Planes had to fly 15,000′ to get above it. 2) The growth of pumping capacity Americans in all regions of the country will be driven to increasingly short-term, exploitative desperation. We are a farming family and began to study it more intensely about three years ago. Be Truthful. There is also the more global question of desertification, described by National Geographic in “Desertification, explained“: While land degradation has occurred throughout history, the pace has accelerated, reaching 30 to 35 times the historical rate, according to the United Nations. In the Dust Bowl, farmers lost 480 tons per acre. Here are some figures on the topsoil — yes, I finally got round to it! . “There is also the more global question of desertification, described by National Geographic in “Desertification, explained“. © 2020 American Association for the Advancement of Science. Keep it Clean. From space, an instrument called MODIS does the same job, looking at how much light reflected from the surface is similarly blocked by particles. As with Covid, nature may have been generous enough to give us a trial run with a relatively easy plague. The first part documents the regeneration of the Loess Plateau in China. https://en.wikipedia.org/wiki/Buffalo_Commons. From the ground, the IMPROVE monitoring network is run by several federal agencies and measures the amount of particulate matter in the air at sites, including national parks, around the country. There are many American farmer and scientist videos. a shutoff valve- tile systems never have valves, based on my experience). From what I have read, that was part of the whole point of ammonium nitrate as “fertilizer” to begin with. That is what I remember reading anyway. Furthermore, nutrient loading from agricultural runoff is the prime culprit in the formation of oceanic dead zones, such as in the Gulf of Mexico, as agricultural runoff/effluent is “lightly” regulated. Notifications from this discussion will be disabled. I had to truncate the post, sadly, and may return to this topic. Even coyotes were subdued at night, seemingly cowed by the spookyness of the place. The focus of the study… was to quantify how much the amount of dust in the atmosphere over the Great Plains had changed in recent decades. There were Congressional hearings taking pace about the soil problem in the west when to their disbelief the skies darkened with the clouds of that very same dust from the west. Have a look at what Wes Jackson et al have been doing at the Land Institute, on Water Well Rd. As an aquifer is drawn down, water quality goes to hell before the water runs out, assuming that the cost of pumping associated with deeper water levels doesn’t get prohibitive first. You know how silver and copper are great for hospital stuff because they do charge funny business that rips apart organic molecules? https://www.amazingcarbon.com/ is her page of her papers. There are just far too many people on Earth using its resources well beyond its carrying capacity. Exports sailed the world. On Pasture explains the sensors used in the GRL study, and zeroes in on the rising dust in “Is a Second Dust Bowl on Its Way?”. https://www.youtube.com/watch?v=qXbvpBI08vs&feature=youtu.be. Eyes on the prize! But immediately switching over to an ag system based on root structure will retain what’s left. They said, “This is not the direction that we want to promote,” or something to that effect. Please log in, or sign up for a new account and purchase a subscription to continue reading. I am ONLY a lay amateur science buff. You are comparing what has happened with what might happen in the future. What would the pedologist say? However, one item that has always stuck with me is actually an assessment I heard on public radio a few years ago. Predictably, there are labs trying to figure out how to market the biochar component for max profit, but there also seems to be broader interest for sustainable agriculture, with considerations for climate change. In 2000, some of it is still sterile and blowing. Indeed, the differences between developing nations and the U.S. are in truth a distinction with an ever diminishing difference. Here is a bunch of aerial photos of removed-mountaintop minesites after the mountaintop removal mining has happened. I don’t have the time to watch a video of unknown provenance on a whim, and your asking me to do so amount to assigning tasks. Thanks for this view. I suspect many if not most readers feel the same. NASA’s Earth Observatory, “Temporary Drought or Permanent Desert?” adds an important element to the discussion: The United Nations’ official definition says desertification is land degradation in typically dry areas resulting from various factors, including climatic variations and human activities. Earlier this month, a storm front swept across the Great Plains of the United States, plowing up a wall of dust that could be seen from space, stretching from eastern Colorado into Nebraska and Kansas. Now factor in the remoteness & distance to markets. LOL. From 1925 to 1930, over five million acres of unfarmed land were plowed; 1931 was a record year for crops. I don’t see any reason to think that the amount of airborne soil would compound steadily every year – if anything it would tend to reduce as there is less soil to transport. After thorough testing of the sterile grinded bits for total mineral content, industrial quantities of any other mineral-sourcing rock needed to create nutri-mineral balance could be brought and mixed in. The same National Geographic that sold out to their chemical company sponsors and heartily endorsed the safety, efficacy and desirability of GMOs? Unfortunately, the overproduction of wheat decimated the natural drought-resistant grasses and fertile topsoil, and left unused fields bare. “So while the agriculture industry is absolutely important, we need to think more carefully about where and how we plant.”. The following year, farmers slaughtered well over six million pigs to reduce supply and increase prices. 3 weeks horsebacking in New Mexico will give you a feel of the enormity. In the 19th Century, the feds told the advancing white pioneers that the “rains followed the plows,” which led them to tear up thousands of acres of land and, ultimately, leave it prone for disaster. Be Proactive. But sea water isn’t fresh water. My family has been here since before the Civil War and while I probably will have to move for work reasons again eventually, having been under these big skies the past year while the world has gone literally and functionally crazy has been a slight benefit. I am just an amateur science buff. I was thinking of limiting the experiment to the flat scar lands because only they would be non-subject to erosion on top of all the other problems. “We can’t make changes to the earth surface without some kind of consequence just as we can’t burn fossil fuels without consequences,” says Andy Lambert, lead author of the study and a recent U graduate. https://regenerationinternational.org/resources/, Dr Elaine Ingham https://www.soilfoodweb.com/ is also well known, but more advanced into microbiology than I want to follow.
