Turtle Posted May 24, 2006 Report Posted May 24, 2006 As far as where I live, I'm in the upper right hand corner of the US, about 75 miles north of Seattle, Washington, in a rural area just below the Canadian border. My wife and I own six acres of land in the hills where we play at organic gardening, amongst other things. "Well, ain't that something!" Long pause. "Say, you got any more of that home-made raspberry wine in the fridge?" "Sure Auggie, help yourself." Around here, everyone's used to my crazy notions. I'm known as the mad scientist/songwriter/farmer/computer geek with the loud electric guitar and the finest raspberry wine ever made. I owe it all to alpaca poop, I tell them. You gotta love the Pacific Northwest for the friendly people. (Even a recluse notices:hihi: ) I used to go up to an annual kite retreat at Fort Warden years ago. I have to ask if you were looking South or standing on your head gost when you said 'upper right hand corner of US"? On the charcoal, are you grinding it up too? How fine & by what means?Gettin' Pestle Elbow,Turtle
gost Posted May 24, 2006 Report Posted May 24, 2006 Oooops! Too much raspberry wine, plus I think I'm geographically dyslexic. Upper LEFT. On the upper LEFT coast of the US. Come to think of it, wouldn't it be on Michael's RIGHT, since he lives south of the equator, and therefore standing on HIS head? As far as grinding the charcoal, I used the rock that you see in the upper part of the pic I posted above. The stuff powderized very easily and you could pretty much do it with your fingers if you didn't mind the mess. The flower pot took a little more work.

Come to think of it, wouldn't it be on Michael's RIGHT, since he lives south of the equator, and therefore standing on HIS head? Far too much raspberry wine:) My wife would kill for Raspberry wine.Many years ago travelling in Italy, with children aged 2 and 7, she saw raspberries everywhere. (We were staying in a little hotel near Venice)She tried to order some. Could not find the word.Her schoolgirl Latin desserted her (pardon the pun):eek: Caesar apparently never crossed swords with a raspberry.The closest we got was "Cassis"She (wife) was not impressed but the kids loved it.It was some time before we worked out why we had such silly,merry, hyperactive kids after dinner every night.:) A friend, a Qantas engineer of long standing, was sent to Seattle, for a year, to watch Boeing build Qantas a plane.His wife and he said that of all the places in the world they had visited, ( a lot working for Qantas), they would happily live in Seattle. Seattle sounds great (They were picked as Aussies immediately as they tried to put their washing out in the sun to dry.):) Now, for an Australian, that is shockingly high praise. Contrary to the belief of US customs, not everyone is trying to sneak over to the States to live. (Which is the way they made us feel when we visited). Apart from minor aberrations like "Crocodile Dundee" we have been trying to keep Australia a secret.Which when I travelled was easy. Americans get very confused by concepts like Geography.( eg your last post-the prosecution rests):) "You speak lovely English for an Austrian" "What do you do in Australia""O, we run a nursery""What made you start a nursery in Australia?"Um . . well . . um. . we were born there!"."O, I didn't know people were actually born there.!!??"ummmmm . . . . . . . . .. . . .":confused: Give me a stack of bibles I swear both encounters were true. The first one several times. The last is etched in memory. I LOL at your encounter with your neighbour.The question is how do you convince him you are not a nut case?Pehaps you need to grow bigger raspberries or whatever.-- Michael :)
Michaelangelica Posted May 24, 2006 Report Posted May 24, 2006 I looked up cation exchange capacity on the web and found all the uni notes incomprehensible. how does anyone pass? I guess they study chemistry at school for a start.I also guess, if I understood this, I might figure out why some of my soil has a Ph of 9 This was one of the better ones from Washington State Unihttp://soils.tfrec.wsu.edu/webnutritiongood/soilprops/04CEC.htm Cation-Exchange Capacity (CEC) Cation-exchange capacity is defined as the degree to which a soil can adsorb and exchange cations. Cation-a positively charged ion (NH4 +, K+, Ca2+, Fe2+, etc...) Anion-a negatively charged ion (NO3 -, PO42-, SO42-, etc...) Soil particles and organic matter have negative charges on their surfaces. Mineral cations can adsorb to the negative surface charges or the inorganic and organic soil particles. Once adsorbed, these minerals are not easily lost when the soil is leached by water and they also provide a nutrient reserve available to plant roots. These minerals can then be replaced or exchanged by other cations (i.e., cation exchange) Top of page CEC is highly dependent upon soil texture and organic matter content. In general, the more clay and organic matter in the soil, the higher the CEC. Clay content is important because these small particles have a high ration of surface area to volume. Different types of clays also vary in CEC. Smectites have the highest CEC (80-100 millequivalents 100 g-1), followed by illites (15-40 meq 100 g-1) and kaolinites (3-15 meq 100 g-1). Examples of CEC values for different soil textures are as follows: Soil texture CEC (meq/100g soi)Sands (light-colored) 3-5Sands (dark-colored) 10-20Loams 10-15Silt loams 15-25Clay and clay loams 20-50Organic soils 50-100 In general, the CEC of most soils increases with an increase in soil pH.????????????? and this academic site http://www.microsoil.com/CEC.htmThe disadvantages of a low CEC obviously include the limited availability of mineral nutrients to the plant and the soil's inefficient ability to hold applied nutrients. Plants can exhaust a fair amount of energy (that might otherwise have been used for growth, flowering, seed production or root development) scrounging the soil for mineral nutrients. Soluble mineral salts (e.g. Potassium sulfate) applied in large doses to soil with a low CEC cannot be held efficiently because the cation warehouse or reservoir is too small.and anotherThe CEC is the abbreviation for the cation exchange capacity of the soil. Any element with a positive charge is called a cation and refers to the the basic cations, calcium (Ca+2), magnesium (Mg+2), potassium (K+1) and s odium (Na+1) and the acidic cations, hydrogen (H+1) and aluminum (Al+3). These are from a huge variety of discussion groups all had a slightly differt take on cation exchange capacity. I found them interestingI hope you do too. In its simplest form, cation exchange capacity relates to that mineral's abilityto retain nutrients to be absorbed by plant roots. I'm sure a chemist couldprovide a much more meaningful definition, but it has to do with positive andnegatively charged ions and their relationship with soil particles.Pam - gardengal Topic in rec.gardens > Cation Exchange Capacity> The ability of a soil or growth medium to retain nutrients against leaching> by irrigation water or rainfall is estimated by measuring the cation exchange> capacity (CEC).

