Comparative analysis of factors limiting the functioning of soil microbiome in grape cultivation in the conditions of the South Coast of Crimea and the Autonomous Province of Vojvodina of the Republic of Serbia |

Research interest in the use of soil biological activity indicator for predicting the state and sustainability of natural and agroecosystems has increased significantly in recent years due to climatic changes changing the location and boundaries of established agroclimatic belts. Distinctive features of these changes are unprecedented speed, as well as spatial and temporal heterogeneity. In this regard, the identification of regularities of influence of regional agroclimatic factors on soil microbiota as an indicator of soil health under different types of land use is of great relevance. In this work, an attempt was made to determine the climatic factors limiting the activity of soil microbiome functioning on the basis of calculation of climatic indices in two regions of grape cultivation close in temperature regime but contrasting in humidity. The results of the research showed that the value of basal respiration in the soils of ampelocenoses of the Autonomous Province of Vojvodina of the Republic of Serbia was 6-11 times higher than in the soils of ampelocenoses of the South Coast of Crimea, which is probably due to a sharp deficit of moisture in the latter (moisture coefficient 0.39 vs. 1.13 in Vojvodina). Regardless of the geographical location of wineries, basal respiration of soils in organic vineyards was twice as high as in soils of farms practicing the traditional system of grape cultivation, indicating more favorable conditions for the functioning of the soil microbial community.
