“…In spite of that, different organic amendments -viz. cotton gin crushed compost and poultry manure, beet vinasse, sewage sludge, organic urban solid refuse, sheep manure, cow manure, rice husk, finely chopped reeds, wheat straw, and licorice (root) dregs (Agassi et al, 1998;Albaladejo et al, 2000;Ojeda et al, 2003;Gonzalez, 2006b, 2008;Nicolás et al, 2012;Karami et al, 2012) -have commonly been used for soil conservation in agricultural and forestry soils.…”

Abstract. Application of organic materials are well known as environmental practices in soil restoration, preserving soil organic matter and recovering degraded soils of arid and semiarid lands. Therefore, the present research focused on evaluating the effectiveness of vinasse, a byproduct mainly of the sugar-ethanol industry, on soil conservation under simulated rainfall. Vinasse can be recycled as a soil amendment due to its organic matter content. Accordingly, the laboratory experiments were conducted by using 0.25 m 2 experimental plots at 20 % slope and rainfall intensity of 72 mm h −1 with 0.5 h duration. The effect of vinasse was investigated on runoff and soil loss control. Experiments were set up as a control (with no amendment) and three treated plots with doses of 0.5, 1, and 1.5 L m −2 of vinasse subjected to simulated rainfall. Laboratory results indicated that vinasse at different levels could not significantly (P > 0.05) decrease the runoff amount and soil loss rate in the study plots compared to untreated plots. The average amounts of minimum runoff volume and soil loss were about 3985 mL and 46 g for the study plot at a 1 L m −2 level of vinasse application.

“…The application of biosolids and proper management, can be possible ways for soil restoration. After biosolids application, plant cover is rapidly established, helping to minimize runoff and reduce water erosion (Rostagno and Sosebee, 2001;Martínez et al, 2003b;Ojeda et al, 2003).…”

Many soils in the Mediterranean region are subjected to progressive degradation as a result of water erosion. A study was carried out to examine the effects of biosolids on a degraded soil. Single doses of 40, 80 and 120 Mg ha -1 of a biosolid were applied to the surface of soil and their effects on its chemical characteristics and on the native vegetation were assessed. Soil macronutrients, micronutrients and heavy metals were tested one and five years after application. Canopy cover, biomass production and mineral composition of native vegetation were also determined. Biosolids increased the content of most nutrients in the soil, although this effect decreased over time. The soil organic matter content did not increase significantly at the beginning of the experiment, although significant differences were observed after five years. The contents of total and extractable heavy metals did not change with time after the application. The native plant biomass production and the canopy cover significantly increased with all the doses applied at the beginning of the experiment, and remained high five years after biosolids application.Additional key words: canopy cover, heavy metals, native plant biomass, soil chemical properties, soil restoration. Resumen Aplicación de un biosólido como enmienda sobre un suelo degradado y calcáreo en un ambiente semiáridoSe ha realizado una experiencia de restauración de un suelo degradado en un ecosistema semiárido. Diferentes dosis de biosólidos (40, 80 and 120 Mg ha -1 ) fueron aplicados una única vez en superficie y se estudiaron sus efectos sobre las principales propiedades químicas del suelo y la cobertura vegetal, producción de biomasa y composición mineral de la vegetación nativa al año y a los cinco años de la aplicación. Las dosis de biosólido incrementaron los contenidos de nutrientes en el suelo, aunque su efecto disminuyó con el tiempo. El contenido de materia orgánica del suelo no experimentó cambio al comienzo de la experiencia, mientras que hubo diferencias significativas entre tratamientos en el último año. El contenido de metales pesados del suelo no varió a lo largo del estudio. La producción de biomasa y cobertura vegetal se incrementaron significativamente con todas las dosis ensayadas y permanecieron así a lo largo de los cinco años del estudio.Palabras clave adicionales: biomasa vegetal, cobertura vegetal, metales pesados, propiedades químicas del suelo, restauración de suelos.

“…In central Spain, Walter et al [5] reported favorable soil and vegetation resulted from the decreased erosion and enhanced water relations that resulted from applications of 40 to 80 Mg biosolids ha −1 . Ojeda et al [6] reported similar results in north-east Spain using fresh biosolids, composted biosolids, and thermally dried biosolids.…”

Biosolids from waste water treatment facilities applied to soils not only add plant nutrients, but also increase infiltration and decrease runoff and erosion. Wet biosolids from New York, NY, were surface applied at 0 to 90 Mg ha −1 dry weight to soils near El Paso, Tex. Simulated rainfall intensities of 16.4 cm hr −1 for 30 minutes applied to 0.5 m 2 soil plots yielded initial infiltration rates of ∼16 cm hr −1 for all plots. Biosolids applications extended the duration of the initially high infiltration rates. After 30 minutes, infiltration rates for bare soil were 3 cm hr −1 without and 10 cm hr −1 with 90 Mg biosolids ha −1 . Applied biosolids, plant litter, surface gravel, and plant base contributed surface cover, which absorbed raindrop energy and reduced erosion. Biosolids increased cumulative infiltration on the vegetated, wet soils more than for the dry or bare soils. Biosolids increased cumulative infiltration from 2 to 6 cm on a bare gravelly soil and from 9.3 to 10.6 cm on a vegetated soil.