Instead, I would sayroots can excrete acids or bases depending on the environment. Also,roots have a cation exchange capacity. Tree roots should be able to excrete acid (hydrogen ions) or bases(hydroxyl ions or carbonate ions) depending on the ionic compositionof the soil solution. If most or all of the nitrogen is present as nitrate (NO3-), thenroots excrete hydroxyl ions (OH-). With all nitrogen as NO3-, rootsgenerally take up more anions than cations so must excrete some OH- tomaintain cation-anion balance. The hydroxyl ions may cause the soilsolution pH to rise. Roots have to have a net cation uptake aboutequal to the net anion uptake on a charge basis in order to maintainelectroneutrality. If a significant amount of nitrogen is present as ammonium (NH4+),then most roots excrete hydrogen ions (H+) . With a significant amountof NH4+, roots generally take up more cations than anions so mustexcrete some H+ to maintain cation-anion balance. The hydrogen ionscause the soil solution pH to decline. In some species of iron-efficient plants, the roots excrete largequantities of H+ even with all nitrogen as nitrate. This occurs whenthe plants become iron deficient. The decline in rootzone pH greatlyincrease iron availability. The shrub, Euonymus japonica, responds toiron deficiency in this way (Hershey and Paul 1983). In common philodendron (Philodendron scandens ssp. oxycardium), theroots excrete H+ and the soil solution pH declines even when allnitrogen is provided as nitrate. This pH decline occurs even when theplant is not iron deficient (Mattis and Hershey 1992). The above phenomena have not been studied for too many species. Roots have a cation exchange capacity because of negative charges ontheir cellulose surfaces which are satisfied by cations, such ascalcium (Ca++). Roots have an absolute requirement for calcium andboron in the external solution to maintain membrane integrity.from sci bio botanyFrom: Bill Robinson - view profileDate: Fri, Feb 5 1999 12:00 amEmail: "Bill Robinson" <rose [email protected]>Groups: rec.gardens.ecosystems Nicole wrote:>Does any one know what buffer capacity is exactly?

