The role of mineral components. The basic mineral components are: The nitrogen is absorbed by plants from soil in the form of ammoniac or nitricacid salts. But in the soil there are many organic compounds of nitrogen in the form of protein substances left from died plants and animals. The majority of plants can't assimilate directly these complex organic nitrogen compounds. But organic nitrogen can be converted into mineral compounds available for plants. The large quantity of bacteria and fungi living in soil nourish by organic nitrogen compounds. They decompose the proteins into wastes of dead plants and animals. With this decomposition in the soil nitrogen is formed; the size of bacteria is very small (not more than 2·10-6m) and in one gram of soil with average fertility there are several hundreds of millions of bacteria and in one gram of black soil there are – up to 3 billions. In spite of small sizes these bacteria and fungi convert in the soil large masses of organic wastes. The most of ammonia formed in the soil in the result of decomposition of organic wastes by bacteria oxidizes by special microbes into nitrous acid after that into nitric acid which part begin to be the feed for plants. The significant part of nitrogen links in the soil by special microorganisms – bacteria that fix nitrogen. The biggest contribution of fixed nitrogen gives the tuber bacteria. But in the best cases we can insert up to 200 kg of nitrogen in 1 ha by biological way. For this necessary conditions for reproduction and development of microorganisms must be created. It is necessary to note that in good soils the quantity of microorganisms can be from 10 up to 50 tons in 1 ha. And like it was shown earlier so large quantity of various microorganisms forms special associations each of them is able to convert insoluble nourishing macro- and microelements into assimilated forms and in addition to fix atmospheric nitrogen and nourish by it plants. Alive organisms fulfill great work without which the soil won't have its main property – fertility. It is necessary to note that there are diverse contacts between soil organisms. All this system is in the state of continuously changing balance. |

In the process of decomposition the fungi also take part. Besides with the help of its ferments they take part in the decomposition of lipids, carbohydrates, proteins and other compounds of soil. The fungi assimilate the nourishing substances directly from the organic substance and in some extent provide by them and water the plants. The algae take active part in the forming of soil and increasing of soil fertility. They develop on the surface in the top layers of soil and with the help of solar energy. The quantity of algae in soil depends on its type, humidity and temperature. With the significant moistening in 1 g of soil there are up to 60 – 100 thousand of algae. Some algae conduce to vital functions of bacteria that fix nitrogen. Their development caused the activity of lichens – special colonies where fungi and algae live (symbiosis). The algae spun by fungus are batter provided by water and mineral substances but the fungus obtain only organic feed – dead and weakened cages of algae. As it was shown earlier the plant rather good develops with the availability of potassium, nitrogen, phosphor, calcium, magnesium, iron and sulphur in soil. After that we made sure that for obtaining qualitative, full-value production, for development of all plants it is necessary to insert into soil microelements manganese, boron, copper, zinc, cobalt, titanium in small quantities. Besides microelements play significant role in the forming of ferments, catalysts, coferments and other substances conducing to forming of more valuable vitamins and physiologically active substances of another 20 microelements: lithium, vanadium, chrome, nickel, germanium, zirconium, tungsten, silver, tin, gallium and others. Some microelements serve as substitute of those microelements that are in small quantities for forming of ferments, coferments and other substances. So the perspective fertilizers must contain all the types of aforesaid mineral and organic substances that are compatible among themselves and are the complement of each other that is to say that the soil must be “alive”. That is the gist of its fertility and result of influence of CHMF. |
