The Fraud of No-Till
Intro No-till is a type of farming which rose to the surface about like the carbon dioxide fraud. It's a charlatan's paradiseeasier to lie about than climate change, because agriculture has infinite variables influenced by humans. So charlatans promote no-till simply because it is the thing to do. It's a lot easier to be right when objective reality vaporizes into words on a page. The definition of no-till is that no machinery touches the ground except the planter. You plant right into the stubble from the year before. The primary benefit is supposed to be a reduction in erosion, and infinite trivial comparisons always show something better about no-till, except there is no objective way to define better. Better is in the eye of the beholder, and nowhere more than no-till. Claims of carbon sequestration through no-till are shown to be false through testing, and the whole concept is absurd. If carbon is not escaping the soil, it must be accumulating. How much is supposed to accumulate and for how long? It normally doesn't; and it shouldn't. The Erosion Fraud When you search no-till on Google, most of the articles are on problems that need to be overcome with no-till. One of the problems is that water erosion creates gullies with no-till, because the ground is not "smoothed" each year. Planting grassed waterways is one of the answers, except small gullies tend to permeate a field. No-till promotes erosion by not mixing the surface. Soil apart for organic matter erodes more than soil mixed with organic matter. Decaying organic matter improves soil texture, while nondecayed organic matter does not. Surely, research has settled this matter. No, the claim that no-till reduces erosion is rattled off the top of someone's head apart from research. Erosion is not easy to research beyond obvious extremes. And the whole problem with researching agriculture is that there are no clear references to compare to. Researchers in agriculture, particularly with no-till, compare to something which gives them the result that they want. There are no stable references or "controls" as laboratory scientists use for making comparisons. No-till is compared to black ground, as if molderboard plowing were the alternative. Plowing turns the ground over exposing microbes and organic matter to the sun and wind, which sterilizes the ground and leaves a dry powder on top to blow around. Compared to Incompetence. The promoters of no-till list the supposed benefits in comparison to bad alternatives, which are the worst case scenarios which should never exist. Compared to best practices, no-till is a ground killer. It's like putting training wheels on a kiddy bicycle. If a kid can't keep a bicycle upright, then training wheels might be an improvement. But should everyone use them? No-till would only be an improvement if everything were done the worst way possible. Agriculture has so many variables that I can't say there are no conditions where no-till would not be an improvement all the time over any other practice. But if so, it would only apply to an extremely small set of conditions. It is obvious that for all normal conditions, no-till is bad for the ground and bad for farmers. Compared to Tillage No-till is compared in a generalized way to tillage, as if tilling the ground were the ruination of agriculture. Tilling the ground is the most important thing farmers can do. Proper tillage does not leave the surface black, as the no-tillers claim. The best, and usual, way to till the ground nowdays is to sink chisels or sweeps in a good distance to loosen up the soil without burying the stubble. The stubble needs to be knocked down and near the surface, with some buried and some on top. If the stubble is real heavy, like high yielding corn, it needs to be knocked down with something like a disc. But still, deep cultivation is extremely valuable in opening up the ground. Deep cultivation does some very critical things. It allows the roots to go down easier, which is particularly critical with heavy soils, where roots will sit near the surface otherwise. To use no-till on heavy soils will totally destroy a crop by preventing roots from going down through the hard ground. Even shallow cultivation damages the crop in hard ground due to inability of roots to penetrate. Yet no-till is promoted for all types of soil as if there were some universal and invariable benefit. Another important result of deep cultivation is to allow oxygen and moisture to penetrate. Oxygen is needed for decay. If refuse is buried over sealed ground, it will sit for years or decades without decaying. The refuse will harbor weed seeds with it, and they will keep germinating and coming up for many years. Crazies assume it is good to have refuse on and under the ground. Farmers used to do everything possible to get refuse to decay. Now they let quacks tell them there is something good about undecayed refuse. Undecayed refuse interferes with every element of agriculture, and there is nothing good about it. It does not stop erosion. Erosion occurs under refuse and around it. Only decaying organic matter integrates into the ground suitably for reducing erosion. Farmers with heavy refuse, as in the corn belt, who practice no-till have accumulations of undecayed refuse which is destroying their ground and their ability to farm it. Yet they allow charlatans to tell them there is something good about it. It's like blood letting. It is said that George Washington was killed by blood letting. People have a tendency to let frauds tell them things which don't look right, even when they can see a lot wrong about it. My Background I've lived on a farm most of my life, and still do, though I no longer farm. I started college studying agriculture before switching majors to microbiology. My last year in high school (1963), I paid for a new car with a forty acre oat crop by chiseling the ground and conditioning it properly. So I integrate a lot of science with agricultural experience and observations. I notice that farmers often lack scientific understanding which would benefit them. What no-till shows is that even the ones who get a lot of advanced education can get things really screwed up, because education is focused on technology which is exploited by charlatans at the expense of the unwary.
