“…A similar response was observed in wheat grains grown in calcareous soils [54]. This increased protein content of quinoa seed could be explained by the role of organic amendments for overall improvement in soil health and delivery of essential nutrients to plants [55]. In addition, reduction in salt toxicity to plants through the adsorption of Na + on large B surface areas in the soil might be another possible mechanism for the increase in protein content of quinoa seeds [22,56].…”

The objective of this study was to evaluate the individual and synergic effects of the application of Biochar (B), Humic Substances (HS), and Gypsum (G) on the soil properties of a saline–sodic soil, and plant growth and seed quality (polyphenols, protein and yield) of quinoa. Treatments included (B) 22 t ha−1, (HS) 5 kg ha−1, and (G) 47.7 t ha−1. Two quinoa genotypes from Arid Zones (AZ-51 and AZ-103) were selected and established in eight treatments. The B + HS + G combined treatment resulted in increases in root biomass of 206% and 176% in AZ-51 and AZ-103, respectively. Furthermore, electrical conductivity (ECe), sodium adsorption ratio (SAR), and exchangeable sodium percentage (ESP) decreased significantly in all treated soils. When compared to the control, ESP decreased 11-fold in the G treatment, and 9–13-fold in the B + G; B + HS; and B + HS + G treatments. Similarly, soil microbial biomass increased 112% and 322% in the B + HS + G treatment in AZ-51 and AZ-103 genotypes, respectively. Therefore, it can be concluded that the application of combined amendments (B + HS + G) represents an alternative for reclaiming degraded soils, including saline–sodic soils.

“…Likewise, the application of BN in Pb-polluted soil significantly improved shoot DW and Chl contents in Chinese cabbage [7]. Improvement in the plant DW, RWC and Chl contents could be attributed to the various characteristics of BR like provision of essential nutrients, improvement in WHC and alteration in redox condition of the soil [23][24][25]. Likewise, improvement in the agronomic and biophysical parameters of plants is also due to the alleviation of Pb toxicity to them after the Pb has been immobilized onto the BR surface [3,12,13].…”

Lead (Pb)-polluted soils pose a serious threat to human health, particularly by transmitting this heavy metal to the food chain via the crops grown on them. The application of novel amendments in Pb-polluted soils can significantly reduce this problem. In this research, we report the effects of various organic and inorganic amendments i.e., bentonite (BN), biochar (BR), lignin (LN), magnesium potassium phosphate cement (CM) and iron hydroxyl phosphate (FeHP), on the Pb bioavailability in Pb-polluted soil, upon Pb distribution in shoots, roots, grain, the translocation factor (TF) and the bioconcentration factor (BCF) of Pb in pea (Pisum sativum L.) grain. Furthermore, effects of the said amendments on the plant parameters, as well as grain biochemistry and nutritional quality, were also assessed. Lead pollution significantly elevated Pb concentrations in roots, shoots and grain, as well as the grain TF and BCF of Pb, while reducing the nutritional quality and biochemistry of grain, plant height, relative water content (RWC), chlorophyll contents (chl a and chl b) and the dry weight (DW) of shoot, root and grain. The lowest Pb distribution in shoots, roots and grain were found with BN, FeHP and CM, compared to our control. Likewise, the BN, FeHP and CM significantly lowered the TF and BCF values of Pb in the order FeHP > CM > BN. Similarly, the highest increase in plant height, shoot, root and grain DW, RWC, chl a and chl b contents, grain biochemistry and the micronutrient concentrations, were recorded with BR amendment. Biochar also reduced grain polyphenols as well as plant oxidative stress. Given that the BR and BN amendments gave the best results, we propose to explore their potential synergistic effect to reduce Pb toxicity by using them together in future research.

“…Consequently, BI (Shaaban et al, 2018a;Zhai et al, 2018) and calcite (Lombi et al, 2003;Mallampati et al, 2012;Huang et al, 2016) are considered as the efficient and common immobilizing agents for acid soil restoration. It has been reported that the incorporation of BI and calcite to Ni contaminated soil improves soil health, minimizes the PTE accumulation in plants, and thereby improves their dry biomass (Lee et al, 2009;Cui et al, 2016b;Shahbaz et al, 2018). Furthermore, Huang et al (2016) reported that calcite can be used to remediate PTEs' polluted soils as it has large surface area porous structure, which may contribute to increase Ni immobilization in the soil through adsorption and surface complexation (Hung et al, 2016;Lahori et al, 2017).…”

In agricultural field, nickel (Ni) contamination has become a serious concern/threat all over the world due to its hazardous effects on ecosystem and food chain. An incubation study was conducted to investigate the simultaneous efficiency of rice straw (RS) and its derived biochar (BI), calcium carbonate (calcite), zeolite (ZE), and triple superphosphate (TSP) on the stabilization of Ni in contaminated soil. Various chemical extraction techniques, including the sequential extraction (BCR), leaching toxicity (TCLP) test, and single CaCl 2 extraction, were performed. The results revealed that greater reduction in acid-soluble fractions of Ni was observed by 45%, 65.1%, 42.1%, 55.7%, and 33.9% with RS, BI, ZE, calcite at 2%, and TSP 0.5% application rate, respectively. Similarly, TCLP and CaCl 2-extractable Ni were significantly decreased by 49.8% and 97.5% with 2% BI application rate, respectively. The soil pH, EC, and organic matter were significantly improved with the incorporation of RS, BI, ZE, TSP, and calcite amendments. Overall, among all the amendments, the incorporation of BI and calcite was considered to be the best option for Ni immobilization and thereby reducing its mobility in Ni contaminated soil. These findings suggest that RS biochar and calcite can be used as Ni stabilizers in contaminated agricultural soils.
