Decent Math Encounters Reality

Last week, I put together this raised bed for Andreas, Sandra and Ted.  It's made of cedar construction treated with linseed-oil.  Take a look.  Also note the micro-irrigation tubing sticking out in preparation for filling with soil and compost

The bed is 8x4x2.5ft.  If you multiply that out you get 32ft x 2.5ft or 80 cubic feet.  My truck bed holds a cubic yard, i.e., 27 cubic feet, so you could reasonably calculate that it would take less than three truck loads of substance to fill the raised bed  (72/27 = 2.9).  Such was my calculation when I began filling the raised bed.

However, the soil I filled the bed with was magic soil, or so it seems because in order to fill the bed, I had to shovel in four truckloads of soil and compost.  That's approximately 108 cubic feet.  

Try to wrap your mind around that.  And in the meantime, you can rid your mind of the notion that mathematics adequately describes the world around us.

Why Can I Eat Bread in France, but not the USA?

Updated 10/31/2017 as the National Organic Standards Board meets in Jacksonville, FL. This may well be the most important thing you read this year for your health. (Originally written in 2015 while I was traveling-- and eating bread-- with my wife in France.)

I've got a food riddle for you from Paris, France: Why can I eat bread over here when it makes me sick at home?

I'll share my best guess in a minute, but first, a little personal background.

Since my senior year of high school, I've not been able to eat much bread at all. For five years, I was severely hypoglycemic, and everything I ate had to have more protein than carbohydrates. That meant, in effect, that I spent my years of college beer-less and eating lots of salad with meat on top. I ate tons of vegetables, very little fruit, basically no carbohydrates to speak of, meat, nuts, eggs, and cheese. If I accidentally ate, say, meat loaf that was, unbeknownst to me, made with bread in it, I'd spend the next 2-3 da…

Man in Overalls - The Valley of Food & Ag Startups: Warren Wilson College

If you're interested in tech, pay attention to Silicon Valley. If you're interested in food and agriculture, Swannnoa Valley, more specifically Warren Wilson College, is the place to keep on your radar.
I'm an alum and proud of it, class of 2008. I studied community organizing, wrote a 140 page thesis about social movements as my capstone.
It's a work college, one of seven in the country. Think universal work-study, so in addition to whatever one's academic track, students are also working in the cafeteria, the library, admissions, as carpenters, lock smiths, lab techs, and-- per the agricultural legacy of Warren Wilson-- as row crop, animal, and vegetable farmers, gardeners, and edible landscapers.  Personally, I worked on the electric crew and then on the landscape crew where I led the edible landscape sub-crew in managing a 1-acre edible (Permaculture) landscape around the "Ecodorm."

Per the "triad" of Warren Wilson's educational system,…

Man in Overalls - Growing Great Soil

Good soil will basically grow your groceries for you, but how do you build great soil? 
The answer is that there are two options: a quick & easy way and a DIY, hard(er) way. 

So we're on the same page, I'm continuing my #GrowYourGroceries The Easy Way series by digging into the how-tos of growing great soil. These stories and techniques will likely make the most sense after reading Geeking on Good Soil, my last update. (I outlined where I was headed in The Big Picture.)

As I was saying, the easy way to build a great soil is to fill raised beds with a terrific compost-based soil mix like my Magic Mix to jump start your food garden productivity from year one. From there, seasonally, you simply top-dress each season before planting with another few inches of compost-based soil mix. This is how I manage my own food garden and those of my customers. Why? Because at the root of things, I'm a lazy food gardener, and long ago I decided to embrace it. 😎

But if you're not in th…
