Comparative efficacy of biochar vs. cooking charcoal in urea-based soil fertility management: Impacts on soil quality, nutrient Retention, and maize performance

Published: Oct. 17, 2024

Biochar stands out for its valuable properties in promoting sustainable agricultural practices. However, Nigerian farmers face significant challenges adopting biochar due to the high costs associated with acquiring pyrolizers or fabricating local kilns. They are, however, familiar charcoal production domestic use. This screen house trial was a factorial combination of three black carbon types: biochar, charcoal, and no (NBC) each applied at 5 t/ha urea levels: 0, 30 60 kg N/ha). Maize grown on amended soils six weeks. The Fourier Transform Infrared scans revealed differences between two carbons, showing sharper peaks wavelengths 1588, 1375, 1100 nm. Soils significantly outperformed those treated carbon, higher levels soil organic (7.05 g/kg compared 5.12 4.09 NBC, respectively), available phosphorus (135.57 mg/kg 4.12 5.48 exchangeable bases, maize nitrogen uptake, total dry biomass yield. Paired T-tests impact nutrient conditions, ultimately affecting performance. Therefore, cooking cannot substitute when environmental benefits are desired.

Biochar stands out for its valuable characteristics in enhancing soil properties but the high cost of pyrolizers large scale biochar production has hindered local farmers from enjoying these benefits leading to suggestion achieving similar readily available cooking charcoal. Thus, need compare reactions two black carbons soil. Three carbon types: biochar, charcoal, and no (NBC) applied at 5 t/ha three urea levels: 0, 30 60 kg N/ha were combined factorially a screen house trial. Maize was grown on amended soils six weeks. The Fourier Transform Infrared scans revealed differences between carbons, with showing sharper peaks wavelengths 1588, 1375, 1100 nm. supported significantly (p < 0.05) highest organic (7.05 g/kg), phosphorus (135.57 mg/kg) as well exchangeable bases, maize nitrogen uptake, total dry biomass yield. Paired T-tests significant impact charcoal carbon, nutrient conditions, performance. Therefore, cannot substitute when environmental associated are desired. Long term repetition work under field condition is suggested further validate findings.
