Organic carbon formation in soil is almost impossible without the help of organic matter. Naturally, various bacteria have a great role in the formation of organic carbon and humus in the soil. In the process of decomposing organic matter, not only one specific bacteria, but many types of bacteria perform this task at the same time. It is slightly different, bacteria work in this process too) gases like carbon dioxide, oxygen, hydrogen, nitrogen are used and produced in the process of decomposition, while toxic gases like ammonia, methane, sulfur, ozone are produced in the process of decomposition. Decomposition process is good in open air or airy place but if this process is done in closed condition, instead of decomposition process (fermentation) is going on. Now let's turn to the vineyard, in the vineyard every spring, organic matter is added to the soil, the biggest component is compost, most of the farmers make pits near the trunk of the grape vine or two and a half feet apart and cover it with soil, often this compost is raw, not complete. After being buried in the soil, further decomposition takes place. This process of decomposition generates a lot of heat, (sometimes 50 to 65 degrees Celsius) and this process takes place close to the grape roots. The outer skin of the roots is very delicate, so the roots get a kind of shock, in addition, the energy (heat) produced during the decomposition of manure turns into its own fuel, manure is not a carbon, but works as a medium, and oxygen and nitrogen, which are not in the soil, are consumed as carbon. are falling, (oxygen burns more and nitrogen burns a little less) only in this way, damage is possible due to the lack of many types of nutrients on the grape vine, the lack of nitrogen in the soil means not only the lack of nitrogen, but also many other nutrients are not picked up by the roots without nitrogen. (Only for this reason, when green manures are applied to crops like jute when they are green and still wet, they create a huge nitrogen deficiency in the next crop). Many a times, despite supplying all other secondary and micronutrients to the grape vine, only because of the lack or absence of the nitrogen element that carries those elements, the grape vine shows the deficiency of these elements, besides this, due to the lack of oxygen and nitrogen in the soil, the formation of humus in the soil also slows down. Therefore, while giving manure in the vineyard, it should either be 100 percent decomposed (composted) first, and if that is not available, such manure should be spread or spread uniformly over the entire bed in the upper layer of the soil without burying it in the ground and then cover it a little. If other chemical fertilizers are to be added, other than super phosphate should not be mixed with manure or compost. Put it alone.
Now let's think a little differently, let's see what happens when nitrogen-containing chemical fertilizers like urea, ammonium nitrate are added to the decomposition process along with manure or organic matter. This mixture (manure and urea) accelerates decomposition, and nitrogenous fertilizers are quickly converted into nitrates and ammonium nitrates. Since other nutrients (other than nitrogen) are not broken down as quickly due to less time for decomposition, nitrate alone is more readily absorbed by the roots, (it's kind of like horses next to horseradish, nitrate is horse and horseradish is other nutrients). keeps doing Either shoots the top of the vine or destroys the pregnancy of the bunch. Second, it reduces the resistance and vigor of the vine, so chemical fertilizers should not be given together with organic matter or given very little, (hard pruning will work at the time). Of course, movement does not nitrite, but the load of excess negative charge on the root causes all of this.
