“…In line with our results Spohn and Stendahl (2022) found significantly lower organic P concentrations and higher C org -to-P org ratios in coarse textured forest soils compared to fine textured ones. Similarly, Chodak and Niklińska (2010) reported that coarse textured sands contained significantly less C org an N t than loamy sands. Next to the texture some other properties of parent materials such as initial concentrations of elements or pH also could have played a role in the observed differences in C org , N t and P org concentrations between various substrate types.…”

“…Organic P is not directly plant available, however there are several mechanisms that enable plants accessing organic P (Richardson et al, 2009). Chodak et al (2021) reported that N-fixing tree species (black locust and black alder) improved capacity of technosols to release P by increasing the activity of phosphatases and enhancing microbial uptake of P. Organic P in soils occurs in a large variety of forms that differ in chemical composition, reactivity and plant availability (Turner et al, 2005). Recent studies suggest that organic P may be an important source of P for plants ( Sulieman and Mühling, 2021).…”

Planted vegetation is considered one of the most important soil-forming factors in the reclamation of degraded post-mining lands for forestry. The objective of this study was to compare the effect of N-fixing tree species and non-N-fixing species on the organic phosphorus (P ) forms in technosols developing from various substrates. Samples were taken from the uppermost layer (depth 0 – 5 cm) of technosols afforested with black locust ( Robinia pseudoaccaccia), black alder ( Alnus glutinosa), silver birch ( Betula pendula) and Scots pine ( Pinus sylvestris). Samples of the tree foliage and the O horizons were taken as well. The studied technosols developed from Quaternary sands (Sands), fly ashes after lignite combustion (Ashes) and Miocene clays (Clays). The soil samples were measured for the contents of labile (P ) and moderately labile organic phosphorus (P ), phosphorus contained in fulvic and humic acids (P and P , respectively) and residual organic phosphorus (P ). The foliage and O horizon samples were measured for the concentrations of C, N and P. The N-fixing trees had higher P concentration in the foliage than non-N-fixing species. However, in the O horizon the highest P concentration was determined under birch and not under N-fixers. The effect of tree species on the organic P (P ) concentrations in the mineral soil was limited with significantly lower P concentrations under pine. Soil under this species contained less P , P and P . However, the percentages of P , P , P , P and P in soil P were nearly the same under all tree species. The largest effect on the P concentration and on the contents of particular P fractions was from the substrate type. Sands contained much less P than the Clays and Ashes but their percentage of P in P was much higher than in two other substrates. We conclude that N-fixing trees do not affect the concentration of labile organic P and the major factor controlling this P fraction is the soil substrate quality.

“…The concentrations of P in litter and soil were extracted by concentrated H 2 SO 4 and determined by molybdenum blue colorimetry. MBP of the soil was analyzed using the fumigation extraction method (Chodak et al, 2021). The APA was measured by the disodium p-nitrophenyl phosphate method (Hou et al, 2015).…”

“…MBP was used to quantify concentrations of P held within soil microbial cells, which play a significant role in P cycling by acting as a source or sink of P i (Achat et al, 2010;Roberts et al, 2013). Outside the cells, acid phosphatase secreted by soil microorganisms plays a critical role in the cycling of soil P and determines the availability of this element (Vincent et al, 1992;Li et al, 2002;Chodak et al, 2021). The findings of this study suggested that soil MBP and APA were the primary factors driving the activation of soil P during litter decomposition.…”

The dynamics of phosphorus (P) in litter–soil systems during litter decomposition across a plantation chronosequence remain to be underinvestigated, especially in terms of the nutrient cycle in plantations. In this study, the P dynamics in a litter–soil system of larch (Larix kaempferi) plantations at three stand ages (10, 25, and 50 years old) were examined through a 4-year in situ decomposition experiment (experiment 1) and a 360-day indoor incubation experiment (experiment 2). The aim of experiment 1 and experiment 2 is to determine the P dynamics in litter and soil, respectively. The results in experiment 1 suggested that litter mass retained 34.1%–42.5% of the initial mass after a 4-year decomposition period, and the turnover time (t0.95) of the decomposition was 11.3, 13.9, and 11.8 years for 10-, 25- and 50-year-old stand larch plantations, respectively. Litter exhibited a net P decrease during the first 180 days, followed by a phase of a net P increase. The lowest P accumulation rate was found in the 25-year-old stand during the P immobilization stage. This immobilization phase was followed by a slow litter P decrease. Highly correlated relations were found between the litter decomposition rate and the initial litter N concentration and C/N, whereas the P accumulation rate was noticeably correlated with the initial litter P and C/P. The results in experiment 2 showed that litter addition promoted the accumulation of the highly labile P (resin P, NaHCO3-Pi, and NaHCO3-Po), as well as moderately labile Pi (NaOH-Pi) in the soil. The findings obtained suggest that soil microbial biomass P and acid phosphatase activity were the primary factors driving the activation of soil P during litter decomposition. These findings would be beneficial to the systematic understanding of the nutrient cycle in plant–soil systems and litter management during the development of larch plantations.

“…The effectiveness and success of phytoremediation can be assessed by evaluating changes in pollutant concentration in soil as well as soil physical and chemical properties. Soil biological properties are also widely used alternative measures of soil reclamation, for example, soil microbial activity, biomass, and extracellular enzyme activity (Chodak et al, 2021; Sroka et al, 2018), or soil fauna activity and biomass (Moradi et al, 2020). Soil biological properties develop along soil physical and chemical transformations but may change faster than soil physicochemical properties; for example, soil microbial biomass (active carbon pool) during chronosequence of grasslands restoration increased faster than total carbon pool (Baer et al, 2002).…”

Hyperaccumulators' ability to take up large quantities of harmful heavy metals from contaminated soils and store them in their foliage makes them promising organisms for bioremediation. Here we demonstrate that some ecotypes of the zinc hyperaccumulator Arabidopsis halleri are more suitable for bioremediation than others, because of their distinct influence on soil biota. In a field experiment, populations originating from metal‐polluted and unpolluted soils were transplanted to a highly contaminated metalliferous site in Southern Poland. Effects of plant ecotypes on soil biota were assessed by measurements of feeding activity of soil fauna (bait‐lamina test) and catabolic activity and functional diversity of soil bacteria underneath A. halleri plants (Biolog® ECO plates). Chemical soil properties, plant morphological parameters, and zinc concentration in shoots and roots were additionally evaluated. Higher soil fauna feeding activity and higher bacterial community functional diversity were found in soils affected by A. halleri plants originating from metallicolous compared to non‐metallicolous ecotypes. Differences in community‐level physiological profiles further evidenced changes in microbial communities in response to plant ecotype. These soil characteristics were positively correlated with plant size. No differences in zinc content in shoots and roots, zinc translocation ratio, and plant morphology were observed between metallicolous and non‐metallicolous plants. Our results indicate strong associations between A. halleri ecotype and soil microbial community properties. In particular, the improvement of soil biological properties by metallicolous accessions should be further explored to optimize hyperaccumulator‐based bioremediation technologies.
