Irish Girls Win Google Science Fair With Astonishing Crop Yield Breakthrough

An anonymous reader writes Irish teenagers Ciara Judge, Émer Hickey and Sophie Healy-Thow, all 16, have won the Google Science Fair 2014. Their project, Combating the Global Food Crisis, aims to provide a solution to low crop yields by pairing a nitrogen-fixing bacteria that naturally occurs in the soil with cereal crops it does not normally associate with, such as barley and oats. The results were incredible: the girls found their test crops germinated in half the time and had a drymass yield up to 74 percent greater than usual.

      This is normal behavior for a plant inoculated with mycorrhizae; you inoculate the soil with mycorrhizae bacteria and the results are more hardy plants, better nutrient delivery and better handling of dry spells. The webbing produced by the mycorrhizae helps keep soil clumped together better and produces a sponge like mass that holds water better. They also transport nutrients from elsewhere in the soil whereas they would normally flush down with rainwater in exchange for some carbohydrates from the plants roots; plant roots can only really get nutrients dissolved in the water or from soil immediately (within a quarter inch or less). The problem is that anytime the soil is turned you annihilate the local population so you need to inoculate every year with direct contact between the spores and the root mass.

      I wonder how much hunger in the world is caused by crop yeild vs other factors (war, political instability, etc).

      A major factor is land ownership. It is extremely rare to see a peacetime famine where farmers own the land they are tilling. Nearly all peacetime famines result from some sort of collective ownership: communism, feudalism, nomadic grazing of common land, etc. But this research could have a big impact. Most food shortages are in poor tropical countries, and most tropical soils contain very little nitrogen. The girls produced their results on barley, which grows well in Ireland, but not in Africa. Lets see if we can get the same result with rice, maize, or wheat.

      I don't know how they can make the plants not normally associated with those bacteria interact with those bacteria. The truth is that nitrogen fixating bacteria do so at a tremendous expense of energy, usually supplied by root nodules of a plant. If there were such associations with barley and these bacteria, in the past, you can bet your pants on it that it would be already standard practice, and also a sort of darwinist survival of the fittest natural existence. The fact is, unless genetically engineered, barley must not provide these root nodules, unlike alfalfa or beans. However, rice is grown in puddles that have cyanobacteria or similar critters that do fix nitrogen, which, ultimately, end up in the local nitrogen cycle on cycle on critter death. So with rice, with two independent organisms, one living on its own and doing nitrogen fixation, side by side with rice, the situation is similar to growing alfalfa and barley, on the same plot of land, at the same time, independently of each other, side by side, and then somehow picking only the barley, and leaving the alfalfa to rot. Unlike with rice where the picking the rice only and leaving the cyanobacteria in the puddle is easy, with barley and alfalfa (or beans or peas) independent harvesting is so costly, that instead a monoculture of each is grown, in a yearly crop rotation way.

      Another way to put nitrogen into the soil locally, is to run a windmill, into an indestructible nickel-iron tote battery temporarily, from which doing lithium hydroxide electrolysis, then extruding lithium wires to age in the atmosphere, them getting coated with an oxide layer first, then under that Li3N, lithium nitride, which when contacted with water gives back the lithium hydroxide and ammonia, your nitrogen source. With carbon dioxide from a cylinder or even from carefully regulated and cooled (such as using a suction pump from the stack and a bubbler through an aqueous ammonia solution) chimney exhaust gas from natural gas or propane (which are soot free), ammonia can be turned into ammonium carbonate and bicarbonate, baking powder, which is a great fertilizer salt, volatile, but not as volatile as liquid ammonia itself.
      By the way there is a patent on corroding metallic lithium pieces in air, whereby a thin surface oxide coating forms at first, and then the corrosion under that continues as the pure nitride, at room temperature, from around 1970, give or take. Google and the USPTO are so great at hiding it right now, which is why I assume this post was made, because that's such an important patent to hillbilly farmers, that expired, and the powers that be, such as those present at Google or the USPTO, would love to repatent the whole thing and sue the shit out of every poor "kulak" over it. Oh well. So anyway, true it's a slow process and wastes some of the lithium as oxide, but it does not require pure oxygen free nitrogen, expensive reaction vessels to heat lithium metal in, or even high temperatures, unlike the other processes that rely on heating lithium with pure nitrogen. All you really need to invest in is the lithium hydroxide to lithium metal electrolysis, the lithium recycled, and the process using excess electric power coming from a windmill or a solar panel array. The Edison nickel iron battery is indestructible, it can be drained to zero and kept there forever, has no memory, unlike nicad with memory or lead acid that self drains and self destructs if allowed to stay at 0 charge for a long time, and other type batteries with their issues, however, while it is hillbilly friendly, it too has issues, it is not very efficient at energy storage because of hydrogen gassing, and also it quickly self depletes on charge completely within about a month, so it won't hold charge for a long time, and you gotta convert the energy in it into some other, more permanent storage, either as fuel or fixed nitrogen fertilizer.

    It was observed that Oats treated with a higher concentration of r.japonicum (4x106 CFU/ml) produced a greater dry mass (p=0.0248) and longer length (p=0.0043) than water treated seeds.
