Involucres and obtaining a yield

 I just finished harvesting the hazelnuts this fall, and so will share how that went.

The first planting was in 2012, but we weren't living here yet, and when the drought happened that year, we could not figure out irrigation. Nearly every single seedling died back to the root, but most came back next year. So they are tough, but had a big setback. They are native to the region, and normally rainfall is adequate, but a drought year is tough on brand new seedlings that had not had time to set roots well.

Care has been minimal. They have received no fertilizer or water, and were planted directly into untilled pasture.

 I do mow next to each row to reduce the competition a bit from grass and other annuals the first couple years, but now that they are larger, I just mow to make access easy and stop woody plants from migrating over from the woods. The ash, prickly ash, box elder, wild grape, sumac, and briars have plenty of room to play elsewhere. 

These plants were from Mark Shepard's nursery, so they are from his best plants, but were neither controlled cross nor propagated, so the genetics are only roughly predictable. The variation in plant shape and productivity is large. Many plants have no nuts at all yet, and some are prodigious. Overall, it's a chore to hand harvest

Without the initial setback, and more intensive management, they would be in full production by now, but are still ramping up. That's ok, I am intentionally trying to see how this food crop will do with as little fossil fuel input as possible.




       
Here are two typical plant shapes with decent nut production. Note that there are a lot of nuts under leaves that you can't see.

Taller, more tree like, nuts scattered along the stems.



shorter, bush like, nuts mostly at the top. That's goldenrod in the row, blooming. The bushes will eventually shade them out more completely.


I used harvest bags similar to this:


and nearly  filled two bins (45" x 48" x 30", 1140mm x 1220mm x 760mm)  like this:



I kept back a few pails worth for hand processing and making home made hazelnut chocolate spread, but most went on to Mark, who has been developing farm scale mechanized processing equipment.

Which brings us to involucres. This particular nut is mostly enclosed by a fleshy covering that wraps around the nut, and slowly releases as the nut matures and starts drying. They are basically a type of husk. I guess it is some sort of evolutionary adaptation to give a bit more protection from insects to the nut?

Since I harvest when the involucres are still a bit green, the nuts don't pop right out easily. If I waited longer, many of the nuts would release and fall to the ground, greatly reducing harvest efficiency. So after the nuts dry a while in our sunroom, I remove husks by hand, which is time consuming. All the time I'm husking, I'm thinking there must be a way to mechanize at even smaller scale than currently being worked on. Like a household gadget similar to a grain mill. Maybe a good winter project for the workshop.

Permaculture design principle #3 is obtain a yield. That struck me as funny the first time I read it, seems obvious, but it does point out that as a food system, at the end of the day, calories out have to be more than calories in, or the arrangement won't continue. All the hand work I presently do is exploration, but at some point, I will need to tot up both sides of the ledger and see how well I can do as I scale up.

The hazelnut spread is quite good, and no palm oil!

wheat from our garden

A long delayed post:

To start, I am terrible at photo documentation of progress here. Didn't get any shots of the wheat before harvest, or the piles of wheat in racks, drying before threshing.

In fall of 2018, we planted red winter wheat in a section of our garden. I checked on planting densities, weighed out the portion required, and then hand sowed it as best I could.

The stand turned out quite well, crowding out weeds, healthy all through the summer, and dried well, no disease or lodging.

What did not turn out so well was the scything. I had taken an intro class on scything two years ago, but failed to put in the hours to refine my technique. I also studied various simple cradle attachments that others had come up with, and picked a simple one to do.

This fellow's technique and attention to detail on his cradle is worth viewing, and I may try this same design again, just doing it better.
https://www.youtube.com/watch?v=cF0kdhIcG7U

I ended lip using a sickle to harvest about half of the wheat since I was making such a mess of the scything. Using a sickle is slower, and you have to bend over a lot, but wasn't that bad for the small area I was working with. Would't want to feed the village that way......

Getting the fanning mill screens and settings right was tough, and the thresher I made following another concept found on line did not work as well as I had hoped.

