  • What is Biochar and how does it work?

  • Biochar as a soil amendment enhances plant growth and reduces need for water and fertilizer. This is because more moisture and nutrients remain in the soil and don鈥檛 leach into the groundwater. Scientists believe that soil improved by biochar is more efficient, retaining critical nutrients such as magnesium, calcium , phosphorus and nitrogen.

  • Do biochar biofertilizers enrich nutrient enrichment?

  • In addition to the direct effects associated with the nutrient enrichment of biochar, the results from this study show that BBFs were, on average, able to further contribute to an increase in productivity beyond that of conventional fertilizers, especially when involving N fertilizers.

  • Can biochar replace chemical fertilizers in rice crops?

  • Biochar is an efficient amendment to improve soil quality and crop productivity, but the potential of biochar as a substitute for chemical fertilizers is still unknown. Here we conducted a 6-year field experiment to investigate how partial substitution of biochar to NPK fertilizers affect soil quality and rice yield in the northeast of China.

  • How does biochar affect soil nutrients?

  • Impacts of biochar application on soil nutrients Biochar can influence the soil nutritional status by its inherent ability to supply and retain nutrients and alter some other soil properties (e.g., pH, CEC, biological activity) ( Hossain et al., 2020; He et al., 2021 ).
