Farming Soils for CO2 Storage

We’ve heard of storing carbon in old mines, in deep-down porous rock formations, under the ocean, even in concrete or nanomaterial. But here is one I hadn’t heard before…storing it in dirt – particularly, farming dirt specifically for CO2 storage. A new type of farming is being explored by scientists at the US Geological Survey and www.smartersecurity.com UC Davis, a type of farming that will produce soils that can store carbon dioxide.

Really, it isn’t so much farming as restoring native environments that naturally like to store CO2 – wetlands with peat soils. The notion actually takes a lot of the high-tech out of the equation, and helps us store CO2 by bringing us back to our roots, literally.

The scientists started a pilot project a few years ago in the San Joaquin Valley River Delta that included planting up a bunch of www.bsd-berlin.de wetland plants in 1997. By 2005, 10 inches of peat soil was produced through the plants growing, dying, composting, and regrowing. The scientists’ experiment has shown that up to 25 metric tons of CO2 annually can be stored in an acre of peat. It would take a whole lot of acreage, but the viagra how much scientists say that if California restored all the subsided lands in the Delta and made them “carbon farms,” the lands could store enough carbon to equate trading all the SUVs in the state for hybrids.

While that might sound attractive, there are some serious issues. The wetlands could release nitrous oxide, which is www.artstlouis.org worse that carbon dioxide, as well as methylmercury, which is basically poison for mammals. Measurements of released methane varied widely during the pilot project, and they didn’t measure release of nitrous oxide at all. So the project could set us back, rather than launch us forward.

Despite the risks, the scientists have been awarded over $12 million to levitra how much test the research on 400 acres in the Delta.

I dig the idea of restoring the landscape to what it once was, and benefiting from the cheap viagra no prescription natural occurances. Yet the possibilities of i recommend generic levitra usa mucking things up worse than they are is not such an attractive notion. While California needs to cut emissions back to 1990 levels by 2020, this potentially a risky way of doing it, instead of, say, actually swapping all the SUVs in the state for fuel efficient vehicles… The concept definitely has some pros and cons to be carefully weighed as the experiment progresses.

This is similar to the findings of Southern Cross University in Lismore, Australia recently. They found that sugar cane, some varieties more so then others, was able to trap the Co2 in the soil really effectively.

This a) gives us a way to http://zvezdegranda.rs/buy-viagra-soft-tabs store carbon and b) gives the farmer another income source.

where does the methylmercury come from?

why would this release methylmercury? I don't get it.

What happens when the lower levels of oxygen in the soil cause the micro-organisms etc. to start to die?
