Efecto de lixiviados de plantas de tratamiento de residuos sólidos en la producción de plantones de Cedrela sp.

Abstract

The study developed in the laboratory and nursery of the Faculty of Agricultural Sciences, where the characteristics and effect of leachates from solid waste treatment plants were evaluated in the production of seedlings of Cedrela sp. The leachate came from the solid waste treatment plants in the districts of Pangoa and Satipo. Three leachates were considered: Satipo compost leachate, Pangoa compost leachate and Satipo solid waste leachate; and two dilutions of 50 and 100%, previously treated under the anaerobic bioreactor system to improve its properties and use as a biofertilizer. The leachate and substrate were evaluated: pH, electrical conductivity, phosphorus, potassium, calcium and magnesium. The treatments were applied to seedlings of Cedrela sp.; The effect of the application on the plant was evaluated, such as height, stem diameter, mortality, number and weight of leaves. The research was descriptive and experimental, application level. The population consisted of 360 plants, 20 plants per experimental unit; obtaining as a result that there were significant differences between the treatments for the variables of mortality, growth, stem diameter and leaf weight, for the number of leaves lower values were found in the solid waste leaching treatment. The leachate applied to the soil influences the pH, salinity, the content of phosphorus, potassium, calcium and magnesium, however diluted, the influence is excepted in the pH and salinity.
