Lead pollution in rice fields in Rancaekek is attributed to the inadequate processing of waste from the textile industry. This phenomenon engenders a decline in soil fertility, thereby posing a threat to both food quality and agricultural sustainability. Employing N Bio-Organomineral fertilizer stands as one of the measures aimed at ameliorating the quality of rice fields afflicted by heavy metal contamination, particularly lead (Pb). This study seeks to elucidate the impact of N Bio-Organomineral fertilizer on various soil parameters, namely pH, NO3 - , soil organic carbon (C-organic), soil Pb solubility, and plant Pb uptake. The research was conducted in Linggar Village, Rancaekek, spanning from December 2019 to April 2020. Utilizing a Randomized Block Design as the experimental setup consisted of eight treatments with four replications, including: a control (0), urea at 250 kg/ha, and varying doses of the fertilizer at 250, 500, 750, 1000, 1250, and 1500 kg/ha. N Bio-Organomineral fertilizer represents a modified form of nitrogen fertilizer comprising urea, zeolite, activated charcoal, and compost enriched with Bacillus subtilis, formulated in a ratio of 60:20:10:10, respectively. The findings indicate that the application of N Bio-Organomineral fertilizer leads to an augmentation in soil NO3 - and C-organic content, while concurrently mitigating the uptake of Pb by plants. Among the treatments, the application of 500 kg/ha of N Bio-Organomineral fertilizer emerges as the most efficacious in enhancing soil NO3 - and C-organic content, as well as diminishing Pb accumulation in plants
