Hi A.D.

Thank you for that information.  You sound somewhat knowledgeable about plant physiology.  I think that will be a great benefit to our discussions in this group.  Please remember to put the terrapreta at bioenergylists.org<mailto:terrapreta at bioenergylists.org> E-MAIL address on your posts, so that everyone else can see what you are saying.

Most soil micro-organisms live in the top 10 cm of the soil. The top soil is well aerated and the microbes also get their nutrition in this layer through leaves and flower petals dropped by the plants on the soil surface. This makes the top soil more fertile than the deeper layers of soil. Plants have to send their roots deep into the soil because that is where the water is. But they also have a network of roots that penetrates the top soil, because that is where the mineral elements are. In fact many species of plants wet the top soil in the night through a process called guttation and re-absorb the water through the network of roots present in the top soil. This mechanism makes it possible for them to obtain the necessary mineral elements, which are generally absent in the water that they get from the deeper layers of the soil. If charcoal were to offer a porous substrate for the micro-organisms in the soil, then applying charcoal to the top 10 cm would make better sense than applying it to the deeper layers of soil. 
Yours

  Hi Jeff,

  I can't say that I know anything about this.  I would think, though, that one could find a way to inject charcoal into the slot provided by a chisel plow, behind it for instance (if you even use this form of "low till" practice).  Anhydrous ammonia injection is of a liquid.  Possibly, you could pulverize charcoal into very fine dust, mix it with water, and inject it also as a liquid with the same or similar equipment?  Barring that, I would say that the charcoal needs to be "tilled"/"cultivated" into the soil.  Most, I think, consider incorporation to the depth of the root zone is ideal and sufficient (scary when you consider that alfalfa can root 15 feet deep?!).  Is it possible that the switch grass can survive being "tilled" with charcoal into the soil?  Maybe you could wait to let it go to seed, till the charcoal in then, water the shit out of it, and when the sprouts pop, put a little fertilizer on it?

  The "SPIKE" or the "NO TILL" injectors from NUHN look like the ticket for doing what you want to do.  I think you just need to make the charcoal into a liquid "slurry" maybe to use it in those equipment.

  Just some ideas.

    Dear List,

    Being a switchgrass grower I would not want to plow up the grass in order
    to add charcoal to the soil. I do not think that adding it to the top of
    the grass would do much.

    I do not know anything about these injectors so does anybody know if the
    below machines would inject charcoal into the soil but not damage the
    grass:
