The fertility and productive value of soil are closely related to the physical and chemical properties of the soil as well as its biological activity. This activity is related to the intensity of microbially catalysed processes of transformation of organic and mineral substances contained in the soil. These processes are closely correlated with the abundance and biodiversity of soil microorganisms, especially bacteria, and the activity of enzymes produced by them. In this article we have compared some physicochemical properties of soil derived from conventional and organic farms and microbial communities inhabiting these ecosystems. We aim to investigate whether the soil management regime affects the abundance and diversity of these environments in terms of bacteria. Some differences in microbial communities were observed, but the rhizosphere of plants from organic and conventional soils does not harbour separate microbiomes. Albeit, the method of fertilization influences the diversity of soil microorganisms. A greater diversity of bacteria was observed in soils from farms where organic fertilizers were applied. Soil pH and activity of some soil enzymes were also shown to differ between organic and conventional soil cropping systems.
土壤的肥力和生产力与土壤的物理和化学性质以及其生物活性密切相关。这种活性与微生物催化土壤中所含有机和矿物质转化过程的强度有关。这些过程与土壤微生物（尤其是细菌）的丰度和生物多样性以及它们产生的酶的活性密切相关。在本文中，我们比较了来自传统和有机农场的土壤的一些物理化学性质和栖息在这些生态系统中的微生物群落。我们旨在研究土壤管理方式是否会影响这些环境中细菌的丰度和多样性。虽然观察到微生物群落存在一些差异，但有机和常规土壤的植物根际并不存在单独的微生物组。然而，施肥方式会影响土壤微生物的多样性。在施用有机肥的农场土壤中，观察到细菌的多样性更大。土壤 pH 值和某些土壤酶的活性也显示出有机和常规土壤耕作系统之间的差异。
