Amelioration of lead (Pb) stress in Brassica campestris L. by synergistic application of biochar and compost under Pb-contaminated soil.
Lead (Pb) is one of the most toxic heavy metals adversely affecting agricultural productivity, soil health, and food safety. Organic amendments (OAs), particularly biochar (BC) and compost (C), can mitigate heavy metal toxicity through Pb (II) immobilization, improved soil physicochemical properties, enhanced nutrient...
