The soils, which are poor in organic matter (humus), are less resistant to the constant influence of actively used tillers, so the soils lose such valuable agronomic characteristics as structure, density, porosity, capillarity, water permeability and moisture content, which are indicators of the soil fertility.

It is important that exactly the humus is the primary source of nutrients, since it contains nearly all of the nitrogen containing in soil (98-99%), about 60% of phosphorus and sulfur, as well as a substantial part of the other nutrients. Therefore, the quality of humus layer decisively determines the yield.

Mineral fertilizers, replenishing stocks of nutrients in soil and improving the circulation of nutrients, do not affect the dynamics of the total humus content.

A year application of Vigus causes not only quantitative but also qualitative changes in humus.

The newly formed humus has a high biological activity, and physical and chemical properties of the soil improve.

  • stimulation of all types of microorganisms, which fix nitrogen taken from the atmosphere and make it digestible for cultivated plants;
  • activation of various groups of microorganisms, which are closely related to the mobilization of soil nutrients and the transformation of potential fertility in effective fertility;
  • increase in the number of soil-forming bacteria, microscopic fungi, actinomycetes and cellulose bacteria by 2-5 times!
  • significant activation of those groups of micro-organisms, which participate in the mineralization of organic substances;
  • soil enrichment with available nutrients. The decomposition of organic matter produces a lot of organic acids and carbon dioxide. They influence hard mineral compounds, such as phosphorus, calcium, potassium and magnesium, change their form and make them available for nutrition of plants.

Due to the quantitative growth of silicate bacteria, there is a constant replenishment of exchangeable potassium assimilated by plants. The peloid increases the number of soil microorganisms decomposing sparingly soluble mineral and organic phosphorus compounds. Vigus application improves replenishment of the digestible stocks of nitrogen in soil: the number of ammonifiers increases by 3-5 times, in some cases, a tenfold increase of ammonifiers is recorded; the number of nitrifying bacteria increases by 3-7 times. Vigus application improves living conditions of free-living bacteria, so their ability to fix molecular nitrogen from the atmosphere increases almost by 10 times. Vigus stimulates activity of nodule bacteria Rhizobium trifoli, living in symbiosis with legumes (lucerne, lupine, clover, pea, vetch, beans), as well as rhizospheric microorganisms, living in the zone of root exudates of plants.

The use of the concentrate in small allotments causes changes in humus content not only in the arable layer, but also in the deep soil layers. By activating the microbiological processes in soil, we improve its structure, and it has a positive effect on the water and air balance of soil.


The structure of a simple microbial cenosis:

I – the simplest microcolony (microaggregate: 5-10 microns)
II – a population microcolony of bacteria (30-50 microns);
III – a soil granule, settled by population colonies (300-500 microns);
IV – a microcenters (overall diameter of 0.5-5 mm)
1 – a capillary filled with soil solution;
2 – a membrane of a humic substance;
3 – plant material;
4 – population colonies of microbes;
5 – a soil mineral granule;
6 – a pore.
