Rizol as a seed biofertilizer with symbiotic nitrogen fixers

Before we move on to describe the effects and uses of Rizol for peas, we need to understand what terms such as nitrogen fixation mean, as well as learn what symbiotic nitrogen fixers that are part of our microbiological fertilizer are and how they behave.

What is nitrogen fixation and what is it for?

Nitrogen fixation is the process of converting inaccessible, atmospheric nitrogen into accessible compounds (NH4) that we can further use like everything else on earth.

Nitrogen, which is about 78% in the atmosphere, becomes available to the rest of the living world thanks to nitrogen fixers – microorganisms that can only use gaseous nitrogen from the atmosphere and convert it into ammonia.

How do symbiotic nitrogen fixers work?

Symbiotic nitrogen fixers are bacteria that form nodules in the roots of leguminous plants (soybean, alfalfa, peas, beans, clover, etc.) and perform nitrogen fixation there. These bacteria are strictly specific to a particular plant species so that one species of bacteria forms nodules only on (one) corresponding plant species.

A symbiosis is established between the bacterium and the plant – a form of community in which the bacteria directly deliver accessible nitrogen to the plants, while the plants supply the bacteria with assimilators (nutrients they have created in the process of photosynthesis).

The biofertilizer from the Agrounik assortment contains appropriate symbiotic nitrogen fixers for a specific crop such as peas (Risol for pea) and by applying these bacteria to its seeds, the formation of nodules in the root is accelerated.

Symbiotic nitrogen-fixing bacteria, which contain Rizol, reach the inside of the root (parenchyma) through the root hairs, where they begin to divide rapidly, as a result of which a nodule is formed in which these bacteria fix nitrogen.

In addition to symbiotic nitrogen fixers, Rizol for pea  also contains associative nitrogen fixers and phosphor-mineralizers that inhabit the root surface after the application of biofertilizers.

Rizol for peas contains effective strains of rhizobia Rhizobium legominosarum bv. viciae, associative nitrogen fixers and growth stimulators that form nodules in the roots of peas inflicted on specific carriers in the liquid state. Symbiotic fixing bacteria through root hairs get into the inside of the root, which is rapidly divide, resulting in forming nodules in which the bacteria fix nitrogen.

Product contains soil bacteria:

  • fixing bacteria (symbiotic and associative) – min 109cfu/cm 3
  • growth stimulators – min 107cfu/cm 3

The seeds of peas mixed with the contents of the bottle, leave it to dry in air and sow. The content of the bottle of 200 ml is sufficient for a seed standard hectare. If necessary, can be added to 100 ml of water or SLAVOL S.

Treatment of seeds may be carried out for several days prior to seeding. Rizol for peas can be mixed with pesticides for seed.

It is recommended to spray Slavol at the stage when the plant is first formed two pairs of trefoil until follicle stages of education.
