The Ecuadorian province of Chimborazo is located in the central area of inter-Andean corridor. The main agroindustries in this province are related to the production of vegetables, meat, ornamental plant, flour of different cereals and wood. The management of the wastes from these agroindustries is not optimized, with the environmental consequences associated. Therefore, the aim of this work was to carry out the characterization of the different organic wastes from agroindustry in order to evaluate their potential use as soil amendments. In this experiment, 27 samples of different types of agroindustrial wastes from vegetable and animal food-processing industry, wood industry and ornamental plant production were evaluated on pH, electrical conductivity, water-soluble anions, organic matter; total organic carbon (Corg); total nitrogen (Nt), C/N ratio, water-soluble carbon (Cw), water-soluble polyphenols, macro and micronutrients, potentially pollutant elements and germination index (GI). The results showed that, in general, the agroindustrial residues were characterized by acidic pH and low EC values and high organic matter contents. The macro and micronutrient and heavy metal concentrations were higher in the animal agroindustrial wastes than in those from vegetable agroindustries. Most of the studied wastes showed values of C/N ratio and of GI, as well as Cw contents, which indicated a lack of stability of their organic matter
