“…However, the results found here emphasized the fact that biochar and redmud effects are highly dependent on the biochar/redmud type as only hardwood biochar and neutralized redmud had beneficial effects. Previous studies observed positive outcomes with the use of redmud or biochar (Castaldi et al, 2009;Rafael et al, 2019;Sabir et al, 2013). Negative effects were also observed.…”

“…Such soil acidity was also observed in the fertilized condition and could also explain why it did not improve plant growth, although it increased nutrient content. The amelioration of plant growth with Bc1 and RM2 can be explained by an increase in soil pH, which reduced metal(loid) bioavailability and mobility (Castaldi et al, 2009;Rafael et al, 2019), as shown by the soil pore waters and CaCl 2 extractions. Moreover, other ameliorations of the soil conditions could have also contributed, such as increases in cation exchange capacity and an alteration of the microbial community and activity (Hmid, Al Chami, Sillen, De Vocht, & Vangronsveld, 2015;Rafael et al, 2019).…”

Effects of carbon‐based materials and redmuds on metal(loid) immobilization and growth of Salix dasyclados Wimm. on a former mine Technosol contaminated by arsenic and lead

Metal(loid) soil contamination is a widespread issue and its remediation a priority.Phytoremediation involves the use of plants to stabilize/extract metal(loid)s and prevent spreading of contaminants. Salicaceae are fast growing trees that can tolerate and accumulate metal(loid)s. Amendments may be needed to facilitate plant growth on the contaminated substrate. Biochar, the solid product of pyrolysis, can ameliorate soil properties and reduce metal(loid) bioavailability but showed low affinity toward arsenic. Redmud, a waste product, can immobilize arsenic and other metal(loid)s and improve soil conditions. To evaluate the potential of those amendments to immobilize metal(loid)s and facilitate the establishment of a cover vegetation with willow (Salix dasyclados Wimm.), a pot experiment was conducted using several carbonbased materials (biochar and activated carbon) and redmuds. Two carbon-based materials and two redmuds were selected for the pot experiment based on characteristics and sorption tests. A former mining soil was amended with these products and Salix dasyclados cuttings were planted. Biochar and one redmud improved growth of Salix dasyclados Wimm. Redmud, which is cheaper than biochar, performed equally well as the biochar at a lower application rate. It can therefore be concluded that the application of redmud, associated to Salix dasyclados, could be an option for the phytoremediation of an As and Pb contaminated soil. However, these results need to be evaluated on a bigger scale to assess the gain brought by the combination of redmud and Salix dasyclados on the contaminated area.

“…Functional groups such as -COO − and O − in the surface of biochar can react with H + in soil to improve the buffering capacity of soil (Wu et al 2020b). Additionally, the chemical properties and enzymatic activities of the soil are significantly improved after biochar amendment (Pokharel et al 2020;Rafael et al 2019). Biochar can also reduce the bioavailability and toxicity of soil by adsorbing and degrading organic contaminants (Wu et al 2020a).…”

In view of the risks induced by the inhibitory effects of applying impracticably large amounts of sewage sludge biochar (SSB) to the alkaline soil, this field study investigated the influence of moderate biochar amendments (0, 1500, 4500, and 9000 kg/hm2) on corn growth, alkaline soil properties, and the uptake of potentially toxic elements (PTEs). The results showed that applying more SSB would decrease the ammonium nitrogen concentration and increase the available phosphorus and potassium concentrations, which inhibited corn plant growth because of high background nutrient levels of the alkaline soil. When the alkaline soil was amended with 1500 kg/hm2 SSB, the dry weight of 100 niblets increased from 32.11 g in the control to 35.07 g. There was no significant variation in the total concentration of PTEs in the soil. The concentrations of Mn, Ni, Cu, and Zn in niblets decreased from 5.54, 0.83, 2.26, and 27.15 mg/kg in the control to 4.47, 0.62, 1.30, and 23.45 mg/kg, respectively. Accordingly, the health risk from corn consumption was significantly reduced. Furthermore, the combination of SSB and fertilizer improved corn growth and reduced the risk of consumption of PTEs. Therefore, considering the increase in corn fruit yield and the decrease in consumption risk, applying 1500 kg/hm2 of biochar to alkaline soils is a realistically achievable rate, which can broaden the utilization of SSB for remediation of different types of soil.

The leading branch of agriculture in Tatarstan is animal husbandry. In animal husbandry, the main direction is the production of milk and cattle meat. In the diet of dairy cows, corn is an integral component. The share of fodder corn in the total cultivated areas is on average 30-35 %. A limiting factor in the cultivation of corn is the lack of macronutrients in the soil. To obtain stable high yields of green mass of corn, it is necessary to choose the right combination of NPK, based on soil indicators. In this regard, it is necessary to improve the mineral nutrition systems of highly productive adaptive maize hybrids. The effect of fertilizers on leaf surface growth and photosynthetic potential in maize crops was studied in the field on gray forest soils of the Volga region of the Republic of Tatarstan. A significant increase in the yield of green mass was found due to the increased level of mineral nutrition of plants. The fertilizer provided an increase in leaf area by 2.6-9.82 thousand m 2 /ha on the option N60P54K168 and 4.85-14.56 thousand m 2 /ha in N180P154K294. The maximum value of this indicator was obtained from the Newton hybrid for the interphase period of flowering-milk ripeness on fertilized variants was between 9.79 and 10.23 thousand m 2 /ha, against 7.07 thousand m 2 /ha on the control variant. The photosynthetic potential was the highest hybrids (1924.91 and 1956.91 thousand m 2 x day/ha for the option of N60P54K168 and 2039.84 and 2066.31 thousand m 2 x day/ha for the N180P154K294). Consequently, the planned yields of green mass were obtained on crops of hybrids 9 and 43.9 t/ha with the introduction of calculated doses of mineral fertilizers at 50 t/ha and 62.6 and 65.3 t/ha against the background of mineral fertilizers at 70 t/ha. Based on the calculations of economic efficiency, it follows that the cultivation of the Newton hybrid against the background of making NPK at the highest cost (28151.5 RUB/ha) and the lowest cost of 1 ton of green mass of corn (431.1 RUB) provides a greater net income (11028.5 RUB/ha) with the best level of profitability (39.2 %).
