Summary
The practice of applying biochar to soil could increase crop production and sequester carbon, whilst tightening leaky nitrogen cycles. Biochar has been shown to improve soil properties and even reduce greenhouse gas emissions, however the underlying mechanisms that lead to yield increases and GHG mitigation still elude us. Recent and ongoing studies have demonstrated that detailed analysis of the inherent biogeochemical processes using stable isotope techniques can unravel the complex soil–plant interactions and begin to tease out the multifaceted impacts of biochar on soil processes and plant growth. Here we present a range of nitrogen isotope techniques that could be, or have been, used to understand the changes in dominant processes in the nitrogen cycle following biochar addition.
