According to the invention, the productivity of cultivated plants is controlled by a microbiological process. At least one telluric microorganism having a favorable rhizospheric effect on a plant is embedded in a polymer gel. Fragments of the gel are then inoculated into the rhizosphere of the plant. The invention also relates to a process for preparing the required fragments of polymer gel. Polymerization of the gel is carried out in the presence of a culture of the desired microorganism, and the polymer block is thereafter broken up prior to use. |

DETAILED DESCRIPTION We claim: 1.
A microbiological process for controlling the productivity of cultivated plants, which comprises inoculating into the rhizosphere of a plant fragments of a polymer gel in which are embedded a least one telluric microorganism having a favourable rhizospheric effect and capable of being embedded in said gel.
2.
A microbiological process according to claim 1, wherein the finely divided polymer gel is diluted with a predetermined quantity of the soil to be inoculated so as to obtain an inoculum, and this inoculum is applied in the vicinity of seeds of said plant by mixing it with the soil.
3.
A microbiological process according to claim 2, wherein the finely divided polymer gel is obtained by cutting into fragments at least one block of polymer gel stored in a medium selected from the group consisting of buffer solutions and salt water.
4.
A process according to claim 1, wherein the embedded microorganism is capable of multiplying from the polymer gel when the polymer gel is placed in a culture medium for said microorganism.
5.
A process according to claim 1, wherein the polymer gel is selected from the group consisting of polyacrylamide gels and silica gels.
6.
A process according to claim 5, wherein the polymer gel is a polyacrylamide gel.
7.
A process according to claim 1, wherein the microorganism having a favourable rhizospheric affect is selected from the group consisting of diazotrophic bacteria, microorganisms solubilising insoluble phosphates, microorganisms solubilising potassium from potassium-containing silicates, microorganisms producing growth-regulating substances and microorganisms providing resistance to phytopathogenic agents.
8.
A process according to claim 7, wherein the diazotrophic bacteria are selected from the Rhizobium species.
9.
A process according to claim 7, wherein the diazotrophic bacteria used are selected from the group consisting of the Spirillum species and the Enterobacter species.
10.
A process according to claim 7, wherein the microorganisms solubilising insoluble phosphates are selected from the group consisting of Bacillus, Pseudomonas, Enterobacter and Micromycete species
