This is the kind of activity that you would want to collectivize, because you need to develop a robust model to quantify change over time and account for differences among enrolled systems. There will be systems created, but they will cater to large corporate
land holders unless there is a strong stakeholder base pushing groups like NRCS to develop mechanisms for small land holders to get certified. Ultimately you'd be creating an interest in your property through a carbon sequestration easement, that will affect your ability to manage your land... so you'd have to define an area that you are willing to be subjected to this kind of routine.
An alternative is section 404 wetland banking, or ESA banking, both of which are in their infancy.
Here is an example of what it has been taking to get carbon credit certification for estuary restoration

In short, because you are putting your land into public service, you'd lose some land rights to insure the carbon outcome.
