“…The amendment provoked a clear improvement in soil quality in the studied soils, as indicated by increases in available nutrients and in biochemical indexes of microbial activity (Madejón et al, 2014). Other authors have observed similar results in different experiments with amendment application (Park et al, 2011), pointing out the benefits of quality material addition for plant productivity.…”

The plantation of fast growing trees in contaminated sites, in combination with the use of organic wastes, could partially solve a dual environmental problem: the disposal of these wastes and the improvement of soil quality in these degraded soils. This study evaluated the effects of two composts amendments on the quantity and quality of Paulownia fortunei biomass and on syngas production by biomass gasification, produced by plants growing on trace elements contaminated soils. Compost increased biomass production to values similar to those produced in non-contaminated soils, due to the improvement in plant nutritional status. Moreover, biomass quality for gasification was increased by compost addition. Trace element accumulation in the biomass was relatively low and not related to biomass production or the gas quality obtained through gasification. Thus, P. fortunei plantations could pose an opportunity to Preprint submitted to Elsevier 2 improve the economic balance of the revegetation of contaminated soils, given that other commercial uses such as food or fodder crop production is not recommended in these soils.

“…Also, the number of leaves rate was increased under P-compost fertilization (0.67 leaf/day) compared to both control (0.56 leaf/day) and cow manure (0.54 leaf/-day) treatments. Similarly, previous studies reported that compost application increased the growth of ryegrass and tall fescue (Festuca arundinacea) (Park et al 2011). Singh and Agrawal (2008) studied the positive effects in some plants (sunflower, maize, barely, etc.)…”

Purpose Date palm (Phoenix dactylifera L.) is one of the predominant fruit trees grown in oases ecosystems (Southern Mediterranean regions) and produces several wastes during practicing cultivation since fruit and bunch thinning is frequently applied. Yet, the valorization of date palm wastes as bioresources has received little attention. The main objective for the present research is to assess palm trees compost (P-compost) as organic fertilizer for alfalfa (Medicago sativa L.). Methods The experiment was carried out in an experimental field involving four replicates and three soil amendment treatments (1) control, conventional mineral fertilizer diammonium phosphate, (2) 30 t ha -1 of cow manure, and (3) 30 t ha -1 of palm tree compost (P-compost). Plots were planted on with alfalfa and the measurements of studied traits (growth, yield, seed yield and minerals uptake) were determined for two crop seasons (2010 and 2011). Results Compared with untreated soil, the palm compost application at 30 t ha -1 improved significantly both organic matter and water retention capacity of the soil and decreased the electrical conductivity (-70%).Furthermore, palm compost supply significantly increased fresh biomass production of alfalfa by 21 and 28%, respectively, during the first and second seasons. Also, it enhanced the grain yield and growth rate (stem length and leafs expansion) of this species. At the first crop season, the palm compost application had a positive impact on minerals nutrition compared to the control treatment, with improving rates of ? 32% for phosphorus, ? 25% for potassium and ? 6% for nitrogen. In addition, these contents were higher than in plants grown under cow manure amendment. However, at the second season, the palm compost improved only P and N contents. Conclusions This preliminary finding suggests that palm compost at moderate dose (30 t ha -1 ) could be highly beneficial for forage plant yield.

“…To improve phytoremediation and because contaminated soils are often poor in available nutrients and often acidic for plants and the associated microbiota, organic and/or inorganic amendments must be used (Park et al, 2011). Moreover, when added to soil these amendments can contribute by their own properties to reducing contaminant levels in water soil solution, by reducing PTE leaching .…”

Mining activities lead to widespread environmental pollution of terrestrial ecosystems due to the presence of metal(loid)s in tailings. These contaminated areas present a health risk and hence need to be rehabilitated. Ex situ methods for soil remediation have been used for a long time but are expensive and disruptive to soil. Phytoremediation techniques for the stabilization or extraction of metal(loid)s could be an efficient alternative as they provide a low-cost and environmentally friendly option. A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPTHowever, due to the often poor nutrient content of these contaminated soils, amendments must be added to enhance plant growth and to improve phytoremediation efficiency. Biochar, a pyrogenic product, is a promising amendment for assisted phytoremediation. The aims of our study were (i) to evaluate the effect of a pinewood biochar on the physicochemical properties of a former mine contaminated technosol, (ii) to assess the mobility and phytoavailability of As and Pb and (iii) to investigate the remediation potential of three willow species (Salix alba, Salix viminalis and Salix purpurea). A greenhouse experiment was conducted with contaminated technosols amended with biochar and garden soil, single or combined, revegetated with the 3 willow species. The physicochemical properties of soil pore water (SPW) as well as metal(loid) concentrations were determined. Plant growth, Salix organ dry weight and metal(loid) uptake were determined in order to evaluate the phytoremediation potential of the three Salix species studied. Biochar increased the pH and electrical conductivity of SPW. Biochar addition had no effect on As mobility but decreased SPW Pb concentration by 70%. For the three Salix species investigated, biochar addition to the polluted soil induced a better growth and a higher dry weight production. In most modalities tested, the metal(loid)A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPTcontent in the Salix organs increased due to the biochar application. Globally, a positive effect of biochar was noticed on the soil qualities (pH and electrical conductivity increase) and plant growth.Metal(loid)s were mostly confined to the roots. Amon...
