Thanks for reading this email. If you don't enjoy it, feel free to unsubscribe. I won't bother you again. No hard feelings. SCIENCEDry sandy soil can actively refuse water. Not drain it. Refuse it. The water beads up and runs off, or finds one channel and pours straight down it while the soil an inch away stays bone dry. You water, and it is still dry. As plant material breaks down, waxy compounds from plants and microbes coat the outside of the sand grains. Sand has so little surface area that a small amount of that coating goes a long way. A raincoat on every grain. It is worst when the soil is driest, which is exactly when you need water to go in. From a distance this looks identical to ordinary fast drainage. Wilted plants, dry ground. But one is water that got in and left, and the other is water that never got in, and they do not have the same fix. The test costs nothing and takes a minute. Scrape the top few millimeters off a dry patch to get a flat surface. Put one drop of rainwater or distilled water on it and count. Under five seconds, your soil is fine. Five seconds to a minute, slightly repellent. One to ten minutes, strongly repellent. Still sitting after an hour, and yes that happens. Test several spots, because repellency comes in patches. If it sits there, you have been watering soil that was never taking it. BUSINESSTroy is seven years in on the coast of Maine. Two kids. Grosses around $150,000. Sells everything he grows. Works midnight shifts. He described the farm to me as something he can't quit on. Sit with that phrasing for a second. Not that he loves it and wants to keep building it. Not that it is the best use of his skills and his time. He can't quit on it. That is the language of a test you are passing, not a business you are running. And it has consequences that show up directly in the books. When the work becomes proof of your worth, you stop being able to make ordinary decisions about it. You can't delegate, because handing off a job feels like handing away a piece of yourself. You can't cut the enterprise that isn't working, because it was part of the vision. You can't step back, because stepping back feels like admitting you weren't good enough. Every one of those is a business decision you are no longer free to make. Here is the one that got me. Troy used to carve wooden spoons and bowls by hand and sell them at market. They sold out immediately. A real part of the business. Gone. It fell to the side, in his words. A product with proven demand and no competition got dropped, while the harder, thinner parts of the operation stayed. Not because the numbers said so. Because the spoons weren't proving anything. I did the same thing with a different hobby horse. When my conference business failed in 2012, I concluded I hadn't worked hard enough. The other possibility, that effort in does not reliably equal success out, never got considered. I just kept going for years. Try this on whatever you spend the most time on. If you finished it and simply stopped, would you be okay? If yes, it is work. If no, if you need it running to feel like yourself, then the farm is doing a second job you never hired it for. And if you are working hard and it never feels like enough, that may not be a productivity problem at all. What Troy worked out about running two lives off the same back door, and the one thing I have started doing that the engine hates: OWNER'S LIFETeaching my kids, I notice the same thing over and over. When they don't know the answer, they don't want to work it out. They want to be handed it. And if they can't be handed it, they want the shortest possible route to it. For a while I filed that under kid behavior. It isn't. Adults do exactly the same thing, we just dress it up better. We call it best practices. Proven systems. The right way to do it. The appeal is obvious. Somebody already paid for that mistake, so why pay again? What that skips is the part where you actually learn something. The mistake is not the toll you pay on the way to the answer. The mistake is the thing that sends you looking in the first place. And on that trip you pick up a hundred things nobody could have handed you, because they aren't answers. They're judgment. You learn why the right way is right, which is the only way to know when it stops being right. On your ground, in your market, in a year that doesn't look like the last one. There's a second problem with wanting the answer. Most of the time there isn't one. Not a clean one. There's what worked for somebody, on their soil, with their customers, at their scale, in their weather. Handed to you with the context quietly stripped off. Your neighbor's bed spacing is an answer. Why it works on his ground is the thing you actually needed. Next time you catch yourself hunting for the right way to do something, check which one you're after. Learning it and skipping it feel the same when you start. They don't feel the same in year three. - Diego |

SCIENCE There is a moisture point where soil stops crumbling and starts smearing. Engineers call it the plastic limit. Past it, you are not breaking soil apart anymore. You are molding it, like Play-Doh. The air gets squeezed out and the surfaces get pressed closed. That last part is the damage. The gaps don't get smaller. They get sealed. And gaps are the entire ask from a root. A root is not shoving its way through soil. It is looking for an opening roughly as wide as its own tip. In one...
SCIENCE Loam is the soil everybody tells you to want. It is not the best soil at holding water. On the USDA tables, three textures beat it. One of them is clay loam, which is roughly what half of you are trying to get rid of. The top one is silt loam. The reason is a distinction nobody makes at the garden center. Total water held is not the same as water your plants can actually pull back out. Clay holds enormous amounts of water and grips so much of it that it can't release it. All that...
SCIENCE Before you spend a dollar fixing clay, find out whether clay is your problem. Texture is what the mineral part of your soil is made of. Sand, silt and clay in some ratio. You can change it. The cost is absurd on ground you are already farming. Structure is how those particles are stuck together. Your management moves that one. A lot of what gets called a clay problem is a structure problem wearing a clay costume. Two spadefuls will tell you which one you are dealing with. Ten minutes,...
