“…Among the latter, Robinia pseudoacacia L., of de Fabaceae family, is also a fast-growing species, with a certain degree of drought tolerance, capable of sprouting from the stumps and with a high nitrogen fixing capacity [6]. For these reasons, Robinia is considered suitable for cultivation in SRC in some areas of Europe [7,8], although it is also considered an invasive species introduced into Europe in the 17th century [9].…”

This study aims to quantify the potential contribution of nutrients derived from leaf litter in a short rotation coppice plantation which includes monocultures of the species Populus alba (PA) and Robina pseudoacacia (RP) as well as a mixture of 50PA:50RP, in the middle of the rotation. The P. alba monoculture was that which provided the most leaf litter (3.37 mg ha−1 yr−1), followed by the 50PA:50RP mixture (2.82 mg ha−1 yr−1) and finally the R. pseudoacacia monoculture (2.55 mg ha−1 yr−1). In addition to producing more litterfall, leaves were shed later in the P. alba monoculture later (December) than in the R. pseudoacacia monoculture (October) or the mix (throughout the fall). In terms of macronutrient supply per hectare, the contributions derived from leaf litter were higher for K, P and Mg in the case of P. alba and for N in R. pseudoacacia, the mix presenting the highest Ca content and intermediate concentrations for the rest of the nutrients. In addition, other factors such as C:N or N:MO ratios, as well as the specific characteristics of the soil, can have an important impact on the final contribution of these inputs. The carbon contribution derived from leaf fall was higher in the P. alba monoculture (1.5 mg ha−1 yr−1), intermediate in the mixed plot (1.3 mg ha−1 yr−1) and slightly lower for the R. pseudoacacia monoculture (1.3 mg ha−1 yr−1). Given these different strategies of monocultures with regard to the dynamism of the main nutrients, species mixing would appear to be suitable option to achieve a potential reduction in mineral fertilization in these plantations.

“…In the case of P, its availability was low in all plots and was highly influenced by adsorption processes, which are very intense in these mine spoils (Monterroso et al ., ; Slazak & Freese, ). Mine waste materials suffer weathering over time; therefore, mine soils are enriched in Fe and Al oxyhydroxides (Uzarowicz & Skiba, ), which have high P adsorption capacity at low pH (Monterroso et al ., ; Wang et al ., ).…”

Evolution of Chemical Characteristics of Technosols in an Afforested Coal Mine Dump over a 20‐year Period

et al. 2016

Coal mining in areas containing pyritic materials frequently leads to a remarkable impact on the environment because of sulphide oxidation. We studied the evolution of chemical characteristics of Technosols derived from sterile materials, in a lignite mine located in As Pontes (northwest Spain), over a 20-year period. Three plots, which had different management practices, were selected. The mine spoil was deposited randomly in two of the plots (CSP with low S concentration and CSA with high S concentration), while it was selectively managed in the other one (P206). Twenty years after the first sampling, CSA continued to show the highest acidity (pH water 3•7-3•9), whereas the lowest acidity was that of P206 (pH water 5•0). Regarding the surface layer, C increased 1•1% in P206, 0•3% in CSP and 0•2% in CSA. Nitrogen increased 1% in P206. The C/N ratio increased in all plots. Phosphorus, Ca, Mg, K and effective cation exchange capacity decreased in 2002 and experienced a slight increase in 2012. Exchangeable Al and Al saturation increased in CSP and P206 and decreased in CSA. Electric conductivity levels of Ca, Mg, Na, Al and SO 4 2À concentrations decreased in the soil solution in all plots during the 20-year period. Twenty years after the first monitoring, the plots that were built based on selective management of the mine spoil showed lower acidity and acidity-derived consequences. These facts confirm the necessity of an appropriate selection of sterile materials, avoiding the placement of pyrite-rich spoils on the surface or near-surface zones, which is essential to facilitate proper restoration of this kind of dumping areas.

“…Phosphorus was a limiting factor in restoring soil fertility on a newly reclaimed land after coal mining in China and dicalcium phosphate was identified as the main source of variation in the capacity of soil to supply P (Chen et al 1998). Some post-mining soils in northeast Germany were identified as P-deficient and less P saturation in soils was coupled with rather small contents of oxalate extractable iron and aluminum (Slazak and Freese 2015). In some reclaimed mine sites in the Appalachian region, plant-available P (i.e., P measured using bicarbonate extraction) was 32% lower than in a managed forest (Simmons and Currie 2005).…”

Phosphorus availability and fractionation vary among forest site types in reconstructed oil sands soils

We investigated relationships between phosphorus (P) availability and fractionation and growth of lodgepole pine (Pinus contorta var. latifolia Engelm. ex S. Watson) and white spruce (Picea glauca (Moench) Voss) in the Athabasca oil sands region. The study sites had peat – mineral soil mix (PMM) as cover soil over a tailings sand substrate planted to pine or an overburden substrate planted to spruce. Available P was determined using a modified Kelowna extraction and sequentially extracted to obtain exchangeable, Fe- and Al-bound, Ca- and Mg-bound, organic, and residual P. The organic P content in PMM explained 83% and 65% of the variations in available P in the pine and spruce sites, respectively. Phosphorus bound to Fe and Al in PMM was also positively related to available P on pine sites (p < 0.001) but not on spruce sites. Available P in PMM was correlated with aboveground biomass increment of spruce (p < 0.05) and explained 78% of the variation in foliar P. Foliar P in both pine and spruce was lower than the adequate level for tree growth. Low foliar P and available P in PMM affect the successful establishment of pine and spruce trees on the reclaimed sites, and proper P nutrition management is important to overcome P limitation in reclaimed soils.
