Anaerobic Compost Experiment
I have a story about okra. It is a true story, but I have no photos to back it up. It has to do with hungry okra, grass clippings, grass catchers, and compost. My husband bought a new mower last year along with its grass catching equipment, but prior to that, he had a large walk-behind mower that did not have a grass catcher. Even before that, he had a riding mower that had a grass catcher. This was around 8 years ago. One spring he caught the grass clippings and dumped them in the woods. A few days later, we smelled sewer odor. At first, I thought it was the neighbor’s yard because they sometimes have problems, but later I discovered it was the pile of grass clippings.
Shortly after that, perhaps 6 weeks, I went to the woods to retrieve some compost for the okra. I had a couple of plots of okra planted in the square foot gardening style. I found under the grass clippings that had stunk gooey black stuff. I gathered some of it and placed it around the okra. When the gooey black stuff dried, it was powdery.
The okra grew like wildfire after that and by August, I was using a stepladder to pick it. No kidding, some of the okra had grown 9-10 feet tall, and of those, the okra trunks were so thick I couldn’t wrap one hand around them.
The following is what happened and why the stinking pile of rotting grass was so good for the okra.
A name for this type of composting is anaerobic. Apparently, the conditions were right for a high heat inside the grass clipping pile. A part of the pile, the middle, was partly closed off to oxidation and produced a lot of heat. The grass clippings composted at an accelerated rate and retained a high amount of nutrients, nitrogen for one. The whole pile did not compost in this way, just a part on the inside of the pile. As a result, it produced very little of this super-compost.
Now that my husband has a mower with a grass catcher again, I asked him if he would use the grass catcher (he does not always use the catcher) and dump the clippings in a spot in the garden. He did that Friday, May 30th.

And now the great compost experiment begins.
I love experiments, but there is a purpose to this. I need a rich source of organic fertilizer for the okra that I am growing this year.
Last night I used our foot-long chemistry thermometer and took the temperature of the pile.
Last night: 45 Celsius (113F)
This morning: 54 Celsius (129.2)
Then I covered the pile this morning. I used 4-mil clear plastic, which I just happened to have. I buried the edges all around with dirt to block as much oxygen as possible. The pile was already starting to smell.

I will be looking for several things:
- smell (pile will produce methane gas)
- temperature (or maybe not, I don’t want to break the plastic)
- how long it takes
- if it makes black goo
I estimate that the pile is around 15 cubit feet. The composting should break it down to around 25% of that which could yield around 3.75 cubit feet of compost fertilizer. That is, if the entire pile breaks down and I hope that it does.
If it breaks down the way I want it to break down, it will produce nitrogen rich black goo. I will feed that to the okra plants. Okra is a fast growing nitrogen-hungry plant. I suppose if the compost breaks down into goo, the okra will become an experiment on the side.
We’ll see!


Awww. that is so sweet. And you have all those..."
Dr. Wile has published a 2nd edition of his general science curriculum. This is to announce that I've made a schedule planner for this book. It is linked below.
You’re the coolest, Donna.
May your experiment be successful!
You could bottle it up and call it Donna’s Black Magic Goo.
I love reading about your experiments
Black Magic Goo
Even though it has only been around 12-14 hours, it is looking good so far.
I found a way to measure A temperature, not THE temperature, but I guess it will have to do. Anyway, By pushing down in a place near the top of the pile where the plastic is flappy, I can get a shallow temperature reading of the top of the pile. I guess that is better than no temperature.
The shallow temperature of the pile was 147.2 ºF.
Pile height is 18.25 inches as of tonight. I forgot to measure it earlier.
And there is no odor! I’m very glad about that for our sake and our neighbors’ sake.
From that clue, I suppose it is air-tight.
Since it is air tight, you won’t get to see it smoke.
Looking forward to hearing more about this Black Magic Goo. 
For a shallow temp. that is pretty warm, Donna. This should be really interesting to keep track of and see what happens.
