Not to mention all that carbon released when the wood decomposes - no ?
- mikeg8 5y agoNo expert here but I believe it depends on how it decomposes. If wood rots at the surface, my understanding is more carbon is released into the atmosphere but if it is buried or decomposed using fungi or soil microbes, more carbon is captured into the soil. Forests have a lot of decaying and decomposing deadfall wood but still seem to be a carbon sink so it may be a layering thing...
- spfzero 5y agoThat's the reason you use wood chips and bark for mulch in a garden; to add carbon to the soil.
- canadianfella 5y agoDo you have a source for that? That sounds wrong.
- psd1 5y agoIt isn't the usual primary reason. You use these things to provide a mulch layer over the top of tilth; it suppresses weed germination. If all you want is to add organics, you'd probably fork in manure.
- booi 5y agoBy released I assume you mean into the air? I think only if it's burned?
- noselasd 5y agoIt was captured from the air when the wood was grown though - so as long as you maintain the forrest you took the wood from it works out.
- mensetmanusman 5y agoNo, not all carbon is released as gas during decomposition. If it were, we wouldn’t have diamonds :)
- burnished 5y agoI don't know enough about diamond formation to properly dispute this, but I thought they didn't form from organic, locally sourced carbon?
- ajnin 5y agoYes, that's why planting trees to offset carbon emissions is not really as good an idea as it seems, trees can live a long time but they're not immortal, and when they die they release their carbon back into the environment.
- robotresearcher 5y agoIf you leave them alone to make baby trees, they can be an amortized constant capture or better. Meanwhile they liberate oxygen, which I enjoy daily.
- pxndx 5y agoIf you turn what now is barren land or grasslands into a forest, it absorbs CO2 as it grows, and that CO2 stays captured for as long as that land is a forest, it doesn't matter if individual trees die and decompose.
