Orchard crop species can influence the soil microbial population by releasing root exudates, which are compounds released by plant roots into the soil. Some crop species exude compounds that are more beneficial for certain groups of microbes, while others exude compounds that inhibit the growth of certain groups. Additionally, different crop species have different root systems, which can affect the physical structure of the soil and the availability of water and nutrients, which in turn can influence the soil microbial population. This study aimed to determine the soil microbial diversity of some orchards during different seasons to advance knowledge about the role of microbes in the balance of the orchard ecosystem. The research was carried out in a mixed orchard in Iasi county. Effects of season (i.e. autumn, spring and summer) and land use (apple orchard, plum orchard and cherry orchard) on soil microbial populations and microbial community structures were determined using the Petri dish culture method on different culture media.
