CHARACTERIZATION OF INDUSTRIAL SLUDGES TO BE USED AS ORGANIC FERTILIZER

| description | The incorporation of organic fertilizers to the soil turns its structure granular and/or crumbly, thus favouring both water retention and distribution and root and microorganism breathing, and adding not only organic carbon but also other macronutrients. Industrial sludge samples -aerobically treated effluents- from a jelly factory were used. The objective of this work is to characterize those sludges with the necessary precision to allow a feasibility analysis of their use as organic fertilizers under the prevailing laws. Two spraydried samples a week -taken at random- were analyzed during a month. Analyses (in quintuplicate) were as follows: Apparent Density, Actual Density, pH, Carbon, Nitrogen, Phosphorus, Calcium and Potassium. Statistical analyses for each variable (Mann-Whitney Test, Kolmogorov-Smirnov Test, Levene Statistic and Anova) were performed in two temporal senses: a transverse (every week) one and a longitudinal (along four weeks) one. Each variable was found not to depend on the sampling place or time, sludges chemical composition being considered stable. |

La incorporación de fertilizantes orgánicos al suelo hace que la estructura se vuelva granular y/o migajosa, lo cual favorece la retención y distribución del agua y la respiración de raíces y microorganismos. Además, no solo se agrega carbono orgánico al suelo, sino también otros macronutrientes. Se utilizaron muestras de barros industriales provenientes del tratamiento aeróbico de efluentes de una fábrica de gelatina. El objetivo de este trabajo es caracterizar dichos barros con la precisión necesaria para posibilitar el análisis de factibilidad de su uso como fertilizante orgánico en el marco de la legislación vigente. Se analizaron dos muestras al azar por semana (provistas secas en forma spray), durante un mes seguido. Los análisis (quintuplicado para cada muestra) fueron: Densidad Aparente, Densidad Real, pH, Carbono, Nitrógeno, Fósforo, Calcio y Potasio. El análisis estad ístico de las determinaciones de cada variable se realizó en dos sentidos temporales, uno transversal (en cada semana) y otro longitudinal (a lo largo de las cuatro semanas).
