Yes, absolutely.
The 4R nutrient stewardship is really this suite of best management practices: right source, right rate, right time, right place. They really help us reduce nitrous oxide emissions among other things, such as water quality, etc. The role they have to play and how they're linked with NERP protocol is really important.
One of the things we're exploring in our carbon program is engaging growers at all different stages of implementing the practices, from advanced growers to growers who are looking at the basics. The 4Rs are really outlined in that way. There's a basic, an intermediate and an advanced level. We work with all of those growers to see how we can continue to advance on practices.
As I mentioned before, there are some costs when you get into the intermediate and advanced practices. Growers might not have everything they need to calculate variable rates, which is a very good practice, but maybe they don't have all the equipment, etc.
We really help by working through those barriers, making the plan, and then combining that with soil organic carbon protocol work and other products to get the full carbon asset out of the farm operation.
