Rumex confertus is known to be one of the most serious invasive weed species infesting meadows, pastures and ruderal lands throughout the Central Europe. Rumex confertus was grown in pot experiments using 8 soil types at 5 concentrations of nitrogen (N) and phosphorus (P). Based on harvest data, the variables, seedlings emergence, root: shoot (R: S) ratio, N and P concentration, chlorophyll content, Relative Colimitation Index (RCI) and dry matter allocation to plant components, were determined. N and P addition stimulated the growth of plants in different soils, as reflected by a significant increase in seedling growth parameters such as total plant biomass and shoot biomass. Across all soil types, emergence of seedlings was negatively affected by very high N, but positively affected by increased P availability. This study indicates that Dystric Arenosol, Entic Podzol, Brunic Arenosol and Calcaric Leptosol are unfavorable for R. confertus growth, excluding R. confertus completely. Moreover, evidence suggests that plant growth is limited by both N and P, therefore R. confertus could be controlled by reducing available N and P content in the soil.

“…In the pot experiment, higher and quicker emergence, together with substantially higher mortality of seedlings were recorded in Litavka than in Malín soil (Hejcman et al 2012). A positive effect of the lime treatment on seedlings was recorded in Litavka soil.…”

“…In the evening of the same day, we sowed 100 seeds of R. obtusifolius in each pot. Three of the most vital seedlings were left in each pot after thinning on 9 th June 2011, in order to determine the effect of soils and Ca and P additives on the growth of this species (Hejcman et al 2012). The pots were regularly watered if necessary to maintain optimal growth conditions during the course of the experiment.…”

Using a pot experiment with slightly acidic and alkaline soils anthropogenically contaminated by As, Cd, Pb, and Zn, we assessed how the establishment of Bryum argenteum and concentrations of elements (P, Ca, Mg, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in its biomass are affected by the pH of the substrate, mobility of trace elements, and by quick lime (CaO) and superphosphate (P) additives. Over one vegetation season, in pots naturally colonised by B. argenteum, a substantially higher cover of B. argenteum was recorded on acidic soil that was heavily contaminated with Cd, Pb, and Zn than on alkaline soil with higher As but lower Cd, Pb, and Zn mobility. In acidic soil, the establishment of B. argenteum was substantially improved by CaO additive, which reduced the mobility of Zn and Cd, and by P additive, which improved the P nutritional status and reduced the extremely high concentrations of many elements (As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in its biomass. Although B. argenteum can be used for the monitoring of soil contamination, concentrations of trace elements in its biomass must be evaluated with caution as they can be affected by total and mobile concentrations of elements in the substrate, and by other soil chemical properties.

“…The specific characteristics of the two long-term heavily As-, Cd-, Pb-, and Zn-contaminated soils are given in previous studies (Hejcman et al 2012Vondráčková et al 2014). The main chemical properties of the soils are as follows: (1) 'Litavka Fluvisol'-354 mg As/kg (in all elements pseudo-total concentrations were extracted with aqua regia), 54 mg Cd/kg, 3305 mg Pb/kg, and 6172 mg Zn/kg, pH CaCl2 6.5, cation exchange capacity (CEC) 109 mmol (+) /kg, and C org 3.6 %, and (2) 'Malín Luvisol'-688 mg As/kg, 11 mg Cd/kg, 98 mg Pb/kg, and 1022 mg Zn/kg, pH CaCl2 7.3, CEC 333 mmol (+) /kg, and C org 2.7 %.…”

Regulation of macro, micro, and toxic element uptake by Salix × smithiana using liming of heavily contaminated soils

et al. 2015

Purpose Willow cultivation in soils heavily contaminated by risk elements is a challenging issue due to phytotoxic effects that restrict plant growth. Liming reduces the mobility of some risk elements in contaminated soils and therefore can be a suitable measure for contaminated soils but can also affect availability of nutrients for planted willows. We investigate how liming affects concentrations of macro, micro, and toxic elements in the organs of willows planted in contaminated soils. Materials and methods We established a 3-year pot experiment with Salix × smithiana planted in weakly acid and alkaline soils anthropogenically seriously contaminated by As, Cd, Pb, and Zn. Soils were both untreated and treated with two doses of lime and dolomite in the first year before planting. We determined biomass production, mortality, and the concentration of macro-and micronutrients and toxic elements in the willows' aboveground organs. Results and discussion Lime application increased biomass production in both soils; dose of lime played an important role for its increase only in alkaline soil. Lime in a higher dose was incompatible with the vitality of just-planted willows in both soils. Doses of dolomite significantly affected the biomass production and mortality of willows, where lower doses caused a permanent decrease of biomass production and mortality in weakly acid soil. The toxicity of Cd and Zn in leaves was recorded in both untreated soils; the latent deficiency of P and deficiency of Fe in leaves was only recorded in weakly acid untreated soil. Conclusions Lime application irrespective of dose with foliar Fe application seemed to be the most suitable measure for increasing biomass production and decreasing toxic elements, especially Cd and Zn, without decreasing the macro-and micronutrients in the aboveground organs of willows in weakly acid soil. In alkaline soil, only higher doses of lime had a positive effect on the studied parameters. Dolomite application is not a suitable measure for planting willows in both contaminated soils. Dolomite in a lower dose impairs the growth of willows in weakly acid soil.
