Garden Adventures
Hurrah! I have a real compost pile going. I followed the general guidelines in Steve Solomon’s book, Gardening When It Counts: Growing Food in Hard Times, see . I made it big enough and layered it properly with garden soil to inoculate with soil microbes and cottonseed meal for extra nitrogen, and watered it properly with rain water plus some urine. It has heated up to 150ºF nicely. What inspired me was Steve’s suggestion to accumulate compostable brush in a pile over the season and let it dry. Then in the fall construct the compost pile. I’m a few months late, but I had the piles of dry stuff to work with, and it should compost quickly now, with the approach of warm weather instead of winter. When it’s finished I’ll mix it with some Complete Organic Fertilizer, for a high quality soil amendment.
I’m experimenting with another soil amendment – some biochar. Charcoal has a remarkable ability to hold trace minerals in it’s structure, as you can see here and is very long lasting compared to compost. It is the foundation of some excellent historic garden soils found in the Amazon, called terra preta. Since I have a sizable meadow area with lots of last years dry flower stalks, I have lots of potential biochar. The customary way of getting rid of the dry flower stalks in a prairie is to burn the area – not practical in my confined area. So I came up with a way of burning them that works quite well to make biochar. I took an old rusty barrel from behind the garage, and to confine the heat and limit the air intake, I put an old rusty garbage can in the barrel. The rusty holes provided plenty of ventilation for the ‘pyrolysis’ stage of the burning. I stuff the garbage can with broken dry stalk and light the fire with a wad of newspaper and a match. Then as it burns down I break up more stalks in short lengths of about a foot and pitch them into the fire carefully so as they burn they settle down into the pile of glowing embers in the bottom of the can. When I have a fair amount of glowing coals, I let the fire die down and put the lid on the barrel to limit air access while I get some water. Then I douse the coals with water and put the lid back on to let everything cool. The next day I dump the char into a bucket and charge it with fertility by pouring on some nutrient rich liquid – urine works fine – and letting it soak. Now it’s ready to mix into the garden soil. Scattered lightly around the base of cabbage plants it’s reported to be a good snail, and presumably slug, deterrent. Maybe the squash bugs won’t like it either!

  1. I'm loving you website, blog, all your links so much that I am having to pull myself away from the computer again today. (I actually ran across your Gardening for Maximum nutrition site before I even learned about WAPF and then this year when I went through my favorites looking for it, decided to "hunt down" the info since the old link was dead, I rediscovered you.) Anyway, Thanks for all your info!!!!!
    I thought I'd share something since you mentioned learning/doing more on the computer.
    When composing a post, If you highlight a word or phrase, and then click the little hyperlink button above the text box.(looks like a green ball (globe/world/earth) with a weird design above it(chain links/WWW(world wide web)link)) Then type in your url, you won't need the "tiny url" because the word will be the link, The color of the text will show that it is a link even when the mouse isn't over it. (hovering over it will show the url in the bottom left corner of the browser window (called the Status Bar under View in Mozilla).
    Hope you don't mind, I thought You might like that tidbit.