Righteously good questions! This ought to take about 10pages and be its own sub-section in the FAQ. "The Nature and Properties of Soils" by Nyle C. Brady andRay R. Weil is a first rate reference and it has a fair amountof information on soil buffering capacity and the role it playsin the soil environment. They define buffering capacity as,"The ability of a soil to resist changes in pH. Commonlydetermined by presence of clay, humus, and other colloidalmaterials." "Cation Exchange Capacity" is kind of like that but not really.Brady and Weil define " Cation Exchange Capacity" as, "Thesum total of exchangeable cations that a soil can absorb.Sometimes called 'total-exchange capacity', "base exchangecapacity' or 'cation adsorption capacity'. Expressed incentimoles of charge per kilogram of soil." Soils with a high soil buffering capacity will also have a highcation exchange capacity. Soil pH shapes a lot of the chemical and bio-chemical reactionsthat occur in the soil. It all goes back, at bottom line, to the verycomplex, inter-reactions involving the soil environment, the soilorganisms, and the living plant roots. Soils that are low in colloidalmaterial, which on a practical basis means organic, usually don'tperform as well as soils with a high colloidal content but there ismore to it than simple cations. It also involves biology. Rodale's made the statement many years ago that the way to feedthe garden was to feed the soil organisms. He was right. The issueis the best way to feed the soil organisms. A soil rich in organic isgood food for the soil organisms and the organic helps to stabilizethe pH which helps in the nutrition in a whole number of ways.from rec.gardens ecosystems and from Craig BingmanTopic in sci.aquaria Do I understand you correctly in that you claim that GAC has a lowercation exchange capacity than laterite? My interest in using organic matterto bind ions was sparked by reading 'The Soil-Plant System in Relation toInorganic Nutrition' by M. Fried and H. Broeshart from which I quote "theorganic matter also provides a reactive surface which both adsorbs cationsin exchangeable positions formed by COOH and OH groups and also may complex such ions as Fe, Mn, and even Ca and Mg. This adsorbtion and complexing of nutrients can be appreciable -- The cation exchange capacity of humic acid approximates 250 to 400 meq/100g, which is threefold that of the montmorillonite-type clays and 30- to 100-fold that of the kaolinite type." This indicates that organic matter has a large potential to supply rootswith nutrients. My thoughts about filter carbon were with hopes to takeadvantage of the high exchange capacity while eliminating the anaerobic muckand H2S gas and water over-enrichment that usually results from letting organic matter decay in the substrate. Upon rereading it seems that they're really making a point about humic acid more than anything, which is presumably not available in filter carbon and probably only available where there is decay. This agrees with the old advice about adding peat to the substrate. However, the hope might still be that the COOH and OH groups still existin GAC, if it's made from living plants. I have no idea and I hope thatsomeone else knows if filter carbon is the complicated end result ofprocessing plants (e.g. coconut) or if it's nearly purely graphite whichutilizes the "hydrophobic" effect to trap organics. (If this is the case thenwhy do we worry about carbon removing trace elements which exist in ionic formfrom the water?) Here are two possible drawbacks to using carbon. First, it was mentionedon another recent thread about carbon that some companies process it withphosphates: enough said. Second, I ran across an excellent review articlein the Journal of Aquatic Plant Management (vol 24, Jan 1986) which citesresearch concluding that too much organic carbon in the substrate limits thethe growth of submerged aquatics (Aquat. Bot. 12:157-172, J. Ecol. 71:161-175).However this was presumed due to high concentrations of organic acids and itwas also noted that "Low level accumulation of organic matter in such sedimentscan apparently stimulate growth due presumably to improved ionic exchangeproperties and increased sediment nutrient content." So it seems like onewants to either avoid or use sparsely any organic matter which might decay.Water movement through the substrate and water changes might circumvent this,but this danger was the idea behind the filter carbon. 2) So clays may be the way to go. I do have a slight aversion to laterite'shigh price in aquarium circles, but what I really dislike about it is thatwe (most aquarists, myself included) know little about why it is so muchbetter at ion exchange than other clay minerals. Yes, I read the thread fromlong ago between Jeff Frank, Oleg, George and others on how laterite is atropical clay which undergoes weathering over a geologic time scale and hasmost Ca and Mg removed and has charged sites which attract nutrient ions, etc.,etc.. But these are still vague descriptions which fail to tell us why isis different from other minerals or some stuff I might dig up in my backyard.Once I know how it works and why it's unique I'll shut up and buy it :). Here are some more interesting quotes from Fried and Broeshart's book onthe subject of clays: "The secondary minerals [those not present in themagma] are primarily responsible for many of the phisicochemical propertiesof soils that affect plant nutrition. The dominant reactive clay minerals,including the kaolinites, montmorillonites, and illites, derive theirreactivity not only from their fineness of subdivision and broken exposedcrystal edges but also from isomorphous substitution in the lattice, resultingin a net negative charge of the clay particle. It is this net negative chargeand the exposed crystal surface that result in the ionic adsorption ofcation, including nutrient cations. -- The dominant reactive clay mineralsfound in soils are two-layer non-expanding types and three-layer expanding-and nonexpanding-types. -- Within the lattice there are always substitutionsin the three layer minerals. -- These substitutions give rise to exchangeproperties i.e., a net charge on the lattice resulting in the ability toadsorb ions. Lattice substitutions are presumably not common in the two layertype minerals, such as kaolinite, and most of the exchange properties of theseminerals are supposedly the result of the unbalanced structure at brokenedges. -- In many of the 3 layer minerals water can enter between the unitlayers, giving these minerals an expanded structure. -- The concentration ofM(solid) [a nutrient ion in the solid phase] reflects this difference incapacity to adsorb exchangeable cations. Those soils in which the two layerclay minerals dominate (e.g. lateritic type soils) typically contain relativelysmall amounts of exchangeable cations and have a relatively small capacity tohold them. Those in which the three layer clay minerals predominate(e.g. chernozem soils) usually contain large amounts of exchangeable cations and have a relatively large capacity to hold them." The double dashes abovemean that I left stuff out. There is a able in the same section labelled "Cation Exchange Capacityof Clay Minerals." The lowest listed exchange capacity listed is kaolinite(3-15 meq/100g) which is a two-layer type which they seem to be indicatingis present in the lateritic type soils. The highest on the list is (drumroll please...) vermiculite (100-150 meq/100g). You can buy vermiculite atany nursury! This is just an idea but if it is as good as they make it soundthen I'd be willing to dry it out, pulverize it (for maximum surface area) andsee if it can't be made to sink so we can at least use it in the bottomportion of the substrate. Comments? 3) Fried and Broeshart also talk about uncombined oxides: Oxides of Fe andpresumably Al exist as coatings on the clay particles. Much more is known ofthe He oxides owing to the interest of the soil scientist in the nature ofthe laterites." Then later "Al and Fe oxides and hydroxides will, dependingon external pH and salt concentration of the ambient soil solution,disassociate H+ and OH- ions and can therefore adsorb cations and anionsat negative and positive charged spots. The oxide coatings -- provide areactive surface capable of retaining certain anions, chief among whichis Phosphate. It is also becoming apparent that the exchange properties ofsoil are due to contibutions from oxide coatings." This seems to indicatethat the exchange properties of laterite are not due primarily to the crystalstructure but to a coating of Fe2O3 on it, which would account for itssupposed orange/brown color. This might be easily duplicated by adding aniron enriching additive with little or no chelating agent to some of thefiner substrate particles, mixing with water, and allowing to dry in thesun to make a good coating on the particles. I'm sure any soil scientist could tell us if this is the key propertyod laterite, so if you're out ther please post. I haven't seen this stuffdiscussed in previous laterite threads. Also, it is frequently mentionedthat laterite adds a good dose of iron for the plants. If the above is truethen this notion is false since the oxide would be unavailable for uptake andwould function instead as a binding site. There is more interesting stuff in this great book but you can look it upyourself. I'm not a soil scientist and I found this and other good referenceswhile doing a superficial search on trace element nutrition, so I imaginethere's a wealth of knowledge out there on clay composition and what mineralswork best for nutrition. I think these issues ought to be addressed beforeI spend big bucks (on a student budget, not George's) for laterite additives.Thanks for listening if you're still ther and keep the comments comingbecause this subject needs more discussion than lighting or CO2, both ofwhich are well understood.Jim Kellyemail jke [email protected] Well I finally managed to covince my wife I needed some chook poo and horse poo from the local (300m away) farm.

