Carbonic acid (formula H2CO3) - weakdibasic acid. When the solutions are heated, they decompose into carbon dioxide and water. This acid is of great importance not only for animals, but also for plants. In the human body, H2SO3, as well as its salts are part of the buffer systems of the blood. With the help of buffer systems, the acid-base balance in the body is maintained, which is necessary for normal vital activity. Dissociation of acids in an aqueous medium leads to the formation of anions and cations. The concentration of ions is of great importance for the flow of many biochemical processes in the organism of animals and plants. In some diseases, the active blood reaction shifts to acid (with ulcer of the duodenum and stomach) or alkaline (with sepsis, pneumonia) side. With acidosis, the concentration of hydrogen ions increases. Such changes in turn provoke the development of a coma, which in the end results in the death of the animal itself. With alkalosis in the blood, the concentration of cations increases, which leads to tetanus and the death of the animal.
Carbonic acid is formed in the processinteraction of CO2 with H2O. Most researchers believe that the incredible development of vegetation in the primitive world is associated with a significant concentration of carbonic acid in the atmosphere. The most intensive growth was observed in those plants that were grown with an increased (5-10%) concentration of carbonic acid in the atmosphere.
It should be noted that the plants are halfof carbon. Carbonic acid feeds the plant, while promoting the solubility of the mineral components of the soil. Therefore in this case it is a necessary component of the soil. Since carbonic acid inhibits nitrifying microorganisms, the soil must contain a minimum concentration of it.
Therefore, in order to obtain high yields,balance the concentration of said acid. Scientists in their experiments found that with the daily introduction of carbonic acid (400 cm3) and air (1200 cm3) into the soil, it produces twice as many plants as that which did not contain these compounds.
Rural soil is characterized by abundanceair, so in it the processes of nitrification and decay are very intense. It is established that leaves in the forest completely decompose during the year. Such energetic nitrification occurs also in the steppes. During the decomposition of organic substances, a significant amount of carbonic acid is released. The latter is one and a half times heavier than air, so carbonic acid penetrates deeper into the soil than air, and there it has a beneficial effect on mineral components.
With deep plowing, organic residuesfall into deeper layers of soil where there is no O2, but there is an abundance of carbonic acid. In this case, nitrification is extremely slow. Under these conditions, the mineral components are not decomposed and the nitrogenous compounds are not formed. Huge pieces of dung for years lie in the ground, not decaying. Landowners are forced to buy synthetic fertilizers (cainite, superphosphate, Chilean nitrate). Innovative technologies of soil cultivation allow increasing the yield of plants. This is due primarily to the fact that in the process of processing the soil in the upper layers of the soil remain organic residues. Optimal conditions for the development and reproduction of nitrifying microorganisms are created.
Phosphorus, which is in the soil, is not alwaysassimilated by plants. Three-base phosphoric acid is a hardly soluble compound. Therefore, the soil, rich in phosphoric acid compounds, turns into infertile.
