Apparently I can't keep up with myself. Here is a backlog of recent videos on everything from rawhide to roads.
The difference between the different sections of the leek bed are even more obvious now, confirming more what I observed this summer, which is that the soil with charcoal (biochar) has what is generally referred to as heart. That is to say it has staying power and isn't easily used up without regular additions of fertilizer. I've been very negligent with this leek bed and it really shows on the control end with no charcoal, but not much on the 10% char end. The 5% section is better than half way between the two others, but there is an obvious difference except that within one foot of the 10% section, the plants are nearly indistinguishable from most of the rest of the 10% section. The very end of the 10% section drops off in size, but that may be due to the shape, of the bed, which is pointed on the end. Also, many gardeners will have observed that plants tend to do less well on the ends of beds. If you took the difference between the control end and the 10% end as at least 600% difference, that could be interpreted as the 10% char end making 600% better use added amendments. That is a sloppy interpretation and doesn't take into account all possible factors, but it's still impressive and probably on the low side if anything. The leek seed from this project will be ready in the fall for planting about this time next year.
ROAD SERIES PRIMER
This one is a quick primer for what will be a series on the design of graveled roads based on what I learned and have observed building mine, as well as paying attention to other unpaved roads and what happens to them in various circumstances. It will have to potential to save a lot of people, time, money, unpleasant driving conditions, all while saving resources ultimately and keeping sediment out of stream beds. In the meantime, you can download the handbook for forest and ranch roads for free here. It is a dry read, but very worth putting to use if unpaved roads are a regular part of your life. http://www.pacificwatershed.com/sites/default/files/roadsenglishbookapril2015b_0.pdf
RAWHIDE HANDLE BRACE FINAL
This is the final part of the rawhide axe handle brace. As usual for me, this series wasn't just about making this one tweak, but about rawhide and sinew and hide glue and context and related stuff.