Nevertheless, I did end up with a nice quantity of grain, it just still has a bit of retained hulls I need to remove. I have two five gallon buckets (roughly 30 kilograms) of wheat berries, and will grind as needed.




So, this year I decided to give oats a try. Things got worse.

Winter wheat at my latitude is planted in the fall in prepared soil, sprouts and grows a while (timing of sowing is important) and goes dormant in winter. In spring, it restarts, getting a good jump on many of the typical warmth loving weeds. A good stand will crowd out weeds, and make it easier to harvest.

Oats do not overwinter, and are planted in the spring. My hand sowing is not perfect, and the oats did not get a head start on the weeds, so the stand was spotty and had lots of weeds. Luckily, I planted a much smaller area, so the loss was not as bad. I also chose a hull less variety, so maybe it is not as vigorous? I don't know.

But......I finally took more photos.

Here is the thresher I built. When the lid is closed, the shaft spins the wooden beaters, and grain is fed in through the little windows one handful at a time. I also built a bike powered attachment, but then you need two people to thresh, and it gets TIRING.



Here is where I "borrowed" this idea.
https://farmhack.org/tools/bicycle-powered-thresher


Here are some to the oats, bound and dried.


Traditionally, grains are stacked in shocks, and left in the field to finish drying. Stacking properly is a fiddly thing, and I did not have that much, so I put mine on racks and sun dried out next to the barn. If rain was forecast, I moved back in the barn till sun returned.

I found that the hulless oats were generally hulless, but again, a percentage did not release from their outer husks, so I have some more processing to tinker with.

In general, I have been making our farm into a perennial based food system, but boy I sure like grains. I also like the long term storage properties of grain. These will continue to be small, side ventures, I'm trying barley next.

Toilet paper guilt

Recently, I read another article bemoaning the vast tracts of Canadian temperate forests being cut down and pulped to wipe our soft American bums.

This is not a new issue, and I have read similar articles in the past. Not much has changed.

We buy the recycle stuff most of the time, for added cost, but is there another way? How do people clean their anus in other countries? How did people do it here in the U.S. before mass consumer products started rolling out?

A quick visit to wikipedia and we find that toilet paper was actually first used in China in the 14th century. One more time we find that Western countries had a lot of catching up to do. But, I imagine the paper was mostly used in  the royal courts and wealthy homes.

More perusal of the wikipedia shows that people will use just about anything. The list is crazy. I guess if I could find some substitute that was effective and comfortable ( and with less impact to the environment), I'd be wiling to try it.

Last year, When we harvested our sweet corn from the garden, I saved some husks, and actually sorted through them finding mid layer husks that were softer that outer husks, but still large enough to be usable. I then flattened them and used sissors to cut them in to squares. They are still sitting in a box in my workshop................

But back to that guilt thing. I guess for me, and maybe many others, it's not so much guilty feelings, but rather a feeling of unease.


Update Apr 7, 2020:

I started this post months ago, and just left it in my draft folder, as it didn't feel finished, and it was goofy topic anyway. WHO KNEW!

With the current pandemic, we've now had TP hoarding, shortages, and articles on various alternatives to the current first world use of virgin tree fibers. While we try to use recycled TP, it is still a cost, and I wonder how much better it really is.

For, now should it come to it, Guess we may switch to "family cloths". Maybe in combination with a bidet? Since I already use a composting toilet, managing the ick factor is minor.

Anyway, the guilt is still there, because why haven't I switched already?

quick note on climate control

It is now late winter here, and the sun is gaining strength, climbing higher in the sky, and days are getting longer.

BUT, it is still winter, snow is still on the ground, and the average March will still get 7 inches ( 180mm) of snow in our region.

We are fortunate to have a large sunroom along the south face of our house, gaining warmth, and a good place to start garden seeds. 

When we have sunny days, and when it is warm enough in the sunroom, we open the sliding door, and let warm air enter to replace burning wood for the day.

How to know when it is warmer in the sunroom than the house? I have a very sensitive temperature differential sensor, and when it signals good conditions, we open the door, and monitor the sensor to know when to close the door in the late afternoon.

