Good luck with that. you quote the whole thing for a one line reply? oh, ok, Billy, i see your comprehension is down, read again where i said i composted my reply off-line. i have a very slow connection, i do not watch tv or load audio via internet unless it's the rare thing i want to wait hours to accomplish, usually i cannot tie up the phone line for that length of time. i'm mostly here to converse and read about gardening, i'll try to have fun in the process. most of what you write in reply i am aware of and actually agree with in some parts, if you'd read it you'd see. yet there are large gaps even in that time will show. poking at them is just the way i am. now can you tell me what happened to the art of general shooting the shit? it sure isn't about quoting links back and forth. good day, songbird |

This is called "Modeling Behavior". The Omnivore's Dilemma: A Natural History of Four Meals by Michael Pollan p.45 - 46 http://www.amazon.com/Omnivores-Dile...ls/dp/01430385 83/ref=pd_bbs_1?ie=UTF8&s=books&qid=1206815576&sr=1-1 The reason Greene County is no longer green for half the year is because the farmer who can buy synthetic fertility no longer needs cover crops to capture a whole year's worth of sunlight he has plugged himself into a new source of energy. When you add together the natural gas in the fertilizer to the fossil fuels it takes to make the pesticides, drive the tractors, and harvest, dry, and transport the corn, you find that every bushel of industrial corn requires the equivalent of between a quarter and a third of a gallon of oil to grow it‹or around fifty gallons of oil per acre of corn. (Some estimates are much higher.) Put another way, it takes more than a calorie of fossil fuel energy to produce a calorie of food; before the advent of chemical fertilizer the Naylor farm produced more than two calories of food energy for every calorie of energy invested. From the standpoint of industrial efficiency, it's too bad we can't simply drink the petroleum directly. and the other question for Billy is how does organic gardening sequester carbon dioxide? improving soil is good, mixing organic stuff in and making all the various critters happy is great, but that is nutrient cycling not carbon sequestration... we need carbon sequestration at this point. can we get that via organic gardening methods at present? Only in terms of bio-mass, unless you include "terra preta", and its charcoal. Teaming with Microbes: A Gardener's Guide to the Soil Food Web Jeff Lowenfels and Wayne Lewis Ch.1, second paragraph. http://www.amazon.com/Teaming-Microb.../dp/0881927775 /ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1206815176&sr= 1-1 In addition to all the living organisms you can see in garden soils (for example, there are up to 50 earthworms in a square foot [0.09 square meters] of good soil), there is a whole world of soil organisms that you cannot see unless you use sophisticated and expensive optics. Only then do the tiny, microscopic organisms‹bacteria, fungi, protozoa, nematodes‹appear, and in numbers that are nothing less than staggering. A mere teaspoon of good garden soil, as measured by microbial geneticists, contains a billion invisible bacteria, several yards of equally invisible fungal hyphae, several thousand protozoa, and a few dozen nematodes. ---- Gaia's Garden, Second Edition: A Guide To Home-Scale Permaculture (Paperback) by Toby Hemenway p.78 http://www.amazon.com/Gaias-Garden-S...ulture/dp/1603 580298/ref=sr_1_1?ie=UTF8&s=books&qid=1271266976&sr=1-1 Like most living things, leaves are made primarily of carbon-containing compounds: sugars, proteins, starches, and many other organic molecules. When soil creatures eat these compounds, some of the carbon becomes part of the consumer, as cell membrane, wing case, eyeball, or the like. And some of the carbon is released as a gas: carbon dioxide, or CO, (our breath contains carbon dioxide for the same reason). Soil organisms consume the other elements that make up the leaf, too, such as nitrogen, calcium, phosphorus, and all the rest, but most of those are reincorporated into solid matter‹organism or bug manure‹and remain earthbound. A substantial portion of the carbon, however, puffs into the atmosphere as carbon dioxide. This means that, in decomposing matter, the ratio of carbon to the other elements is decreasing; carbon drifts into the air, but most nitrogen, for example, stays behind. The carbon-to-nitrogen ratio decreases. (Compost enthusiasts will recognize this C:N ratio as a critical element of a good compost pile.) In decomposition, carbon levels drop quickly, while the amounts of the other elements in our decomposing leaf stay roughly the same. 1491: New Revelations of the Americas Before Columbus : Charles C. Mann http://www.amazon.com/1491-Revelatio...mbus/dp/140003 2059/ref=sr_1_1?ie=UTF8&s=books&qid=1269536235&sr=1-1 According to a recent study led by Dirse Kern, of the Museu Goeldi in Belem, terra preta is "not associated with a particular parent soil type or environmental condition," suggesting that it was not produced by natural processes. Another clue to its human origin is the broken ceramics with which it is usually mixed. "They practiced agriculture here for centuries," Glaser told me. "But instead of destroying the soil, they improved it, and that is something we don't know how to do today" in tropical soils. As a rule, terra preta has more "plant-available" phosphorus, calcium, sulfur, and nitrogen than is common in the rain forest; it also has much more organic matter, better retains moisture and nutrients, and is not rapidly exhausted by agricultural use when managed well. The key to terra preta's long-term fertility, Glaser says, is charcoal: terra preta contains up to sixty-four times more of it than surrounding red earth. Organic matter "sticks" to charcoal, rather than being washed away or attaching to other, nonavailable compounds. "Over time, it p.346 partly oxidizes, which keeps providing sites for nutrients to bind to." But simply mixing charcoal into the ground is not enough to create terra preta. Because charcoal contains few nutrients, Glaser argued, "high-nutrient inputs‹excrement and waste such as turtle, fish, and animal bones‹are necessary." Special soil microorganisms are also likely to play a role in its persistent fertility, in the view of Janice Thies, a soil ecologist who is part of a Cornell University team studying terra preta. "There are indications that microbial biomass is higher in terra preta than in other forest soils," she told me, which raises the possibility that scientists might be able to create a "package" of charcoal, nutrients, and microfauna that could be used to transform bad tropical soil into terra preta. Despite the charcoal, terra preta is not a by-product of slash-and-burn agriculture. To begin with, slash-and-burn simply does not produce enough charcoal to make terra preta‹the carbon mostly goes into the air in the form of carbon dioxide. Instead, Indians apparently made terra preta by a process that Christoph Steiner, a University of Bayreuth soil scientist, has dubbed "slash-and-char." Instead of completely burning organic matter to ash, ancient farmers burned it incompletely to make charcoal, then stirred the charcoal into the soil. In addition to its benefits to the soil, slash-and-char releases much less carbon into the air than slash-and-burn, which has large potential implications for climate change. Trees store vast amounts of carbon in their trunks, branches, and leaves. When they die or people cut them down, the carbon is usually released into the atmosphere, driving global warming. Experiments by Makoto Ogawa of the Kansai Environmental Engineering Center, near Kyoto, Japan, demonstrated that charcoal retains its carbon in the soil for up to fifty thousand years. i really need to study charcoal production methods... perhaps a solar oven could do it... gotta go look now. songbird -- - Billy "Fascism should more properly be called corporatism because it is the merger of state and corporate power." - Benito Mussolini. http://www.youtube.com/watch?v=Arn3lF5XSUg http://radwisdom.com/essays/this-is-your-brain/ |

Yea I know I can eat the flowers but the light they take takes from some other valued plants. Whew cool down due in 2 days. Nearly 100°F here, yesterday. Not too bad but we haven't acclimated to the heat yet. It's supposed to cool down through the week and then heat up again next week. It's not bad here, but we need to go to the Central Valley, at least once a week, and it gets hot in Sacramento. I finally got to untangling some Swiss chard that was set to germination in April. They were suffering in two, small, germination cell 6-packs. If they all survive, I think I'll be set for Swiss chard for the rest of my life (29 of them). I hope one day to figure out the root garden. It seems that everything is in bloom; radishes, onions, parsnips, celery root, dandelion, borage. Where are the plants supposed to grow? The beets, and a few assorted lettuces are being overwhelmed but the flowers are festive;O) One of my successes for the year is finding a good spot for my lettuce. Up at the top of the yard, against the ivy covered fence, they get morning and mid-day sun, but slip into the shadows for the afternoon. I don't know if this is new to anyone, but I spray the lettuce about 30 min. before I pick it, and it is much crispier. One flowering parsnip is up to 7' now. It is only behind the sunflower because it is leaning on a potato cage. The potatoes are about 5' tall. All in all, not bad for 6 hours of full sun. Yeah, I know, it goeth before the fall, but if you got it, flaunt it;O) Seems like it is taking forever to figure out the best way to garden (a little over 600 sq. ft.) on my little plot of land, on a north facing slope, under trees. Fortunately, the road is just up the hill from me, and allows me sunlight. -- - Billy "Fascism should more properly be called corporatism because it is the merger of state and corporate power." - Benito Mussolini. http://www.youtube.com/watch?v=Arn3lF5XSUg http://www.democracynow.org/2010/6/2...al_crime_scene |

I would be interested to see that too. and the other question for Billy is how does organic gardening sequester carbon dioxide? I am guessing that in the long term organic horticulture has only a mild effect in storage. If you have 10% organic material in your soil you are sequestering more carbon than if you have 1% but it isn't going to be a big carbon sink. Assuming that you can still feed the numbers required. OTOH if you don't use all the chemferts that require energy to manufacture then you are saving some at that end. improving soil is good, mixing organic stuff in and making all the various critters happy is great, but that is nutrient cycling not carbon sequestration... we need carbon sequestration at this point. can we get that via organic gardening methods at present? This can only be answered properly by careful numeric modelling but I don't have a reference for it. My guess is that it won't be so valuable. However if combined with other methods such as forest re-planting and organic pasture management we might make some progress. Regarding the latter, I have seen studies that say that pastures (as opposed to crops) can store significant carbon. To do this you need to grass-feed your animals instead of ripping out the pastures to grow corn to feed them in lots. i really need to study charcoal production methods... perhaps a solar oven could do it... gotta go look now. I think that this would be possible but the big question is what would be the energy cost and financial cost to do it. Regardless of sequestration there is no mid-term solution unless we stop burning fossil fuel at such a rate. We must decide to do this as a species, the limits of availability will make the decision for us in respect of oil quite soon but there is enough coal left to send earth well into the greenhouse if we keep burning it at an increasing rate. And only one long-term solution: stop population growth. David |

My point about organic, before you launched into your unsupported attack on "organic", was the when you get organic, you get more nutrients into your diet. If the enhanced nutrition of "organic" kept you from getting sick, then that would be a good deal wouldn't it? There are an increasing number of studies showing enhanced levels of vitamins in organic produce. More over vitamins have only been recognized for about 100 years. Now there appears to be another class of compounds, flavonols http://en.wikipedia.org/wiki/Flavonoid, which are important to human health. We wondered from your field to point out that part of the benefit of growing organic was to eat healthier foods. Cheap food that lets you get sick isn't such a good deal. Or as they say about Americans, we are over fed and under nourished. but i'm going to return and ask about the two calorie output vs one Billy pulled out of ?

I would be interested to see that too. and the other question for Billy is how does organic gardening sequester carbon dioxide? Also in the 9:46 AM post I am guessing that in the long term organic horticulture has only a mild effect in storage. If you have 10% organic material in your soil you are sequestering more carbon than if you have 1% but it isn't going to be a big carbon sink. Assuming that you can still feed the numbers required. OTOH if you don't use all the chemferts that require energy to manufacture then you are saving some at that end. Long story short, charcoal can last 50,000 years, and it can have the added benefit of improving the fertility of the soil. -- - Billy "Fascism should more properly be called corporatism because it is the merger of state and corporate power." - Benito Mussolini. http://www.youtube.com/watch?v=Arn3lF5XSUg http://www.democracynow.org/2010/6/2...al_crime_scene |

On Mon, 28 Jun 2010 18:26:01 -0700, against all advice, something
compelled Billy , to say: There are an increasing number of studies showing enhanced levels of vitamins in organic produce. Cite three. Thank you. |

You probably already know that nitrogen production uses natural gas as its feedstock... Yes. The Haber process produces greenhouse gases as a by-product and it is a factor in the overall energy economy as that natural gas could be used (for example) to generate electric power or to run cars. The process can also use other hydrocarbons or none at all. The haber process can be run from hydrogen produced electrolytically which doesn't generate GHG if you get your electricity from renewable sources but that would increase the price of fertiliser at current renewable electricity prices.

