In this master work was researched macrofloras dynamics variation during the period of vegetation in phyto association and in the soil. Research object: the part of research was accomplished in 2003 autumn by prof. hab. dr. V. Žekonienė in her executive stationary tests in Trakų Vokė. Another part was accomplished at the stationary ground in Modžiūnai fields also not far from the Merkis near Čižiūnai, and Lazdijai and Varėna regions in the light granulemetre composition of soil. Research objective: to value by the field researches the pervasion in the agrofitocenoze in the southeast part of Lithuania in the light composition of soil macrofauna, subject to cultured species of plants and hidrotermic mode in the soil fields. Research methods: the number of earthworms was counted by dig 0,5*0,5m2 and 0,3 m deep the monoliths of soil and by counting the earthworms. According to researches the number of worms depended on species of cultured plants, influence of forecrops and hidrotermic coefficient. The best preplants were perennial grass and winter rye. At the time of researches were found strong correlation links between hydrotermic modes and the number of earthworms. Keywords: earthworms, agrofitocenose, the soil fauna.
