“…After 11 yr, average yield on the 10, 15 and 20 cm topsoil removal treatments amended with manure was 87% of the undisturbed nonamended topsoil. White et al (1997) found that N mineralization potentials were significantly higher 9 yr after biosolid application to degraded rangeland in New Mexico. This indicated that soil fertility remained higher, even though most soil chemical indices were returning to those of untreated plots.…”

. 2003. Crop response to topsoil replacement depth and organic amendment on abandoned natural gas wellsites. Can. J. Soil Sci. 83: [415][416][417][418][419][420][421][422][423]. The reclamation success of abandoned wellsites in agricultural areas depends on their capacity to sustain levels of biomass production similar to those which existed prior to soil disturbance. We examined the effect of four (0, 50, 100 and 150%) topsoil replacement depths (TRD) and five amendment treatments [compost, manure, alfalfa (Medicago sativa L.) hay, wheat (Triticum aestivum L.) straw, check) in the reclamation of three wellsites in south-central Alberta. The largest incremental effect of TRD on spring wheat response in the 4 yr (1997)(1998)(1999)(2000) study occurred between the 0 and 50% treatments. Increasing TRD from 100 to 150% had little impact on crop response. Of the 20 treatments (four TRD × five amendments), the reclamation capacity of the 100% TRD-compost treatment ranked highest, being 19% higher than the baseline treatment (100% TRD-check). The lowest-ranking treatment overall, was the 0% TRD-straw treatment, which yielded 64% of the baseline treatment. Crop yield responses to organic amendments were larger when the recipient soil was lower in organic matter. Positive responses to one-time applications of organic amendments in the short-term (4 yr), advocate their use in soil reclamation of abandoned wellsites, despite a lingering question about the longevity of their beneficial effects. 415-423. Pour réussir, la restauration des puits désaffectés situés dans les zones agricoles dépend de la capacité du sol à produire de manière soutenue une quantité de biomasse analogue à celle produite avant que le sol ait été perturbé. Les auteurs ont étudié l'incidence de l'épaisseur (0, 50, 100 et 150 %) de la couche de sol de surface de remplacement (TRD) et de cinq amendements [compost, fumier, foin de luzerne (Medicago sativa L.), paille de blé (Triticum aestivum L.), témoin) sur la restauration de trois sites dans le centre sud de l'Alberta. Durant l'étude de quatre ans (1997)(1998)(1999)(2000), le plus important effet à la hausse sur le rendement du blé de printemps a été enregistré quand la TRD se situait entre 0 et 50 %. Porter la TRD de 100 à 150 % a peu d'effet sur le rendement de la culture. Sur les 20 traitements (quatre TRD × cinq amendements), c'est celui correspondant à une TRD de 100 % et à l'addition de compost qui a donné les meilleurs résultats, en relevant la bonification du sol de 19 % comparativement au traitement de base (TRD de 100 %-témoin). Les plus piètres résultats sont ceux de la combinaison TRD de 0 %-paille, dont la bonification n'atteignait que 64 % de celle du traitement de base. La culture réagit mieux aux amendements organiques quand le sol bonifié est moins riche en matière organique. La bonne réaction à court terme (4 ans) de la culture à l'application unique d'un amendement organique milite en faveur d'une telle bonification aux sites d'exploitation gazière désaffectés, même si on ignore comb...

“…Biosolids rates from 18 to 45 Mg ha −1 have been recommended for arid rangelands with good agronomic results in terms of grass forage production and soil fertility [13]. Also, residual effects have been observed on soil fertility [14][15][16] and on forage production of arid grasslands [10,11]. However, limited information is available on the residual effects of biosolids application in semiarid grasslands.…”

Single application of biosolids increases forage production on semiarid grasslands. Residual effects of biosolids on forage production have been scarcely measured in semiarid grasslands. The objective was to evaluate the residual effects of biosolids application on forage production of blue grama (Bouteloua gracilis (Willd. ex Kunth) Lag. ex Griffiths) and other grasses at a semiarid grassland in Jalisco, Mexico. The study was performed at shortgrass prairie in northeast Jalisco. Field plots were selected to include blue grama plants before rainy season in 2002. Aerobic biosolids were applied at 0 (control), 15, 30, 45, 60, 75, or 90 dry Mg ha −1 under a completely random design with five replications. Forage production was estimated by clipping at the end of the growing season during five years. Data analysis was performed with linear mixed model and repeated measures. Forage production was influenced by a rate × year × species interaction ( = 0.0001). Blue grama forage production increased with increasing biosolids rates during all years, with the magnitude of this response varying among years. Forage production of other grass species slightly decreased with biosolids application. Single biosolids application had a residual effect on forage production throughout five years in semiarid grasslands.

“…The negative impacts of the cutting and filling operations on soil productivity will need to be remediated by restoring natural ecological functions to the affected soils. Organic matter additions to the soil, such as biosolids and composts, decrease the bulk density of soils, increase infiltration rates and porosity, and contribute to better soil structure (Ruehlmann and Körschens 2009;Sloan and Cawthon 2003;White et al 1997). The use of cover crops can also be an important management tool for protecting soils from erosion during dormant seasons and for reestablishing key soil quality indicators (Abdollahi and Munkholm 2014;Stavi et al 2012).…”
