“…Heavy metals in soil can affect various growth indicators in cereal plants, with the degree of impact varying depending on factors such as the metal type, concentration, exposure duration, and the cereal species involved [101][102][103][104]. Some of the key growth indicators affected by heavy metals in soil are provided in Table 3.…”

The impact of heavy metal presence in soil on cereal crops is a growing concern, posing significant challenges to global food security and environmental sustainability. Cereal crops, vital sources of nutrition, face the risk of contamination with toxic heavy metals released into the environment through human activities. This paper explores key aspects requiring thorough investigation to foster innovation and understand intricate interactions between heavy metals and cereals. Visible symptoms and physiological changes resulting from heavy metal contamination, such as chlorosis and stunted growth, demand further research to devise targeted mitigation strategies and sustainable agricultural practices. Root barrier formation, mycorrhizal symbiosis, and metal-binding proteins emerge as critical defence mechanisms for combating heavy metal stress, offering opportunities for developing metal-tolerant cereal varieties. Research on metal bioavailability and food safety implications in cereal grains is vital to safeguard human health. This paper reveals that multidisciplinary collaboration and cutting-edge technologies are essential for promoting innovation beyond the state of the art in elucidating and mitigating the impacts of heavy metals on cereal crops. Genetic and breeding approaches show promise in developing metal-tolerant cereal varieties, while agronomic practices and soil amendments can reduce metal bioavailability and toxicity. Unravelling the complex mechanisms underlying heavy metal uptake and tolerance is essential for sustainable cereal agriculture and worldwide food sustainability. Embracing the challenges of heavy metal pollution through proactive research and collaboration can secure a resilient future for cereal crops amid evolving environmental conditions.

Many years ago, widespread and ineffective technologies led to significant ecological contamination, primarily due to heavy metals (HMs), particularly lead (Pb) and cadmium (Cd). Plant growth in heavy metals contaminated and calcareous soil is a challenge for all the growers worldwide. Several organic and inorganic amendments are used by researchers in different types of soils. However, their impact on soil contaminated with toxic metals and alkaline in reaction is still unclear. Therefore, the current pot experiment investigates the relative effect of organic (wheat straw biochar and farmyard manure) at 10 and 20 t ha−1 and inorganic (diammonium phosphate and gypsum) at 100 and 150 kg ha−1 amendments on NPK availability, soil organic matter, soil properties, and maize growth under Cd and Pb stress. Highest soil pH (7.61), soil electrical conductivity (0.25 dS m−1), soil organic matter (1.40%), plant height (92 cm), shoot dry weight (41 g), and root dry weight (5.5 g) were observed because of biochar application at 20 t ha−1. While the highest total nitrogen (N) (0.13%), and phosphorus (P) (8.16 mg kg−1) were recorded with diammonium phosphate application at 150 kg ha−1, moreover, application of farmyard manure at 20 t ha−1 increased the soil potassium (K) (108.14 mg kg−1). Biochar application at 20 t ha−1 greatly reduced the toxic metals bioavailability with a high immobilization index, that is, Cd (52%) and Pb (43.79%) lead to lower concentrations of metals in roots and shoots as well. A negative correlation was identified between soil pH, soil organic matter, and soil Cd, Pb, demonstrating the positive impact of biochar in terms of the reduction of toxic metals by enhancing pH and soil organic matter, found to be the most effective amendment for soil improvement and plant growth under Cd and Pb stress condition.
