The article presents the results of a study of the number of pathogens in the soil and their transformation into the plant Oriental Goat’s Rue (Galéga orientalis Lam). It is shown that in the period from 2016 - 2017, the highest contamination of the studied soil samples and oriental goat with pathogenic micromycetes of the genera Aspergillus, Fusarium, Chaetomium was observed and reached from 108 to 1010 CFU/g. The results obtained allowed us to conclude that the suppressiveness and fertility of the studied soil samples decreased. In 2018-2020, the pathogen load on the soil decreased as a result of the use of biological plant protection products for the treatment of crops, as well as the implementation of agrotechnical measures and work to destroy weeds. It has been established that the measures taken against micromycetes of the genus Fusarium turned out to be the most effective. The number of fungi of this genus in the oriental goat decreased from 108 to 104 CFU/g. At the same time, the number of micromycetes of the genus Chaetomium both in the soil and in the oriental goat remained rather high, from 1010 to 108 CFU/g. The company is recommended to continue carrying out activities aimed at improving the soil.
