Heavy metals (HMs) toxicity represents a global problem depending on the soil environment’s geochemical forms. Biochar addition safely reduces HMs mobile forms, thus, reducing their toxicity to plants. While several studies have shown that biochar could significantly stabilize HMs in contaminated soils, the study of the relationship of soil properties to potential mechanisms still needs further clarification; hence the importance of assessing a naturally contaminated soil amended, in this case with Paulownia biochar (PB) and Bamboo biochar (BB) to fractionate Pb, Cd, Zn, and Cu using short sequential fractionation plans. The relationship of soil pH and organic matter and its effect on the redistribution of these metals were estimated. The results indicated that the acid-soluble metals decreased while the fraction bound to organic matter increased compared to untreated pots. The increase in the organic matter metal-bound was mostly at the expense of the decrease in the acid extractable and Fe/Mn bound ones. The highest application of PB increased the organically bound fraction of Pb, Cd, Zn, and Cu (62, 61, 34, and 61%, respectively), while the BB increased them (61, 49, 42, and 22%, respectively) over the control. Meanwhile, Fe/Mn oxides bound represents the large portion associated with zinc and copper. Concerning soil organic matter (SOM) and soil pH, as potential tools to reduce the risk of the target metals, a significant positive correlation was observed with acid-soluble extractable metal, while a negative correlation was obtained with organic matter-bound metal. The principal component analysis (PCA) shows that the total variance represents 89.7% for the TCPL-extractable and HMs forms and their relation to pH and SOM, which confirms the positive effect of the pH and SOM under PB and BB treatments on reducing the risk of the studied metals. The mobility and bioavailability of these metals and their geochemical forms widely varied according to pH, soil organic matter, biochar types, and application rates. As an environmentally friendly and economical material, biochar emphasizes its importance as a tool that makes the soil more suitable for safe cultivation in the short term and its long-term sustainability. This study proves that it reduces the mobility of HMs, their environmental risks and contributes to food safety. It also confirms that performing more controlled experiments, such as a pot, is a disciplined and effective way to assess the suitability of different types of biochar as soil modifications to restore HMs contaminated soil via controlling the mobilization of these minerals.

“…Besides, understanding rice response to lime application in acid paddy soils is of great importance for attaining yield potential to meet the dynamic of population development. It has been widely reported that lime application in acid soils greatly improves crop productivity directly through enhancing soil physical, chemical, and biological properties, which ultimately increase the availability and mobility of plant essential nutrients (Chan and Heenan 1998;Bolan et al 2003;Jaskulska et al 2014;Al-Sayed et al 2020;Rekaby et al 2020). Besides, the increase in rice grain yield in acid soils in response to liming was mainly ascribed to the increase in soil pH which drastically decreases aluminum toxicity and promoted the absorption of Ca, Mg, P, and K (Rahman et al 2005;Goswami et al 2008;Previna and Baskar 2012;Fageria and Nascente 2014;Crusciol et al 2016;Zeng et al 2017).…”

Lime application is the most effective agricultural practice for the reduction of cadmium (Cd) bioavailability in acid soils. This study was conducted to investigate the impact of continuous liming across five consecutive growing seasons on the remediation of Cd in acid paddy soils, as well as rice yield. Two rice cultivars, i.e., Zhuliangyou 819 and Xiangwanxian 12, were cultivated in Cd-contaminated paddy soil for five consecutive growing seasons from 2014 to 2018. The investigated lime levels were 0, 450, 900, 1350, 1800, 2250, 3000, and 3750 kg ha −1. Lime application significantly increased rice yield, soil pH, exchangeable soil Ca 2+ , and rice calcium (Ca) contents; besides, it reduced soil and rice Cd contents. The application of lime at the rate of 1350-2250 kg ha −1 significantly increased rice yield. Under continuous liming, rice yield obviously increased first and then decreased with the cumulative application of lime. The application of a cumulative lime amount of 18,000 kg ha −1 was identified as the critical transition point of soil pH, soil Cd, and rice Cd content. Application of lime up to or above 3000 kg ha −1 per season reduced Cd content in brown rice below 0.20 mg kg −1. The results suggest that the reduction in effective Cd content might be a result of the combined action of exchangeable soil Ca 2+ and soil pH rather than being a direct effect of Ca 2+. Therefore, acid Cdcontaminated paddy fields can realize the safe production of rice by the continuous application of an appropriate amount of lime.

“…Malik and Chauhan [30] reported the higher values for soil N, P & K contents due to integrated use of organic and inorganic source of nutrients. Rekaby, et al [31] observed higher availability of nutrients in Egypt soils after organic amendment (biochar, humic acid, compost). As noted by Demir and Gulser [32], application of rice husk compost improved the N, P & K status of soil.…”

Composting of municipal solid waste (MSW) is a good option for solid waste recycling, but its use by the farmers is limited because of its very low nutrient status. Aims: The study aimed at nutrient enrichment of marketed MSW compost by using some organic materials and evaluating the influence of nutrient enriched MSW compost on yield and nutrient content of cabbage (Brassica oleracea L.). Place and Duration of Study: MSW compost amendment, field experiment and nutrient analysis were carried out at Bangladesh Agricultural University (BAU), Mymensingh during October 2017 to June 2018. Methodology: We prepared three types of amended compost by mixing 20% mustard oil cake (MOC), and 30% poultry manure (PM) or cow dung (CD) or sugarcane press mud (SPM) with 50% MSW compost. A liquid culture of Trichoderma viride was inoculated to every type of compost. The field experiment was conducted to evaluate the performance of the amended MSW composts on yield and nutrient content of cabbage (cv. Atlas-70), and on soil fertility. The experimental soil was silt loam having 6.7 pH and 2.79% organic matter; according to Soil Taxonomy it belongs to Aeric Haplaquept under the order Inceptisols. Results: Based on the yield and nutrient concentration (N, P, K & S) of cabbage, the treatment containing 50% fertilizers + 50% compost mixture (MSW compost + MOC + SPM in a ratio of 5:2:3) demonstrated the best result followed by poultry manure amended compost. Use of the amended composts had residual effects on soil showing an increased N, P, K & S content. Conclusion: Organic amendment of MSW compost inoculated with Trichoderma is a noble means to increase the nutrient status of marketed MSW compost and improve the soil fertility and crop productivity. The results have significant value in fertilizer management strategies for vegetables cultivation in sub-tropical countries.
