Other claims from this paper (7)
- Intervention effect Bean husk biochar with Burkholderia cepacia stimulated cowpea growth.
- Intervention effect Grape fermentation residue biochar with Burkholderia cepacia promoted soil phosphatase activity.
- Intervention effect Biochar and bacterial combinations increased soil pH, phosphorus, and potassium.
- Intervention effect Biochar and bacterial combinations increased soil organic carbon content and urease activity.
- Intervention effect Biochar and bacterial combinations did not affect microbial biomass carbon or β-glucosidase activity.
- Intervention effect BRA plus GFB gave 3.85-fold higher cowpea productivity than commercial peat treatment.
- Recommendation The authors propose biochar as a sustainable carrier for plant growth-promoting bacteria and an alternative to chemical fertilizers in poor soils.
