Abstract
Biochar is a type of pyrogenic carbon that can potentially contribute to agricultural productivity and environment sustainability by increasing remediation of contaminated soil and its reactivity. However, occurrence of biochar aging process disturbs its remediation role, because various surface attributes of biochar happened to be altered through different biotic and abiotic factors. In current review, several important factors critically affecting the aging process are discussed that includes soil physical, chemical, biological components along with soil temperature. It was noted that aging process in biochar might be accelerated by elevated temperature; soil components protected it mainly by soil organic matter through its interaction with soil microbes. To promote prolong biochar application in nature; aging of biochar can be better managed through its influencing factors.

Keywords agricultural productivity;biochar aging;environment sustainability;pyrogenic;soil microbes.
