CARACTERIZACIÓN Y CALIDAD DE UN ABONO ORGÁNICO FERMENTADO AOF PREPARADO CON RESIDUOS DEL PROCESO DE INDUSTRIALIZACIÓN DE LA PAPA (SOLANUM TUBEROSUM L)

Abstract

The manure production in Colombia has increased in recent years seeking to provide adequate management biodegradable waste generated by agro-industrial processes, the present study evaluated the quality of mineral composition, and characterization of microbial population of a manufactured aof from wasted generated in the industrial processing of potatoes. In Study 2 treatments were: T1 consisted of a mixture of 90% organic material (80% potato waste, sawdust 5%, milling waste 3% and molasses 2%) plus the addition of minerals to form carbonates, phosphates and sulphates in the rate of 10% in T2 only mix the organic material. The trial demonstrated that this material with 75% humidity anaerobic fermentation produces a very strong smell of acid, which decreases as it loses moisture, leaving the mixture in a volume of 50% and changing the smell of an alcoholic fermentation. Given the characteristics of the final product showed T2 high pH values, COO, CIC, CRH and C / N, showing that the potato waste has a good record as organic fertilizer. On the other hand the addition of minerals increases the amounts of these, which are contained naturally in the substrate, giving the compound the added value of a higher percentage of available elements in both cases the supply of nutrients and microorganisms is favorable for plant nutrition.
