into the rearing process with a loss of 0.46 cents for every dollar invested. Temperature control is recommended when making biochar, in addition to following biosecurity standards during the aging period.