It's a bit low tech. I taped a small length of black thread to the top of the door jamb, and if the thread starts being blown in to the house, I know that warm are is moving in to the house in the upper half of the doorway, and relatively cooler air is flowing from the house out in to the sunroom in the lower half of the doorway. When the thread is no longer moving, or even showing flow out in to the sun room, it's time to close the door.

Yay for the buoyancy of warm air.

hopefully you can see the thread in this shot, showing warm air entering the house.

The life of a tarp

A tarp is a handy thing when you want to keep something dry, but don't have an industrial sized warehouse in the back yard. Now that we are hobby farming/homesteading, we have acquired some "stuff".  Some of it won't or shouldn't fit in the pole shed, and some of it is just temporary. We also heat with wood, and it should be kept dry to make the most of it. If I've split more wood than will fit in my storage sheds, I tarp it. (time build another wood shed!)

While it's not that green to go buying things made of plastic, I"m not a purist, and will buy things made of plastic when the need outweighs my desire to consume less.

There are actually several life stages of a tarp. Tarp in its initial setting sits on a shelf in a home improvement or hardware store. They used to be only blue, but now come in several colors.  Once purchased by the typical home improver, they might be used for about anything. They come in light duty, medium duty, heavy duty, trucker industrial duty, good old canvas, and even one called recreational. I have never had a recreational tarp, but suspect they are pretty flimsy, more for casual frippery and nothing serious.

While it depends on the application, I generally buy a medium duty, trying to go for the eternal compromise between short term and long term economics.

When a tarp is put to its first use, it is pretty much waterproof, and I use them for covering things that need the best protection, or that probably really should be stored inside. But after a few months, or a season, the wind and sun takes its toll. They begin to wear, and you can see wrinkles, light streaks of discoloration, and maybe even the beginnings of light showing through in pinholes. They are still pretty good, but might be leaking a bit, so moved down the hierarchy to slightly less demanding duty.


This new tarp is protecting a new electrical wood splitter we just bought. The splitter will get its own post later.


This tarp is protecting our grill/smoker. It's a bit older. but still in good shape.




Another season or two, and now they definitely leak, but only in areas, and most of the surface does deflect rain. Can still be used for things that can stand a bit of water. Maybe used for temporary coverage, maybe to cover a tiller or brush mower that ran out of gas before getting to the shed. Or covering a load in the pickup truck on a trip that threatens rain.

After another year or two, it is definitely tattered, and you wouldn't want to count on it for shelter in a rain. By this time, it is good for gathering leaves to drag to the mulch pile, or to catch wood chips shooting out of a chipper, but not much else. It can be in this stage for a couple years, if stored when not being used.

Once large tears have developed, it's pretty much useless, and time for the trash. They are effectively unrecycleable here.

Recycling has always been a bit of a conscience salve anyway, rather than a true implementation of a circular economy, but it has become even less effective since China stopped taking our poorly sorted detritus last year. I suspect much of it is going in to landfills now, but reducing plastic use can be hard to do completely.

I'm ready to try the used old billboard tarps next time I need new tarp. While they don't recycle either, at least I'm repurposing some plastic. Until I can figure out a better, more sustainable way, I will use tarps for temporary wether protection, and just use them for as long as I can.

Energy flows

It is winter here now, with about five inches ( 127 mm) of snow on the ground, with wind chills around zero F ( -18C). Pretty typical for a Wisconsin winter.

Plenty of activity around our bird feeders, especially the juncos hopping around on the ground. Since retirement, I spend a bit more time just watching and trying to grok the natural world around me.




The thought that keeps coming to mind as I watch from my warm home is how amazing it is that these little balls of fluff can survive and thrive in the cold, with so little food easily accessible. They enjoy the bird feeder, but do just fine without it. Their existence proves that their ancestors for millions of years managed without birdseed from the hardware store.

The same applies of course, to the other creatures that stay active all winter, but to me these little guys epitomize the ability to find a way to survive in marginal conditions. Heat loss is a function of the ratio between volume and surface area, so small birds are playing a tough hand in that respect.

The world, and the universe itself, for that matter, is a big old entropy generating engine, and we are all busy doing our part, consciously or not. I imagine there is some soil bacteria species that will find sustenance even in the tiniest spec of junco poop.

