“…This might be resulted from the increase in soil pH and organic matter after incorporation of active carbon in the Cd/Pb polluted soil. Mohamed et al (2015) indicated that the increase in pH after application of organic residues in heavy metal-polluted soils was considered as one of the most important factors in controlling both Cd immobilization and mobility in these soils by several ways, including adsorption of metals on active sites of organic materials or precipitation of metals in less mobile forms (oxides, hydroxides and carbonates). It was also reported by Shaheen and Rinklebe (2015) that organic matter had high ability to reduce both availability and mobility of heavy metals in the soils due to their redistribution from the soluble/exchangeable forms to other geochemical fractions bounded with carbonates, Fe/Mn oxides and organic matter.…”

A field experiment was conducted to investigate the effect of chicken manure compost on the fractionation of cadmium (Cd), soil biological properties and Cd uptake by wheat in a soil affected by mining activities in Hubei province, China. Compost was applied at five levels (0, 27, 54, 108, 216 t ha(-1)), and winter wheat (Triticum aestivum L.) was chosen as an indicator plant. Results showed that the application of compost increased soil pH and the content of total phosphorus and organic matter. Soil biological properties such as microbial biomass carbon, invertase, protease, urease and catalase activities were significantly enhanced by 0.24-3.47 times after compost application. Sequential extraction indicated that compost amendments decreased the acid-extractable Cd by 8.2-37.6 %, while increased the reducible and oxidisable Cd by 9.2-39.5 and 8.2-60.4 %, respectively. The addition of 27-54 t ha(-1) compost reduced Cd content in wheat stems and seeds by 69.6-75.0 % and 10.3-18.4 %, respectively. However, only 25.5-26.5 % reductions in Cd content in wheat stems were observed in 108-216 t ha(-1) compost amendments, and no significant decrease was detected for seeds. This study suggests that although compost is a suitable organic amendment to improve soil fertility and biological activities, the addition of compost should be moderated by an appropriate rate to optimize the use of compost for the reclamation of metal-contaminated soils at field scale.

“…Dry weights of straw, seeds, and roots of faba bean plants were determined after harvest. Contents of NPK and microelements (Fe, Mn, Mo, and Zn) of seeds were determined after their digestion using a mixture of H 2 SO 4 and HClO 4 (2 : 1, ) as mentioned in Mohamed et al (). Total crude protein percentage (%) was calculated by multiplying N concentrations by 6.25, while total carbohydrates were determined colorimetrically using the method of A.O.A.C .…”

Leguminous crops are significantly involved in the global symbiotic biological N2 Fixation (BNF), an eco‐friendly process in the agriculture system. Biochar is considered as a vital amendment in improving growth and quality of crops and soils. Few investigations have been conducted to determine the combination effect of biochar with microelements on growth of legumes and soil properties. This study was designed to study the effect of soybean straw‐derived biochar (SSDB) with or without microelements on soil microbial and chemical properties, growth, yield, and seed chemical composition of faba bean (Vicia faba L.). Results revealed that dehydrogenase (DHA) and phosphatase (P‐ase) activities were markedly improved with the increase of SSDB rates under addition of microelements and their highest values were recorded after 90 d. Significant increases were noticed in nodulation activities, nodulation numbers (30.1–72.8), concentrations of N (1.62–1.93%), P (0.15–0.21%), and K (0.53–0.67%), and seed chemical constituents due to the addition of SSDB in the presence of microelements. Moreover, the combination of biochar with microelements caused significant changes in microbial counts. Overall, this investigation shows the potential and role of SSDB in enhancing the growth quality of faba bean seeds as well as an improvement of soil characteristics.

“…Biochar as a soil amendment is used to improve soil quality over both the long and short term (Khaledian et al, 2013;Krause et al, 2016). Its reported benefits have included mitigation of nitrous oxide (N 2 O) emissions (Hüppi et al, 2015;Harter et al, 2016), improved nutrient availability (Drake et al, 2016;Olmo et al, 2016;Pandey et al, 2016), prevention of heavy metal pollution (Bian et al, 2013;Mohamed et al, 2015), general control of environmental pollution (Fernández-Calviño et al, 2016), and storage of organic carbon. Interest in biochar and its potential environmental applications, including heavy metal remediation, has increased interest in investigating the relationships between soil organic carbon and metal content.…”

Industrial activities can contribute to the accumulation of heavy metals in soils, which could potentially threaten public health and the environment. This research was conducted to investigate the relationships between pH and total organic carbon (TOC) with soil chemical parameters, including exchangeable and total Cu, Zn, Cd, Pb, K, and Mg concentrations in soils near Panevėžys and Kaunas, Lithuania. Principal component regression (PCR) and non‐linear regression were used to find statistical relationships between pH, TOC, and the other soil properties studied. The results of correlation tests indicated that pH and TOC had strong relationships with most of the soil properties. The results of PCR [R2 = 0·87, RMSE = 0·046] and non‐linear regression [R2 = 0·91, RMSE = 0·041] (pH and the entire parameters), PCR [R2 = 0·777, RMSE = 0·058] and non‐linear regression [R2 = 0·871, RMSE = 0·046] (pH and the exchangeable parameters) to model the relationships between pH and soil chemical properties were promising and significant. Exchangeable heavy metal concentrations increased for pH > 5. Even though the relationships between TOC and heavy metals were significant, they were not as powerful as the relationships between pH and these metals. It was concluded that total metal concentrations in the study soils can be predicted by either pH or TOC. Metal mobility could most likely be controlled at the study site by manipulating soil pH and/or TOC. Finally, it is suggested that when there are financial and time limitations, assessment of total exchangeable metal concentrations using soil pH and/or TOC could be productive.
