Abstract

Peri-urban agriculture is becoming a potential step to promote sustainable and environmental food production systems. Our aim was to study the effect of biochar application at various rates on faba bean growth, cellulose decomposition, nodulation, and selected enzyme activities associated with carbon cycling in clay and sandy soils collected from peri-urban agricultural areas near the city of El-Minia, Egypt. To achieve this aim, incubation and pot experiments were conducted under controlled greenhouse conditions using clay and sandy soil. Among the studied treatments, using biochar at the rate of 3 kg/sq·m was the most effective soil amendment followed by biochar at the rate of 2 kg/sq·m. At 60 days of incubation, the count of cellulose-decomposing microorganisms reached a high level in both clay and sandy soil, and then decreased after 90 days, regardless of the biochar rate. The response of the cellulose-decomposer ratio (Fcd/Bcd) was positively correlated with biochar rates and incubation time. The obtained results showed significant increases in fresh and dry weight in clay soil compared to sandy soil. In any case, the use of biochar as a soil amendment enhanced soil health, soil microbial communities, and increased cellulose-decomposing microorganisms, thus improving faba bean nodulation and growth.
