Contenido nutricional del compost a partir de residuos agropecuarios en la ESPAM MFL

The purpose of this study was to evaluate the nutritional content of the compost made with agricultural waste to determine its quality. Four treatments were evaluated plus a control with different formulations of agricultural waste material, the content of N, P, K, Ca, Mg and S (mg/kg), CE (dS/m), MO (%), pH, temperature and humidity, to determine the quality of the compost according to the Chilean regulation Nch2880. Data were analyzed using the SPSS-IBM Statistics 26 program and subjected to ANOVA statistical analysis and Tukey's test at 5%. The results determined that the temperature and humidity parameters did not have significant differences during the composting process in each treatment (p>0.05), reaching the highest values of temperature in week 4 and of pH in week 6. The macronutrient content, were significantly influenced (p<0.05) by the amount of material applied in each treatment, T1 had a higher concentration of N (13,500 mg/kg), while T2 had a higher concentration of P (12,550 mg/kg), in addition to T3 where it had the highest concentration of K, Ca, Mg and S (20050, 56850, 11500 and 15200 mg/kg respectively). These values showed that all the treatments are typified for a class B quality compost, because they contain a high salt content; however, T4 has high concentrations of macronutrients, making it a better alternative for use as a substrate. The results were disseminated to the technical and administrative staff of CIIDEA, generating a guide for the use of agricultural residues.
