Title A name given to the resource Plant Response to Salmon Wastes and Sewage Sludge Used as Organic Fertilizer on Two Degraded Soils Under Greenhouse Conditions Respuesta de Plantas a la Fertilización Orgánica con Residuos de Salmonicultura y Lodos Municipales en Dos Suelos Degradados Bajo Condiciones de Invernadero Creator An entity primarily responsible for making the resource Marco Sandoval, José Celis, Ricardo Barra Description An account of the resource The potential toxicity of urban sewage and farmed salmon sludge, as well as their fertilizer potential, was evaluated by a battery of tests carried out with lettuce (Lactuca sativa L.) and annual ryegrass (Lolium multiflorum Lam.) cv. Winter Star. Wastes were evaluated in a Patagonian soil (Andic cryofluvent) and a granitic soil (Ultic Palexeralf). The treatments were municipal sewage sludge (MSS), salmon ground-farming waste (PSW) and salmon lake-farming waste (LSW) at different rates: 25, 50, 75, 100 and 150 t ha-1. Bioassays in lettuce were conducted for germination index (GI), radicle and hypocotyl structure length. Test in ryegrass were conducted for aboveground biomass yield. The phytotoxicological results from Patagonian soil showed significant differences (P ≤ 0.05) among sludge, where the highest values for GI, radicle and hypocotyl length were for LSW, followed by PSW. Results from granitic soil showed no significant differences among sludge added. In both soils, MSS treatment at application rate of 150 t ha-1 presented the smallest radicle length, not showing development of the hypocotyl structure. Biomass data indicated that MSS, PSW and LSW sludge can be applied at 25 to 150 t ha-1 on Patagonian soil and only LSW sludge on granitic soil. However, its addition should be complemented with N and K inorganic fertilizer to increase pasture yield. MSS and PSW sludge applied at 150 t ha-1 was clearly detrimental for crop yield, especially when applied to granitic soil.En este estudio se evaluó el potencial tóxico y fertilizante de lodos urbanos y biosólidos residuales de salmonicultura, usando para ello lechuga (Lactuca sativa L.) y ballica anual (Lolium multiflorum Lam.) cv. Winter Star. Estos biosólidos fueron adicionados en mezclas a un suelo patagónico (Andic cryofluvent) y a un suelo granítico (Ultic Palexeralf). Los tratamientos fueron lodo municipal (MSS), biosólido de salmonicultura en tierra (PSW) y biosólido de salmonicultura lacustre (LSW) a diferentes tasas: 25, 50, 75, 100 y 150 t ha-1. Los bioensayos con lechuga permitieron medir el índice de germinación (GI), el largo de la radícula y del hipocotilo. Se midió producción de biomasa aérea en los ensayos con ballica. Los datos de fitotoxicidad en suelo patagónico mostraron diferencias significativas (P ≤ 0,05) entre los biosólidos, donde los mayores valores de GI, largo de radícula e hipocotilo correspondieron a LSW, seguido por PSW. Los resultados en suelo granítico no mostraron diferencias estadísticas entre los distintos biosólidos adicionados. En ambos suelos, el tratamiento MSS a una tasa de aplicación igual a 150 t ha-1 presentó las menores longitudes de la radícula, y ningún desarrollo del hipocotilo. Los resultados de biomasa indicaron que MSS, PSW y LSW pueden ser aplicados exitosamente entre 25 a 150 t ha-1 en suelo patagónico y solamente LSW en suelo granítico. No obstante, la adición de estos biosólidos debe complementarse con fertilización inorgánica de N y K para incrementar la producción de pradera. Los biosólidos MSS y PSW adicionados a razón de 150 t ha-1 fueron detrimentales para la pradera, especialmente en el caso del suelo granítico.
