Changes in the structure of actinomycete populations in the rhizosphere of vicia sativa species

Abstract

It is a known fact that species of legumes improve the soil they are grown on, but at the same time, they
produce the so-called rhizosphere effect or rhizodeposit that has a selective effect on the microorganisms
which are considered "fertility effectors" for soil. From the three studied area the highest number of
actinomycetes was found in edaphosphere and the lowest number in the area influenced by roots. Among the
few factors under research for the purpose of this paper, humus and potassium were observed to have the
strongest impact on this group. Humidity is a factor that could change the competition between soil
microorganisms and plants in the soil for N and it could affect the stability of aggregates.
