Project summary

In practice of soil ecology and plant cultivation scientific and practical displacement of interests from traditional kinds of mineral and organic fertilizers to bacterial fertilizers is currently observed. Bacterial fertilizers are safe, effective and do not break the ecological balance of the environment.

For several years European network project IMPACT has been in progress. Its objective is to create a biotechnology to control soil fertility through plant nutrition and its protection with use of ecologically safe communities of microorganisms, both natural and modified.

Similar projects are carried out for a long time in Japan, where effective microorganisms stimulate rhizosphere microflora.

The state program of manufacture of biological agricultural products also operates in India. The program implies the improvement of plant cultivation due to biogenic management of soil fertility and plant nutrition.

For several years the laboratory of soil biotechnology in the Kyrgyz-Russian Slavic University has been engaged in studying influence of bacterial fertilizers on biological activity of soil and rhizosphere plants. ISTC Project « Reception of new materials as a result of organic raw material bioconversion was devoted to this problem and has been recently completed. Bacterial fertilizer "Gumovit" has been produced. The biotechnology of its production and use in agriculture has been developed. Field trials of the fertilizer provided interesting data on:

· Increase of productivity of agricultural crops


· Increase of groups of microorganisms valuable from the standpoint of agronomy
· Increase of the content of soil nitrogen
· Elimination of root crop diseases

As a result of the trials, the wave nature of changes of biological activity of soils being affected by bacterial intervention has been established. In this context, a possibility of control of soil fertility by synchronizing microbiological and soil- rhizosphere processes has been placed in focus. .

The process of space-time biogenic excitation in soils is biophysically provoked by bacterial preparation and is determined by the chemotactic wave. This wave, in turn, results from changes population activity of soil microflora.

The zone of the population autowave is a zone where soil activates and contains increased concentrations of agriculturally valuable organisms. Biochemical processes in this zone enhance increasing thereby mobile forms of plant nutrition. Laws of change of rhizosphere properties (zones of plant root terminations) are also of autowave character. Within the framework of the given project it is supposed to study in detail both these processes as well as to try synchronizing them to achieve the best agronomical effect at entering bacterial fertilizers into ground.

Objectives of the project:

· Define dynamic characteristics of soil population auto-wave depending on intensity of soil biogenic perturbation;


· Define dynamic characteristics of a zone of rhizosphere root terminals (with and without stimulation) depending on the intensity of soil biogenic perturbation;
· Develop biochemical and biophysical factors of interaction of bacterial fertilizer with the basic agronomical valuable physiological groups of soil microflora.
· Develop methods of synchronization of soil-rhizosphere auto-wave processes;
· Define influence of auto-wave processes synchronization on productivity of experimental crops;
· Develop analytical and technical means to control soil fertility and plant nutrition;
· Commercialize project outcomes.
