“…In the case of the acidic soil, hydrolysis of Cr(III) is less pronounced, and hence its mobility increases. Similar findings by Pukalchik et al (2018) suggest that solution pH values can significantly affect metal species distribution and, as a result, metal sorption in soil. Changes in pH influence directly humic products, because of their functional groups, such as carboxyl, phenolic, and amino, are pH-dependent (Pukalchik et al 2018), which may result in Fe(III) reduction to Fe(II) (Mejia, Roden, and Ginder-Vogel 2016).…”

Stabilization capacity of 5% by weight lignite added in three particle size ranges (<0.5; 0.5-1.0 and 1.0-2.0 mm) to acidic (pH = 5.0) or calcareous (pH = 7.7) sandy soil samples of <2 mm grain size artificially contaminated with 375 mg/kg Cr(III) was assessed through fitfor-purpose leaching tests performed with CH 3 COOH, NH 2 OH·HCl and EDTA. About 90% and 60% of Cr(III) were immobilized in calcareous and acidic soils per se, respectively. Although the point of zero charge measurements (pH pZC ≈4.5) indicated that lignite could effectively bind positively charged Cr hydroxo complexes at the pH of the calcareous soil, the application of lignite is unnecessary due to the low solubility of these species. Although the acidic soil mobilizes Cr, the addition of lignite has been proven to stabilize it. The phytoavailable Cr fraction in the soils per se was about 10-25%. In spite of the mobilization of Cr by acidic soil, the phytoavailable Cr concentration decreased to about half when the lignite particle size was either 0.5-1.0 or 1.0-2.0 mm. Lignite was suitable for Cr stabilization in acidic soil in a close particle size range, ensuring the dispersibility needed to enhance efficient Cr transfer from the contaminated soil to the stabilizer.

Fit-for-purpose soil leaching tests for stabilization of Cr(III) in soil by lignite addition.  90% and 60% of Cr(III) were immobilized in calcareous and acidic soil per se, respectively.  Calcareous soil immobilizes Cr rendering it unavailable for stabilization by lignite.  Lignite stabilizes Cr, being mobilized in acidic soil.  Cr(III) stabilization in acidic soil efficient by lignite of close particle size range.

“…However, these authors emphasised that sensitivity to Cd, Zn, Pb, and Cu may be affected by the content of SOM and granulometric composition of the soil. The above information clearly shows that excessive contents of Cd, Cu, Zn, Pb may interfere with soil homeostasis and disturb the mechanisms responsible for proper biochemical changes at the cellular level [1,6,[50][51][52][53].…”

Biochar improves soil physical, chemical and biological properties. However, there is a very limited number of studies comparing the effect of various doses of biochar and wheat straw with nutrients on microbiocenotic composition of soil and their connection with selected biochemical and chemical parameters of soil. The aim of this study was to determine the effect of the addition to the soil of wheat straw (WS) and wheat straw biochar (WSB) (300 °C) at 0.2%, 0.5%, 1%, and 2% doses and the addition of nutrients (MF) on microbial community composition (bacteria, fungi, actinobacteria, Azotobacter spp., ammonifiers, nitrifiers, denitrifiers, C. pasteurianum), dehydrogenase activity index, carbon and nitrogen fractions contents and the content of water soluble Cu, Cd, Zn, and Pb. It was demonstrated that coapplication of WS and WSB with MF at 1% and 2% doses increased carbon and nitrogen contents in soil and, in particular, their water soluble fractions (DOC and DON). The synergistic effect of biochar and MF contributed to the increase in the population of soil microorganisms. Dehydrogenase activity index in treatments with the addition of WS, WSB and MF was 1.6-4 times higher compared to the control. The content of heavy metals significantly (p ≤ 0.05) affected dehydrogenase activity and the number of nitrifiers and ammonifiers. It was demonstrated that the content of C and N measured for soil microbial biomass in treatments amended with biochar and MF was much greater than in control treatment and MF. However, our studies suggest that the microorganisms' response to the addition of biochar with nutrients increased the number and intensified the activity of soil microorganisms.
