Analysis of biochar and digestate as biofertilizers in lettuce cultivation

Compared to conventional chemical fertilizers, biofertilizers derived from biodegradable waste reduce greenhouse gas emissions, recover essential nutrients, and support sustainable agriculture (Sharma et al., 2023). Biofertilizers derived from biowaste are aligned with circular economy principles and provide long-term environmental and economic benefits (Foughal et al., 2023). In this study, the effect of biochar and digestate on the growth of lettuce (Lactuca sativa) plants was explored. Biochar and digestate applied as biofertilizers in agriculture enhance soil fertility providing essential nutrients as nitrogen and phosphorus. Additionally, biochar enhances the aeration and water-retention capacity of the soil.