Michaelangelica Posted May 26, 2006 Report Posted May 26, 2006 Another very good introductory article on Terra preta:- http://www.philipcoppens.com/terrapreta.html What we know + a slighly different perspective e.g., Philip Coppens Since the latter half of the 20th century, two leading thoughts have come to the forefront of humanity: one is the possibility that we can destroy our planet – and whether our industrialised economy is killing the planet, the second is so-called “terraforming” other planets – making them inhabitable and suitable for human habitation. Both “techniques” transform an existing ecosystem and reside in opposite camps – destruction and creation.Though topical, and for many perhaps theoretical, it is not a purely modern issue, an outcome of Man’s conquest of space, or the science fiction generations that have grown up in the 20th century. During that same century, it has become clear to science that people in the Amazon have created and used similar techniques – two millennia earlier. and Though some of the secrets of this soil have been discovered and will help in provide great help to many impoverished regions, some ingredients of Terra Preta remain unidentified – or at least difficult to reproduce. In fact, one missing ingredient is how the soil appears to reproduce. Science may not know the answer, but the Amazonian people themselves argue that as long as 20cm of the soil is left undisturbed, the bed will regenerate over a period of about twenty years. A combination of bacteria and fungi are believed to be the transformative agents, but the agents themselves remain elusive from the scientific microscopes.

