Mitigation of Cadmium Stress in Lettuce (Lactuca sativa L.) Using Rice Husk Biochar and Silica Fertilizer
Heavy metal contamination, particularly cadmium (Cd), can arise from the use of organic fertilizers derived from urban waste. Cd is highly toxic and mobile, posing serious health risks when accumulated in edible crops such as lettuce. This study aimed to evaluate the potential of rice husk biochar (RHB) and silica fert...
