The return of livestock and poultry manure (LPM) to fields is necessary for sustainable agricultural development, but it also a primary source heavy metal contamination in land, which potentially threatens soil crops. Conflicting results have been reported previous studies on the impacts returning LPM cadmium (Cd) accumulation Herein, we investigated applying such Cd crops through meta-analysis. We explored relationships content with properties, experimental conditions, properties. Moreover, evaluated reasons differences different factors influencing them. Upon LPM, contents total Cd, available crop grain increased by 30.96%, 86.91%, 20.43%, respectively, root decreased 16.91%. Random forest analysis decision tree further quantified importance each factor identified contents. From perspective safe production, some suggestions were made fields: (1) higher pH or increasing dosage soils low <5.7; (2) <1.8 mg/kg, >5.7, organic matter >19 g/kg, was associated risk grains; (3) while planting low-Cd-accumulating varieties. This study provides scientific guidance use resources helps reduce accumulation.

The synergistic application of calcium (Ca) and magnesium (Mg) was investigated to mitigate cadmium (Cd) uptake translocation in rice grown Cd-contaminated soil. A pot experiment conducted using different Ca:Mg molar ratios (Ca1:Mg2, Ca2:Mg1, Ca1:Mg1) evaluate their effect on Cd uptake. results showed that the Ca1:Mg1 treatment achieved highest reduction grain content (54.7%, p < 0.05), followed by Ca2:Mg1 (47.6%), Ca1:Mg2 (40.7%), all below China's National Food Safety Standard (0.2 mg kg−1).

Abstract Agricultural soil contamination by cadmium (Cd) is a globally recognized concern, with biochar presenting considerable potential for remediation. However, the response of various crop components to application Cd pollution mitigation remains insufficiently understood. A literature review covering publications from 2017 2023 compiled 364 datasets 60 studies evaluate responses different parts three crops treatment in Cd‐contaminated soil. Findings indicated that reduced bioavailability 30.5% and decreased accumulation roots, shoots, leaves grains 31.3%, 34.0%, 25.3% 43.1%, respectively, most pronounced reduction observed grains. The efficiency remediation influenced its characteristics rates. Composite biochar, synthesized through co‐pyrolysis biomass other materials, demonstrated highest effectiveness reducing concentrations crops. Pyrolysis conducted at 400–600°C 2–4 h significantly enhanced biochar's potential, while pH range 6.5–8.5 rates above 2% notably absorption These results contribute valuable insights into applicability materials agricultural soil–crop systems, offering guidance on their anticipated mitigating contamination.

Traditional enhanced modern tools, enables the development high-yielding, low-Cd cultivars but time-consuming. Genome particularly CRISPR-Cas9, offers precise gene modifications faces regulatory constraints. Digital mapping provide high-resolution maps targeted interventions require extensive calibration. Silicon supplementation promising approach, as it competes sites, translocation edible plant parts. Additionally, Si enhances tolerance abiotic stresses, making multifunctional solution. Selenium can also while offering benefits.
