Title : Microorganisms and Agriculture: a successful partnership

Abstract:

The degradation of cultivable soils has intensified over the years and the search for solutions that bring modern agriculture closer to the ideal of sustainability becomes increasingly necessary. Extensive cultivation causes a drastic reduction of soil nutrients.

Replacing these nutrients represents a high financial and environmental cost once chemical fertilizers are the major source of crop nutrients. The development of new strategies to mitigate the effects caused by intensive agriculture have become more relevant.

Various mechanisms are used by microbial strains in order to enhance nutrient uptake, improve soil fertility and increase crop yields such as nitrogen fixation, potassium and phosphorus solubilization, excretion of phytohormones, production of substances suppressing phytopathogens and guarding plants from abiotic and biotic stresses. In the year 2022, the world saw a global fertilizer supply crisis. At times like these, new technologies and strategies using microorganisms as bioinputs come to relevance again.

The environmental benefits and gains in productivity and plant protection, in the use of microorganisms, are already widely known and new molecular biology tools expand the possibilities of applicability and increase the safety of their use. There are still many challenges along the way from the laboratory to the application on farm. Farmers need more information about bio-based products and their differences from chemicals in their application, preparation, and compatibility with other products.

The legislation regarding these products still needs to be adjusted. And in addition to these challenging issues, effective ways to ensure that these organisms are viable for use. The development and improvement of these technologies will certainly contribute more and more to a more
sustainable agricultural production, which also meets the demands of farmers in their reality.
