    They actually just discovered a huge peat bog in the Republic of Congo. I heard this on NPR about a week ago.

    Side note, does that narrator suspiciously sound like a computer to anyone else? There is some really strange intonation and glitches in the audio that just doesn't sound right.

    Last product I tried that claimed to be inert, ended up leaching a lot. Contacted the company and they told the product was made to do that and plants love it. Ppm went from the 10s to the 100s within a few hours.

    I would also love to try the product. Sounds good but test before you plant.

    Nonsense, the locals knew it was there all the time.

    Well you gotta hide your child armies somewhere! Ok I even feel bad about that joke lol.

    Similar to that story and a few years older I just randomly read this.

    http://news.bbc.co.uk/earth/hi/earth...00/9359075.stm

    Apparently the Sphagnum subnitens in northwest America all originated from just one plant. As in ALL of the sphagnum is genetically identical to each other without any mutation. The same goes for New Zealand where two separate plants colonized the southern island. In Europe subnitens appears to be a ***** with as many varieties as you can find haha.

    As I posted in another thread...I used more peat moss on my lawn last year than in all my CPs.

    I'm much more concerned with issues such as commercial car washes being able to run during heavy water restrictions than I am about the peat renewable issue. I can easily grow/compost my own peat/sphagnum for my plants if/when its needed.

    There are a ton of good replacement products already out there if you feel the need to switch over, but all that peat is not going to CP/orchid/ect growers...its going on lawns/landscaping.

    If you really want to get depressed look at what gold mining is doing...and they are not even concerned about anything renewable...just strip mining, run off into streams/rivers.

    Considering the nature of the fossilization process, and the fact that coal is pretty much fossilized peat, you might want to walk back the assertion that peat is no more renewable than coal...........
    Because a peat bog can regenerate itself several times on a time scale within the lifespan of a human being, it is in the interests of the humans harvesting it to do so sustainably. There is no reason peat can't be harvested sustainably just as timber is. It takes longer to grow a harvest sized tree than to allow a bog to regenerate. Burning peat, like burning wood is essentially carbon neutral, and likely the text book you read was written with that in mind.
    That's pretty misleading. By completely ignoring spatial and temporal factors -- sure, what you say is true. If you look at a long enough time scale, sure, fossil fuels are 100% renewable! Likewise, since water isn't destroyed when it goes down my drain I may as well just leave the tap on. Thank goodness for the water cycle.

    While it is technically true that both peat and coal are renewable, sustainability is a much more useful metric. Renewability is a gross measure while sustainability is a net measure. Essentially, renewal rate minus usage rate equals an index of sustainability. While coal takes longer to renew, they both take pretty huge timescales. So huge that they are essentially negligibly different, especially when put in terms of current rates of use. If we could quickly regenerate meters of soil organic material we wouldn't be so concerned with atmospheric carbon concentrations. Just because we don't gain or lose C from our global balance (we'll ignore radioisotopes and meteorites), that doesn't mean we can just ignore it -- form matters! Water is great, but that doesn't mean that you would be equally excited in a pool of H2 and O2.

    My connection to to Cambridge Books Online is currently unavailable, but if you'd like to take a look at the pages Warren cited let me know, I should be able to access them. But really, you can look around the world for all the evidence you need (from the former prairies of the midwest to the highly weathered soils of the tropics) -- we tend to lose soil C much faster than we regenerate it. Come up with a good way for us to regenerate many meters of soil organic matter several times over the course of a lifetime and there's surely a Nobel waiting for you.
