Mark gave a presentation last fall and handed a lot of stuff out. Today, he emailed me this stuff and gave me permission to post it here.

And here is the presentation:

Hello Paul,

I too am not able to download the handouts. Could the problem be the spaces in the file name when uploading or downloading the files? I tried to download by changing the spaces in the file name to % to try and download but that didn't work. I also tried the "%25" space substitution and "%2520" space substitution but neither worked.

Thanks for uploading the video!

Fascinating video, but it stops at 3:19, buffers and buffers and never comes back. I hope you can fix that.

I think this is an issue on your side. It works fine here.

I'm not sure if this is the place to ask questions about the video but I was wondering about the part where Mark mentions the dangers of terracing. I'm not sure I understood what he was saying but it sounded like he was warning that terracing can create a damming effect which could destroy the hydrology and collapse the terrace system through waterlogging. If this happens, what is the implication? Terracing is bad? Only certain types of terracing should be used? If so, what kind? Only certain slope grades should be terraced? If so, what grades? Only areas with a certain rainfall amount should be terraced? If so, what rainfall amount? Does anyone have any thoughts on this?
If this is not the place to ask this question, could someone direct me to the correct forum? Thanks.

Was able to watch the whole thing.

FANTASTIC!

Such a simple, clear explanation of basic principles, practical and relatively easily implemented.

Enormously useful!!! Now that I get the process of how the soil is healed, I can better choose which specific technique to use where and when.

Now I understand what I have seen with my own eyes in how plants respond to various techniques I have used....conditions at the start, materials used, time frames, etc.

So I can go beyond rigid adherence to one system or another, know where to focus my efforts. I can proceed with more confidence and have more peace of mind as I patiently await the inevitable results.

I am doing an enormous amount of work on these issues, putting in a 1/4 acre Permaculture Food Forest in SE Portland, Oregon, and this makes such a huge difference.

LOVE IT!!! Thank you so very much to all involved. I can't thank you enough.

This is the right place to ask the question about Mark's statement.

The way I understood it, he was saying that terraces that are not properly built are the problem.

Thank you Adrien for the response. I would have been quite shocked if Mark was opposed to all terracing. I'm sure there must be many ways to build a terrace improperly. Would you have a guess as to what kind of improperly built terrace Mark might have been referring? That is, a terrace that might get waterlogged or interfere with the hydrologic cycle. I am interested because I plan to build many terraces on at least 50 acres and want to avoid building them improperly. Thanks.

I am really not an expert in that field. I think in sepp holzer's Permaculture, Sepp describes how to build them, but I don't have the book with me right now.

Thanks Adrien, I will look at that book again. Thanks for all the work you do.

Richard,
I once took a course in soil conservation at university where we looked at soil practices such as terracing, gully restoration an, contour farming etc. It was a long time ago but this was the text book we used (I still have it), it contains some useful info on terracing, and loads of interesting stuff for permies into earthworks or dealing with steep land (unlike me):

http://www.amazon.com/Soil-Conservation-Norman-Hudson/dp/0813823722

I'll have a look around in my old notes and PM you if I find any useful stuff?

Greetings
Dave

Thank you Dave,

I followed your link and ordered the book! Amazon wanted $441.00 U.S. for it but I ordered it through a reseller for $14.95! Looks like a valuable reference book. Yes, please let me know if you find any more useful stuff. Thanks again.

Wow that was a fast decision to make! At least I'm glad you didn't go for the first price you saw, who pays that much for a book?!?
In the meantime, the only document on the computer I have left from that era is a powerpoint presentation on terracing, hereby attached. All the rest is paper notes and handouts, so not likely to be scanned in or uploaded any time soon! The presentation is a bit light in terms of content but maybe interesting all the same, bear in mind I was 20 and that at the time I could hardly fit it onto a floppy disc!

Curious to know where and what you're terracing with.

Sorry it won't let me attach a .ppt file, PM me your email if you're interested

I had another question about soil health, in particular in a suburban lawn setting. Mark mentions the importance of air in the soil, and even mentioned three different ways of achieving that. What about core aeration (where you end up with all those little lumps of dirt all over the place)? Is that effective, and is it good (or will it cause some other harm)?

Thanks!

A late addition to the terracing issue.

I think Mark is not just critical of improperly built terraces. I think he's saying that whenever you take out a chunk on the side of a slope, and especially when you fortify the vertical part you've created, you are damming up water above, causing the soil there to be at risk of waterlogging and landslides. I'm sure there are ways to mitigate this problem, e.g. by creating opportunities for drainage, but it is a pretty fundamental isssue. If your slope is steep and your climate is wet, this is a significant risk.
