Abstract

In the current study, prosopis wood material was pyrolyzed at high temperatures to create biochar, which was then characterised. A laboratory closed incubation experiment was used to investigate how biochar affects soil properties. The prosopis biochar that was created had an exchangeable acidity of 49 mmol kg-1 and a pH that was neutral. A 16 cmol kg-1 cation exchange capacity was present. In comparison to nitrogen and phosphorus, it included a considerably higher amount of potassium (K). (940 g kg-1) of carbon was present, which was unusually high. The high porosity structure of biochar, which has the ability to improve water retention and increase soil surface area, is one of the main qualities that make it appealing as a soil amendment. While a soil's pH dropped as low as 7.92 after being added at various rates of biochar during incubation, the soil's cation exchange capacity (CEC) was shown to have dramatically risen as a result of the biochar addition. With an increase in the rate of biochar application, the soil organic carbon (SOC) significantly rose, and it continued to rise during the 90 days of incubation.

Conclusion

The properties of biochar specified by chemical and physical processes reveal the infrastructure of biochar. Biochar defined by its useful application to soil, is expected to enhance an advantage from enduring chemical and physical properties. For large surface area and porosity of biochar, they can raise the capacity of water holding of soil and the absorption of nutrients with a view to decrease loss and an augment soil structure, so biochar might progress fertility of soil and raise crop yields in future if it is applied to soil with a suitable application rates.
