Cadmium and Agriculture: Adverse Effects on the Soil -Plant System and Remedial Strategies

As one of the most toxic heavy metals, Cadmium (Cd) significantly impacts the soil fertility and plant nutrition. This metal adversely affects plant growth and productivity by reducing the availability of essential nutrients, disrupting water and nutrient uptake, and increasing oxidative stress. Cadmium enters the soil through natural and anthropogenic sources and can transfer into the food chain, posing risks to human health. Its interactions with soil nutrients such as phosphorus, zinc, iron, and manganese influence its bioavailability and environmental behavior. Effective soil fertility and plant nutrition management strategies, including pH regulation, organic matter application, and the provision of essential nutrients, play a crucial role in mitigating cadmium toxicity. Moreover, phytoremediation is proposed as a cost-effective, efficient, and environmentally friendly approach to remediate cadmium-contaminated soils. This study reviews the detrimental effects of cadmium on soil and plants and introduces management strategies to reduce the damage caused by this heavy metal.