This is from an abstract of a paper presented at the World Congress of Soil Science onThursday, 13 July 2006. The full paper does not seem to be available http://crops.confex.com/crops/wc2006/techprogram/P16274.HTM Terra Preta de Índio (TPI) The high levels of soil organic matter and black carbon strongly darken the color, change the structure, and the hydraulic properties of the soils. The texture is lighter and the workability of TPI is easier, especially when TPI is wet. Because of their easy workability and longer lasting fertility in relation to surrounding soils, local populations intensively cultivate these sites. TPI seem to be a very resilient soil type that keeps their good soil physical qualities even when submitted to intensive soil management. Frequent findings of charcoal and highly aromatic humic substances suggest that residues of incomplete combustion of organic material are important. In Manaus, Brazil we are studying the effect of charcoal amendments to the dystrofic and acric soils in an attempt to recreate some soil qualities showed by the TPI.
Michaelangelica Posted June 21, 2006 Report Posted June 21, 2006 A research article on the clays added to terra pretaVery detailedYou need to be a geologist and chemist to read it but very good. It seems other rocks apart from pottery may have been added to the soil as well? (I am having trouble getting my head arround article-translated form Portugese!) What is cauixi and cariapé?http://www.scielo.br/scielo.php?pid=S0044-59672004000200004&script=sci_arttext most of mineral grains were taken from fresh crystalline rocks and intentionally crushed and introduced into clay material as well as cauixi and cariapé. The above described minerals and organic substances led to identify the following materials as raw materials for the ceramics: 1) clay material derived from weathering (saprolite/mottling zone) of fine crystalline and less frequent sedimentary rocks (indicated by clay-derived minerals and iron oxy-hydroxides, anatase and quartz ); 2) fresh crystalline rocks crushed (feldspars, quartz and rock fragments); 3) organic materials (cauixi and burned cariapé). The abundance of fresh feldspars, rocks fragments and roundless quartz indicate that coarse igneous rocks, e.g. granites, granodiorites, and even rhyolites and quartz of veins were used as temper, after crushing. It's possible that pre-historic Indians extracted the fresh rocks from the same place where they took the clayey saprolite. To improve the plasticity of the raw material they introduce organic material like cauixi and cariapé, crushed quartz, or even old ceramic (waste) crushed, in an old process of recycling. .

CSIRO MEDIA RELEASE 97/583 April 1997 LEGACY OF A THOUSAND BUSHFIRES Australia's soil is even poorer than was thought, says CSIRO Land and Water researcher Jan Skjemstad. Much of our small supply of carbon - an essential element in fertile soil - is in the form of useless charcoal, resulting from tens of thousands of years of bushfires. "The charcoal is mostly carbon, but it is in a form which can't be used by plants or soil organisms," said Mr Skjemstad.

Especially in light of the global warming debate http://www.sdearthtimes.com/et0998/et0998s8.html Another important part of the study was an estimate of carbon content in bacteria. Carbon, of course, is a crucial element in numerous natural processes, so knowing the amount of it could contribute substantially to knowledge of carbon cycles. Scientists assume that carbon in the bacteria that live in soil and subsurface takes up about one-half of their dry weight. The team thus found that the total amount of bacterial carbon in the soil and subsurface to be yet another staggering number, 5 X 10**17 g or the weight of the United Kingdom. Rather surprisingly, the group at Georgia found that the total carbon of bacteria is nearly equal to the total carbon found in plants. Chacmool 1

MAS could be the key to the large scale development of Terra Preta agriculture. I thought, I first read about these soils in " Botany of Desire " by Michael Pollen, or Dr. Jared Diamond's "Guns Germs &Steel" but I could not find reference to them. Wherever, I did not realize their potential. 'Terra Preta' soils I feel has great possibilities to revolutionize sustainable agriculture into a major CO2 sequestration strategy. There is an ecology going on in these soils that is not completely understood, and if replicated and applied at scale would have multiple benefits for farmers and environmentalist. Basically we could have Bio-fuels and non oil dependent soil fertility too.

If pre Columbian Indians could produce these soils up to 6 feet deep over 20% of the Amazon basin it seems that our energy and agricultural industries could also product them at scale. Harnessing the work of this vast number of microbes and fungi changes the whole equation of EROEI for food and Bio fuels. I see this as the only sustainable agricultural strategy if we no longer have cheap oil for fertilizer. I believe, to have fast results, an M-Roots type fungus inoculent and local compost would get this super community of wee beasties populated into their proper Soil horizon Carbon Condos.

I will post some pics of experiments and progress in spring We are stardust, we are golden, we are billion year old carbon, and we've got to get ourselves back to the garden. - Joni Mitchell