When you add together the natural gas in the fertilizer to the fossil fuels it takes to make the pesticides, drive the tractors, and harvest, dry, and transport the corn, you find that every bushel of industrial corn requires the equivalent of between a quarter and a third of a gallon of oil to grow it gallons of oil per acre of corn. (Some estimates are much higher.) Put another way, it takes more than a calorie of fossil fuel energy to produce a calorie of food; before the advent of chemical fertilizer the Naylor farm produced more than two calories of food energy for every calorie of energy invested. you need to mark the citations quotes differently from your own words. i cannot tell if the following remark is yours or the "authority" you are citing... From the standpoint of industrial efficiency, it's too bad we can't simply drink the petroleum directly. not an EPA approved use of that material! i am shocked at you Billywonkanobi. ( ) and the other question for Billy is how does organic gardening sequester carbon dioxide? improving soil is good, mixing organic stuff in and making all the various critters happy is great, but that is nutrient cycling not carbon sequestration... we need carbon sequestration at this point. can we get that via organic gardening methods at present? Only in terms of bio-mass, unless you include "terra preta", and its charcoal. *ding ding!* Teaming with Microbes: A Gardener's Guide to the Soil Food Web Jeff Lowenfels and Wayne Lewis Ch.1, second paragraph. http://www.amazon.com/Teaming-Microb.../dp/0881927775 /ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1206815176&sr= 1-1 In addition to all the living organisms you can see in garden soils (for example, there are up to 50 earthworms in a square foot [0.09 square meters] of good soil), there is a whole world of soil organisms that you cannot see unless you use sophisticated and expensive optics. Only then do the tiny, microscopic organisms nematodes A mere teaspoon of good garden soil, as measured by microbial geneticists, contains a billion invisible bacteria, several yards of equally invisible fungal hyphae, several thousand protozoa, and a few dozen nematodes. do you know that there are places where earth worms are not native and they are considered alien invasive species? have you studied any forest floor ecologies?

When they die or people cut them down, the carbon is usually released into the atmosphere, driving global warming. Experiments by Makoto Ogawa of the Kansai Environmental Engineering Center, near Kyoto, Japan, demonstrated that charcoal retains its carbon in the soil for up to fifty thousand years. ah yes, that's a helpful idea and i suspect people will be amending away. since it is a lighter material i may include some in my tulip bed topping soil mix. i really need to study charcoal production methods... perhaps a solar oven could do it... gotta go look now. still gotta do it. *sigh* i'm sensitive to smoke though that it would have to be a pretty well engineered device. *mad scientist chuckle* songbird |

.... Shooting the shit is fine, but without authority, it is just babbling, today's authority is sometimes wrong. i worked for 7 people who were authorities and they were a lost cause. and so i don't trust authorities blindly and find most popular works too light on rigor... because of that i have been trying to get a hold of more studious works lately. i was reading a college level plant physiology textbook a few weeks ago and it ignored so many topics and instead focused on the pet topics of the various contributors. don't get me wrong, it was a good book for me to read but it was very incomplete and i was afraid that many students who had this as their only plant physiology book would be missing so much. now i am looking for other good reads, so recommend away and i will line some of them up and see what they have to offer. and logic is only as good as its premise. if it's valid. You quoted links? only those you included, but many i did not follow because i was offline (as i am now). Citation please. tossing citations back and forth with no personal interpretation on your part isn't a conversation. tell me when you cite a link what it means to you and how it is lived by you. otherwise you are a shadow boxer. do you garden? how do you garden? what do you garden? or i am here to babble then. songbird |
