Changes in Fertilizer Management
The American Carbon Registry (ACR) has published a
The methodology details requirements for quantification of GHG emissions reductions in the agriculture sector resulting from changes in how fertilizer is applied and used. It incorporates site specific data into a peer-reviewed, tested and highly parameterized model, the 2O emissions as well as indirect emissions from leaching and ammonia volatilization., to quantify direct N
This methodology is applicable to Agricultural Land Management (ALM) ACR project activities that involve a change in fertilizer management including changes in fertilizer rate, type, placement, timing, use of timed-release fertilizers, use of nitrification inhibitors, and other factors.
ACR has closed the public comment period and initiated scientific peer review for v2.1 of its Methodology for N2O Emission Reductions through Changes in Fertilizer Management. Upon final approval and publication this version will replace v2.0. The methodology’s purpose, scope, applicability conditions, eligible practices, and quantification approach remain unchanged overall. ACR has made updates and clarifications to improve the flexibility of the methodology by providing eligibility criteria for other greenhouse gas quantification models in addition to DNDC. Upon final approval and publication this version will replace v2.0.
