“…NO -N 3 − on the 50th and 100th day increased at lower concentration (15 mg Cd kg -1 ) and decreased at higher concentration (30 mg Cd kg -1 ). This is consistent with Xue et al [23] who found there was a higher soil NO -N It was reported that application of benomyl may kill or inhibit some fungi and lower microbial respiration and biomass. However, benomyl may also provide a substrate and energy for live microorganisms resulting in microorganism activity enhancement.…”

“…), with average annual precipitation and average annual temperature of 820 mm and 7.2 • C, respectively. The soil was classified as Stagnic Luvisol (WRB, 2015). Before the beginning of the field trial, the total HM concentrations (in mg kg −1 ) were: As -109, Cd -3.1, Cr -27, Cu -24, Hg -0.3, Ni -18, Pb -416, Zn -206 (Dietzsch et al, 2011), exceeding the precautionary values of the German Federal Soil Protection Ordinance (BBodSchV, 1999) for grassland.…”

“…Among the best performing phytomanagement options, the short rotation coppice (SRC) with HM tolerant woody plants has been proven to stabilize HMs, reduce the soil toxicity and restore ecosystem functionality ( Mench et al, 2010 ). Despite the importance of soil microbial communities as mediators for fundamental ecosystem functions, changes in functional genes encoding enzymes for carbon (C), nitrogen (N), phosphorus (P), and sulfur (S) cycles and related soil functions under phytomanagement have been addressed only by few studies ( Epelde et al, 2010 ; Xue et al, 2015 , 2018 ). The scarcity of data makes it still be unclear that, to what extent, microbial functional gene shifts under phytomanagement depend on types, concentration and availability of HM, and whether it is site-specific.…”

Phytomanagement Reduces Metal Availability and Microbial Metal Resistance in a Metal Contaminated Soil

Short rotation coppice (SRC) with metal tolerant plants may attenuate the pollution of excessive elements with potential toxicity in soils, while preserving soil resources and functionality. Here, we investigated effects of 6 years phytomanagement with willow SRC on properties including heavy metal levels, toxicity tested by BioTox, microbial biomass, enzyme activities, and functional gene abundances measured by GeoChip of soils contaminated by As, Cd, Pb and Zn, as compared to the same soils under nonmanaged mixed grassland representing no intervention treatment (Unt). Though metal total concentrations did not differ by SRC and Unt, SRC soils had lower metal availability and toxicity, higher organic carbon, microbial biomass, phosphatase, urease and protease activities, as compared to Unt soils. Significantly reduced abundances of genes encoding resistances to various metals and antibiotics were observed in SRC, likely attributed to reduced metal selective pressure based on less heavy metal availability and soil toxicity. SRC also significantly reduced abundances of genes involved in nitrogen, phosphorus, and sulfur cycles, possibly due to the willow induced selection. Overall, while the SRC phytomanagement did not reduce the total heavy metal concentrations in soils, it decreased the heavy metal availability and soil toxicity, which in turn led to less metal selective pressure on microbial communities. The SRC phytomanagement also reduced the abundances of nutrient cycling genes from microbial communities, possibly due to intense plant nutrient uptake that depleted soil nitrogen and phosphorus availability, and thus site-specific practices should be considered to improve the soil nutrient supply for phytomanagement plants.

The study has established the regularities of distribution of certain physiological groups of microbial cenosis in conditions of growing of fruit and energy plants. In case of willow, the numbers of ammonifiers, micromycetes, actinomycetes, cellulolytic and oligonitrophilic microorganisms were observed to reduce compared to the control. In case of apple-trees, the number of microorganisms was higher but still within the control values. Growing of willows leads to stabilization of soil solution reaction, higher concentration of ammonium nitrogen, and lower concentration of nitrate nitrogen and potassium, compared with the control. We have established decreased concentrations of humus vs. control in both cases-growing of willows and apple-trees, which figure correlates with the number of pedotrophs. Notwithstanding the lowered number of some physiological groups of microorganisms, the soil with willows was characterized by highly intensive mineralization processes, in particular those of transformation of organic matters. An open-field long-term fertilization experiment was set up during 2011 with willow (Salix triandra x Salix viminalis 'Inger'), grown as an energy crop. The brown forest soil was treated during June 2011, May 2013, and May 2016 with municipal biocompost (MBC), municipal sewage sludge compost (MSSC), willow ash (WA) and sulfuric urea (SU) and two times (2011, 2013) with rhyolite tuff (RT). Thus, the most indicative changes in the soil microbiota against the control plot were found in case of the use of municipal sewage sludge compost; rise in the number of intestinal bacteria, ammonifiers, micromycetes and actinomycetes. In case of the use of municipal biocompost rise in the levels of intestinal bacteria, microscopic fungi, actinomycetes, pedotrophs and cellulolytic bacteria were found. While calculating the mineralization/immobilization index, it was shown that the most significant deviation from the control plot was found in rhyolite tuff treated soil-a decrease by 6 times, and in case of willow ash by 2.3 times, which proves the inhibition of mineralization of the organic substances in the soil.
