| Just to heat up the topic.. (Are everybody healthy? Catch a cold? Kha-kha-khhh...? Don’t be ill!!!:) What I aways was surprising is that plants didn’t learn how to catch a nitrogen from the air. From the evolution point of view it is a paradox. Listen, plants learned how to catch a quantum of light (very complex phisical task, it was given Nobel prize for that to a man after millions years the plants discovered it, electricity, chemistry and almost nuclear phisics) but didn’t learned how to perform a much easier task – to capture an atom of N). And I was thinking – why? (And I think I am thinking:) And I came to a conclusion that plants didn’t learn how to catch N from atmosphere (like they capture CO2) just because there always were a plenty of nitrogen (N) under their foot. The drilling man’s mind that drilling and drilling and drilling again (and drilling again!) came to a conclusion that it is because there are plenty of nitrogen fixixng bacterias in the soil, so plants rely on them. Is it an answer to the evolution idea? I think – yes! What Ovsinsky found, is that nitrogen fixing bacterias live only in upper layer of the soil. They love oxigen (O2), and don’t love CO2 which inhibit their growth. When organic matter of the soil is decomposing, it produce CO2 (which inhibit nitrogen-fixing bacteria and they don’t produce nitrogen for the plants). What to do in this situation??? (It is the question of the plants, because they need N). They ( plants) found an excellent idea: we (they were thinking as individuals) will remove CO2 by making deep holes in the soil, where CO2 will go down beeing heavier than air. And they done it! Now CO2 beeing heavier then air go down to the soil, connect itself with the water producing carbon acid (CO2+H2O=CH2O3) which increase the solubility of minerals 30 times! Minerals after dissolution in water (with the help of carbon acid) go up in soil by capillarity force and the plants "eat" them. And again and again the process continues millions of years. And now think, why plants have such a long deep roots? They are seeking water?Nnno-o! They are making holes for next generations of them (plants) to withdrow CO2 from upper layers of the soil deeper in the soil to have minerals and nitrogen both. This is the individullity of the plants! (The End of the symphony) Advertisement: The next symphony will be about water (H2O). Prelude: Water is where the plants, not plants where the water.
