SĂNĂTATEA SOLULUI – CONDIȚIE IMPORTANTĂ PENTRU DĂINUIREA SĂNĂTĂȚII OMULUI
(CEP USM, 2024) Frunze, Nina
In this work, soil health was assessed, using the relationship between phytopathogenic and suppressive micromycete species as integral indicators of the microbial response to long-term anthropogenic impact. The micromycete communities of the typical chernozem with different humus content of two pedoclimatic zones of the Republic of Moldova served as the object of study. The investigations were carried out by traditional microbiological methods of study. It has been established that in the soil of both ecological zones there is a large number of microscopic fungi, including phytopathogens and toxin formers in the structure of microbial communities. The comparative study of the share of suppressive and phytopathogenic micromycetes showed that their parallel coexistence is presented in different proportions with the obvious dominance of representatives of the genus Fusarium. The predominance of phytopathogenic and toxin-forming species in the structure of the microbial community indicates a state of deep stress in the soil microbiocenosis, an unhealthy development of the soil microflora during its long processing and a poor state of soil health as a whole.
