CHANGES IN THE NUMBER OF MICROMYCETES IN THE SOYBEAN RHIZOSPHERE UPON THE APPLICATION OF FERTILIZERS

When cultivating soybeans of the Sibiriada variety in the forest-steppe agricultural landscapes of Western Siberia, it was found that the use of fertilizers (mineral, bacterial, trace elements) does not lead to the accumulation of micromycetes in the soil. During the years of the research, the number of micromycetes varied from 18,7 thousand CFU/g up to 42,3 thousand in the phase of formation of the third triple leaf, in the flowering phase from 14,9 to 36,5 and from 26,7 to 69,6 thousand CFU/g in the maturation phase. The conditions of the year had a significant impact on the change in the number of micromycetes - 57,4%.
