RNCs - refundable nitrogen credits
Polyor SAS is developing an alternative to conventional carbon-credit & carbon-farming approaches to sustainable agriculture & soil organic matter (SOM) conservation.
A simple pTEC index (from the french, "progrès technique") indicates the precise amount of supplemental nitrogen allocated to the humification of post-harvest crop residues into stable SOM. Given that this nitrogen derived from the sustainable cropping practice being assayed is not harvested for profit but contributes to soil-organic matter conservation it is deemed ... "refundable".
These refundable N-credits are calculated precisely at the plot-level using Polyor's AgroNum AI-algorithm (https://lnkd.in/eBmfT3NM). AgroNum's nitrogen-fertilizer response curves being used as baselines, only crop-yields beyond this sustainable benchmark will contribute refundable N-credits thus avoiding the risk of free-riding and non-additionality (alias "greenwashing").
Polyor SAS will now try to standardize, via the #IFRS & #ISSB for instance, this precise & convienient metric of soil organic matter conservation as an alternative to conventional carbon-farming derived carbon-credits. Refundable N-credits, or RNCs, as proposed require no error-prone & at times expensive soil-sampling and are presently applicable across Europe. The RNC concept is work-in-progress, so contact Polyor SAS directly for info.
