“…In the Cd adsorption test using the batch method, the maximum adsorption amount of Cd to FBWA showed higher or comparable levels than those of the other amendments obtained from organic wastes in recent reports (Table S6 in the SI) 30, [39][40][41][42][43][44][45] .…”

We monitored the relationship between cadmium (Cd) concentration uptake of rice and oxidationreduction potential (ORP) at the soil surface with supplementation of fermented botanical wastebased amendment (FBWA), an organic fertilizer prepared from woody and food wastes. This study was carried out for 3 years in the western part of Jiangsu Province, China. It was found that the Cd concentration taken up by rice was correlated to a decreased ORP of the cultivated soil. The yield of rice was ~1.20 times higher than that of the control plot. The effects of reducing Cd content in rice and increasing rice yield remained for 2 years after FBWA application. Finally, Cd in the soil was immobilized by adsorption to FBWA or the decomposed products. The ORP measurement during rice cultivation might be a key index to predict the suppression effect of Cd uptake into the rice or limitation of the sustainable effect by the FBWA.

“…Similar trends have been reported previously. [ 39,40 ] For example, the addition of straw‐based biochar amendment to red soil moved the ζ potential of the soil colloid into the negative direction, reducing the positive charge on the soil surface and increasing its negative charge. [ 39,40 ] The differences in the ζ potentials of the soil in the controls of the different cultivars could be ascribed to the organic acid from the roots of the leafy vegetables.…”

[ 39,40 ] The differences in the ζ potentials of the soil in the controls of the different cultivars could be ascribed to the organic acid from the roots of the leafy vegetables. The reduced ζ potential qualitatively indicates that it is beneficial for the adsorption and fixation of metal cations on the surface of the soil colloid, [ 38 ] but due to the adsorption affinity of each cation and the difference in their chemical forms, the degree of adsorption enhancement needs to be determined separately in conjunction with the equilibrium adsorption experiment.…”

Cd pollution in agricultural soil and its subsequent accumulation in crops are a global concern. In situ immobilization is an efficient remediation method; however, there are only few reported amendments for neutral soil. In this study, thiolated palygorskite (TPAL) is employed as a potential amendment. To comprehensively investigate the remediation effects and associated mechanisms of TPAL, a pot‐scale cultivation experiment with pakchoi and romaine lettuce is conducted. TPAL reduces the available Cd concentrations in the soil by 38.12–57.54% at doses of 0.1–0.3% and subsequently decreases Cd accumulation in the leafy vegetables. TPAL clearly decreases the ζ potentials of the amended soil and increases their maximum sorption capacity to promote Cd fixation in the soil. Correlation and principal component analyses confirm that the immobilization effect is correlated with the maximum sorption capacity of the soil for Cd2+. Furthermore, TPAL reduces the biological concentration factors to inhibit the transfer of Cd from the soil to the roots of the vegetables. TPAL increases the vegetable biomass and has no elevating effects on the soil pH or available concentrations of trace elements in the soil, illustrating its environmental friendliness. Overall, TPAL is a good immobilization amendment for Cd‐contaminated neutral soils.

“…After the crop harvest, soil samples were taken from each unit and measured soil pH and EC using pH and EC meter according to the described method in our previous study 8 . Bioavailable Cd contents from each potted soil were estimated using the CaCl 2 extractable technique 6,7 . Soil organic matter contents were calculated by using the wet oxidation method 28 .…”

Wastewater irrigation to the farmlands has become a serious environmental threats because of food chain deterioration 6 . Cd is highly reactive and mobile, which has the potential to in uence the plants growth.…”

Cadmium contamination in croplands is recognized as one of the major threats, seriously affecting soil health and sustainable agriculture around the globe. Cd mobility in wastewater irrigated soils can be curtailed through eco-friendly and cost effective organic soil amendments compost (CP), press mud (PM) and moringa leaf extract (ME) at 3% rate that eventually reduces its translocation from polluted soil to plant. This study explored the possible effects of various types of organic soil amendments on cadmium (Cd) phytoavailability in wastewater degraded soil and its subsequent accumulation in maize tissues. Maize plant was grown in Ghazi University as a test plant and Cd accumulation was recorded in its tissues, translocation from root to shoot, chlorophyll contents, plant biomass, yield and soil properties (pH, NPK, OM and Soluble Cd) were also examined. Results revealed that the addition of amendments significantly minimized Cd mobility in soil by 45.8%, 23% and 19.4% when CP, PM and ME were added at 3% over control. Comparing the control soil, Cd uptake effectively reduced via plants shoots by 33.3%, 27.7% and 19.4% when CP, PM and ME. In addition, NPK were significantly increased among all the added treatments in the soil-plant system as well as improved chlorophyll contents relative to non-treated soil. The Current study suggested that among all the amendments, compost at 3% rate performed well and might be considered a suitable approach for maize growth in polluted soil.
