The objective of the research was to apply compost based on municipal organic waste to recover degraded soils in the Peruvian Amazon. An area of 2500 m2 was considered, where five points were sampled and two calicata were obtained for each one. The depth of the calicata was 20 cm. and, subsequently, 1 kg of degraded soil was taken for physical, chemical and biological analysis. Four treatments were used (T1: Control, T2: MOW, 250 mg., T3: MOW, 500 mg and T4: MOW, 750 mg.) with 5 replications for each treatment with a total of 20 experimental units. The organic matter was composed of egg shell, orange, banana, stems, leaves and roots to be segregated and crushed until 12,000 kg. were obtained. Mountain microorganisms (MM) were added to obtain 3,000 kg., after which the chemical analysis was carried out. Maize (Zea mays. L) was used as an indicator plant, which germinated for 30 days to demonstrate the recovery of degraded soils and variability in agronomic parameters. Significant differences between treatments were measured with Duncan. It is concluded that there is a significant improvement in the recovery of degraded soils using MOW. Treatments 3 and 4 show significant relevance and differences with respect to macronutrients. Finally, in terms of morpho-physiological analysis, treatment 4 shows greater growth in stem, number, length and width of leaves. Therefore, the use of municipal organic waste could be an efficient and effective alternative for the recovery of contaminated soils.
