Nutrition
Comments (13)Anyone eating corn for nutrition...be it now or 100 years ago...is "doing nutrition wrong." It's never been a nutrient-dense food as far as vitamins go, though it does have some nutrient quality in the way of carbs and vitamin B. It's a minor, yet noticeable, vitamin A+C contributor to nutrition. Also, the notion that our lines of supersweet corn came from radioactive/mutating experiments is grossly off the mark. Most come from lines of natural selection and breeding by John Laughnan at UI working with a gene most other breeders wouldn't touch. It is a total bastardization of John Laughnan's work (who, unlike what was stated WAS a plant breeder and botanist at U.Illinois) to claim he was by-chance poking around human-mutated "radioactive" corn to make supersweets happen. His work on the sh2 gene is one of the most important breeding pushes in the line of sweet corn. His crossses with Golden Cross Bantam (not to be confused with Golden Bantam which has been around since the early 1900s) for enhanced sweetness are his babies and it was developed with much resistance from his peers because they didn't see the value of the sh2 gene, which usually caused undesirable shrived kernels (because of less starch content and higher sugar content). One of his crosses, Illini Chief, is still sold by Burpee (who developed the initial Golden Bantam, btw), Shumway, and a few other seed sellers over 50 years after it first hit the market. Until his research into this gene it was believed to be a gene that led to inferior product rather than a line worth investigating. When his work led to incorporating the sh2 gene into corn which can produce full/plump kernel cobs, people paid attention. Btw, this was not a 1959 discovery, as stated by the author...he published his initial work on the sh2 gene as a breeding gene worth investigating in 1953 and his work started years earlier. I have no idea where he/she got her information on Dr. Laughnan from, but he/she should check that source again. John Laughnan is a bit of a hero to many in the breeding industry. This kinda pokes me wrong a bit personally to see his name/work trashed like this...and his work cheapened to being some fool who stumbled upon his discovery. It's so off the mark it's insulting. He was far ahead of his time given that supersweets took another 1-2 decades to even become popular in breeding. His work with developing the sh2 gene from a shriveled-kernel "undesirable" gene into a farmer/consumer market changer ranks right up there with Lamborn and Parker's work with the sugar snap pea that led to the "modern" sugar snap we've enjoyed since the 1970s. It was a game changer that went ignored for far too long given the long cultivation history of the plant(s).

Comments (13)Oh, canning tomatoes. Yes, I have canned my tomatoes. I hate canning tomatoes. Even with a pressure canner, the kitchen gets so hot that I have to turn on the air conditioner; it uses up a tank of the propane we fuel the stove with in half the time the tank usually lasts; it's a lot of work; and what you end up with is canned tomatoes that taste like -- guess what? -- canned tomatoes. Other people may taste a difference, but I can't. After I ended up in tears on the kitchen floor one summer, pregnant, sweaty, coated with tomato goo, and needing to be rescued by Mr. Alfie, I stopped canning and started freezing. Blanch, peel, cut up, seed (maybe), zip-loc, freeze. The only problem with this is that we inherited a side-by-side refrigerator/freezer, and so by the end of the summer, it's prudent to wear steel-toed boots when you open the freezer door. I've made green tomato chutney, green tomato pickle, green tomato chowchow, green tomato mincemeat, and green tomato and apple pie, and my own personal conclusion on the subject of green tomatoes, applying only to the garden of me, Alfie, is -- leave 'em in the garden to compost....See MoreNPK of compost
Comments (74)I agree with gardengal 48 and Jolj. And so do most university agriculture experts, extension offices, and documented and verifiable scientific studies. I am taking a course on this now. Oh, and to the comments about you can't have too much compost...well, that is inaccurate. One contributor said it is balance. I agree, but to know what the balance is or what is needed to maintain that balance requires testing. Most of us can't afford a complete soil test (it isn't just about NPK), so we guess as best we can. Sure, there are some NPK and other nutritional elements to compost, but compost is still considered an amendment, not a fertilizer. Part of it is WHEN or HOW do those nutrients become available to the plants. Anyway, this is several years after the original post, so I hope the poster is still gardening and is successful. :)...See MoreHydroponic Hops
Comments (63)I plan on all three. The latter will take some extra time and funding, though. I am currently deciding whether to use Aeroponics or Hydroponics for it. I have heard that Aero is slightly better but Hydro is more reliable. I live in Chicago so if there's a power outage like the ones from the Tornadoes the other day, then I don't want the plants to die. Aeroponics is often very hard to assemble individual parts into a well-working system, and the individual parts can be expensive as well. Also, the fine-spray emitters will instantly clog if you try to use anything except high quality hydroponic fertilizers (no organics). Of all the hydroponics growing systems, this is the most difficult to master and the most tempermental. Ph changes and nutrient imbalances occur more quickly because of the increased absorbtion rates and high levels of oxygenation. Furthermore, with no grow media to protect the roots, the plants react negatively to these changes much more quickly....See Morevalerie_ru