I'm no paleontologist, but my mental image of evolution goes like this:

The planet has many different energy flows happening continuously, with sunlight being the main one driving living systems, once plants figured out how to photosynthesize. Boy, wasn't that a great leap forward.

Then, as plants multiplied and got to crowding each other, evolutionary forces kicked into overdrive, with some plants growing taller to grab the sunlight first, or others changed other features to get enough energy to reproduce.

Before you know it, the tropics were packed, and some plants figured out how to withstand freezing by going dormant each winter or changing their internal chemistry. Thus plants crept toward the poles, covering more and more of the land. ( hmm, wonder what might have happened without our 23 deg. tilt?)

Insect and animal life came along over time, and they all figured out a way to harvest energy and reproduce as well. All along the way, more and more subdivided niches were filled, as one species or another found an energy flow to exploit.

And then Homo Sapiens came along. Our unique assemble of traits mean we are a generalist that can exploit many energy flows. Even fossilized carbon from millions of years ago. Oh, we'll finish extracting all that energy soon, and the food web will adjust accordingly.

The thing to keep in mind, with all these energy flows, is that each species finds a balance between population levels and the energy flow they are a part of. At the geological scale, our use of fossil carbon is a one time brief blip, and our numbers will readjust to the available energy, as the food web hopefully restabilizes in a complex, diverse new balance.

I'm thinking juncos will still be part of it.

demand side power management

This is a thought experiment on how a local community might utilize electricity on a completely solar powered resource.

The obvious changes and limitations from our current arrangement are radically less energy available, and much restriction on when the power is even available.

But let's say that we want to ( or simply must) power our village, town, or neighborhood with only solar power. Till now, it seems all focus is on how solar could replace fossil energy as we are currently used to using it. That ain't going to happen.

Rather than figuring out matching power output to demand, what if we matched demand to supply? Individual off gridders already do this, and seem to get by fine, though with different habits and patterns than the rest of us. What if a neighborhood or small town did this collectively?

It might look like this.

The power grid gets divided up into many microgrids, with optional connections to the wider grid.

All homes have solar panels if homes are situated correctly.

Some shared solar farms could also be part of the generation mix.

All energy users have smart meters, as well as smart disconnects, meaning a central coordinating function controls where and when available energy is routed if needed.

Someone(s) in the collective could manage and maintain the system. There doesn't have to be help from some distant on call utility office. This will be a big step toward self reliance.

Some sort of equitable allotment scheme would be created, and then schedules and rules would be followed which basically gave each household a turn at the power so the generation does not get overloaded by demand.

This really goes against the normal individualistic mind set and culture of America, but when the end of easy energy looms, compromise and collaboration may well be forced on us as the alternatives would likely be even less palatable.

The thought experiment gets interesting when you try to imagine what the fair rules and scheduling might be. How to share cost, how to allocate power- by size of family? Strictly by ability to pay? Some mix? What about medical needs? How might time slot trading work? What about time of use pricing, or peak use pricing?  Lots of questions come to mind.

How would you rearrange your life to use electricity only for certain stretches, and in only partly predictable patterns. Maybe  a collective choice to spend on more storage would improve flexibility and access, but would it be worth the ongoing cost? Each microgrid might decide for themselves.

I guess the first thing I personally would do is ruthlessly eliminate waste and inessential loads. Find new ways to do things without electricity, or don't do them at all.

Another big one for each house would be water use. In rural areas, everyone is on a well here in the midwest, with an electrical pump at the bottom of it. Increase or create aboveground storage? Have an extra large pressure tank and even a cistern? What about homes in an urban neighborhood on city water? How will local utilities power themselves and still provide sufficient water? I can see water bills going up. Less and very quick showers would become the norm.

Home heating is a whole other can of worms I won't go in to right  now.

Next would be learning how to time shift, and how to get household chores arranged so they are prepped and ready to go as soon as a sunny day occurs. Lots to think about.

Electricity will become very expensive, and thus husbanded like the unique resource it is. Could this concept even be affordable?

But at least we'd still have it for a while.
