Rizol za soju

Rizol for soybeans is microbiological fertilizer used for the inoculation of soybean seeds with bacteria that fix nitrogen and form nodules in the roots. Rizol for soybeans contains effective strains of symbiotic nitrogen fixers that have high nitrogenase activity.

By applying these bacteria to the seeds, the formation of nodules in the root is accelerated. Bacteria (symbiotic nitrogen fixers) reach the inside of the roots (parenchyma) through the root hairs, where they begin to divide rapidly, as a result of which the nodule is formed in which these bacteria fix nitrogen and transfer it directly to the plant.

What are symbiotic nitrogen fixers and how do they work?

Symbiotic nitrogen fixers are bacteria that form nodules in the roots of leguminous plants (soybean, alfalfa, peas, beans, clover) where they perform nitrogen fixation.

One type of bacterium forms nodules only on (one) appropriate plant species with which it establishes symbiosis- a form of community in which bacteria directly deliver accessible nitrogen to plants, while plants supply bacteria with assimilators (nutrients created in the process of photosynthesis).

The formation of nodules is also influenced by the pH of the soil, the humus content, the mechanical components of the soil, the application of pesticides and mineral fertilizers.

Agrounik has developed a new generation of preparations (Risol for soybeans, Risol for peas, and Risol for alfalfa) where symbiotic nitrogen fixers are applied to a liquid carrier that ensures longer survival of these bacteria on the seed after treatment. Also, these preparations contain indole-30acetic acid, which increases the germination of seeds, the length of the roots, as well as the above-ground part of the plant, and provides a more successful establishment of symbiosis and formation of nodules.

Rizol for soybeans is used to inoculate soybean seeds with bacteria that fix nitrogen and form nodules in the root. The advantage of using a liquid carrier is that the bacteria applied to the seeds survive longer. Inoculation of seeds with Rizol for soybeans can be performed 30 days before sowing. The dried and treated seeds are stored until sowing.

What bacteria Rizol for soybeans contain?

Nitrogen fixatives – bacteria that perform nitrogen fixation in two types:

  • Symbiotic: Bradyrhizobium japonicum – form nodules in soybean root.
  • Associative: Azotobacter sp. – colonize (inhabit) the surface of soybean roots.

Phosphomineralizers – bacteria that convert organic compounds of phosphorus into mineral forms, settle in roots and supply plants with phosphorus in the initial stages of development

First of all, it should be noted that a bottle of 200 ml of Agrounik Rizol for soybeans is enough for bio fertilization of 100 kg of soy and that only the treatment of seeds can be carried out 30 days before sowing.

How to use Agrounik Rizol for alfalfa: Risol for soybeans (200ml) pour in 250 ml of water, or Slavola S. Then the seeds can be further distributed.

The effects of using biofertilizers such as Agrounik’s Rizol for soybeans are numerous and among the most important are:

  • Accelerated nodule formation at the root;
  • Higher seed germination and germination energy;
  • Better growth and development of the root system and aboveground part of the plant;
  • Improved plant nutrition with elements such as N, P, and K;
  • Higher yield:
  • Colored inoculated seeds.
