My Soil Carbon Project

Last winter after attending an ag conference, where I heard Fred Provenza speak, I found the soil carbon coalition website, and began to learn more about the connection between soil carbon and ppm of CO2 in the atmosphere, and climate change.

In July Peter was here and took baseline soil samples.  I had him locate the test plot in the barest place in my field, as that is what I started with everywhere but the orchard and the original lawn.

Eventually, when he has time to update the website, you will be able to see my test plot on the day he took the first samples by clicking here.

Last week I gathered as much sweet clover seed as I could get from my plants and spread it in the area where I am planning to establish warm season grass and mixed pasture.  The soon to be pasture encompasses the entire sample plot for the soil carbon project.

Today I seeded big bluestem in that part of the field.  This post is just to record what I did.

First I cleared most of the weeds, made some creases, ran water, adjusted ditches and flow.

Today I scratched the surface, scattered seed on the down hill side of every crease, and the interior side of edge creases, and raked it to cover the seeds.

Then, because the literature says big bluestem likes it, I stomped it down, then ran water again, and again, and again.  I'm hoping to see germination in a week.  In warm weather conditions, it is important not to let the grass seed dry out, so its water, water, water.

The soil is warm enough for plenty of weed seeds to germinate, but few of the annual weeds will have time to set seed before frost.   Just in case they try it, I put out plenty of substitute weed seeds, purple amaranth, calendula, kale, arugula, radishes and a few others from my seed box. 

I have some more seeds to add, but I will wait to list them until they are in the soil.

Rocket Stove Part Three


The greenhouse is either construction zone or plants or thermal mass barrels of water.  It is hard to move around in there, and I keep resisting the urge to move some things outside, like barrels of water or stacks of pavers.  But everything in there is holding warmth, and anything I put outside will take its inherent heat energy with it.  So, I move it out of the way, again and again.  

Tomorrow,  I'll clear some material out of the way by putting it in place.  I will insulate the heat riser, rebuild the clean out, place the barrel, cob in the heat exchange pipe, and add mass.  I'll cut an exit hole for the stove pipe.

The clean out access after 3 designs, and before cobbing.

Treasure!  The fourth load of stone given to me by my generous neighbors.  I've unloaded all the stone, and sorted it by color and type, and now that it is spread out in the snow, we have new snow predicted.  Of course.  It will be good to have the water.

Greenhouse Heat part 2

I did do my test burn today, but before I did,

I put in the row of booster bricks, to raise the barrel up.

And built the clean out / ash pit room.
I mortared in the bricks to complete the row, and covered the top, set the barrel in place (without the insulation, in case it doesn't work, and I have to go back and rebuild something.)  

I missed a few pictures today, my hands were muddy most of the time.   But there is still plenty to do, so I will get pictures showing the top all sealed up, and the barrel in place.
  Below, you can see the top of the barrel, and the pipe carrying some of the smoke out the door.

It did burn, it did draw smoke up the riser and down the inside of the barrel, into the ash pit /clean out, and on down the pipe, but it was smoky.

Ianto says smoky is to be expected when the stove is cold and wet,  so I think I have a workable combustion unit.  The top of the barrel was warm to the touch, air went in the intake.  Flame went down the burn tunnel.  And steam rose off the wet mortar from the top of the burn tunnel to the place where it disappears into the riser assembly.

I had a helper today.  Maxi-Cat.  Here, he is checking what is on top of the worm bin.

 Here, resting in between inspecting my work.

January 2013 Project, heat in the greenhouse

It's been COLD.  Below 0 more nights than not since before Christmas.  It's been so cold that when it warmed all the way up to 38 F one day last week, it felt positively balmy.  You know it's been cold when 38 feels toasty!

The day time highs have been in the 20s on a warm day, and there is snow on the ground.  On a sunny day, the greenhouse heats right up to mid 70s.  On a cloudy day, or a snowy day, it gets up to 40.  That's not bad for solar gain on a day with no sun and the outside temperature in the 20s, but I want a greenhouse that's warm enough for the 3 pots of Moringa oleifera who don't like it colder than 40.  I want it warm enough for the rose geraniums and lemon verbena.

Starting in late February, it will need to be in the high 70s to germinate tomato and pepper seeds.

I am building a rocket stove mass heater, something I learned about in 2003, when I took a cob building class with Ianto Evans and Linda Smiley of Cob Cottage.  

Most people build rocket stoves with collected materials, so I made a tour of the junk yards, the re-store, my garage.  I called the oil change places and mechanic shops until I found a barrel.  I gathered brick from my garden.  I read and re read the book , read the whole wood stove forum.  I would lie in bed in the morning before getting up, at night before sleeping, imagining how the air would flow, how it would go together.  I tore up the floor in the back third of the greenhouse.  Pavers, dirt, tarp, rock, tarp.                                            

Here I am using my materials to plan.  I understand the idea, and have got the right dimensions and proportions in mind, but spatially, it's a puzzle.  Always has been.  Playing with building blocks  I would disassemble and rebuild a thing several times, because I could not visualize the completed thing, had to see how it went, then go back and add the needed pieces, once I discovered I needed them.  Here is that same thing again.  Build it part way, and then discover what it was I did not yet understand.  Luckily, the experts all say to build a "mock up"  exactly what you plan to build, to see if it will work, so  I guess maybe I'm not the only one who doesn't get it the first time.

Yesterday, I leveled a pad and began.   At the end of the day, I had mortared the feed hole and the burn tunnel and the bottom of the heat riser.  The stove pipe is just resting on top of the bricks.  It was a good stopping place.  I wanted to let the mortar set up.  The sun was down, and it was getting cold.

Today had lots of puzzles.  The heat riser needs insulation, then a barrel.  The silver tube will hold the insulation, but the space between the insulation and barrel is critical, and I could not see how the fumes would get out if I set the barrel on the bricks, and if I did not set the barrel on the bricks, then what would hold it up?

The clean out walls are in place.    Whew!  And with my black circle the diameter of the barrel, and my cut up pieces of measuring tape, I  measured the space where I hope the fumes pass into the clean out and thence to thermal mass.

At this point I think I'll raise the barrel up 4 inches by setting a course of bricks on the side, and I will build that course to the outside, leaving space for the fumes.  Three improvements.  Extended the heat riser, increased the cross sectional area for the fumes exiting the barrel, and created a support for the barrel.  Yay.

Canyon Wren Farm Is Open to Guests

This historic farmhouse is ready to be your home away from home, to shelter you in comfort while you read, write, paint, sketch, or just enjoy the view.

Or, return after a day exploring the valley's wineries, microbreweries, farms and farmers' markets, hiking, biking, walking, running, riding, swimming or paddling. High desert, or alpine meadows, and everything in between is accessible from our door.

Mountain biking in the Fruita Region is second to none. The Kokopelli Trail begins its 142 mile ride to Moab, Utah, in nearby Loma.

The guest area includes a living room with attached deck
Two bedrooms

and bathroom with soaking tub.

Through Canyon Wren Farm, arrangements can be made to stay in the Three Sisters Ranch guest house, an off-the-grid mountain cabin at approximately 8000 feet elevation.
