Oxalate Carbonate Pathway

Can anyone tell me more about the Oxalate Carbonate Pathway (OCP)?

I have learnt enough to understand what it does and it seems to be a viable method to sequester large amounts of carbon.

My next step has been looking at the best plants to grow on a mass scale in order to make use of OCP.

The first plant I came across was Mvule (Milicia Excelsa), which appears to be the most efficient tree in terms of OCP, however also seems to be more of a lone grower so perhaps harder to farm.

My latest interest has been cacti, specifically Opuntia/nopal (prickly pear). From what I can gather this is also very efficient and producing calcium carbonate and, unlike Mvule, much easier to farm on a mass scale.

Is there anyone on here that knows about OCP, especially when used for carbon sequestration, and would be able to answer some questions for me?

As this may be an option for investment I am very keen to find the economic potential of growing a farm, perhaps of Opuntia, for use as a "Carbon farm". That being said, anyone with knowledge of Opuntia being used for Carbon sequestration will also be of great help.

I look forward to any responses! Thanks in advance.

The most important thing you need to know about the oxalate carbonate pathway, is that
FUNGAL activity increases this nutrient exchange between soil and plant.

So...Focus on increasing the mycorrhizal+mycelial networks in the soil to capitalize on this “pathway.”  Try not to get hung up on some species that some scientists says has a higher oxalate-carbonate pathway...

When you DO choose a carbon source to farm, consider the long term provisions, too. We don’t carbon-farm strictly for the sake of farming carbon, we have to feed people too.  

So one of the most important questions you can ask yourself, is: What would you/your inheritors do with the product?

Could they eat an entire farm of prickly pear? Or could they sell Timber or build homes with African teak after a couple decades?

And even still: Beware that you don’t fall into the modern mindset of monoculture!

One big field of primarily just one thing, isn’t very good for any of us... I encourage everyone to deeply consider the synergistic polyculture that could be created with the same amount of effort as a massive forest of cactus...
