Here we report on a range of studies designed to understand the link between heterotrophic bacteria and soil organic matter decomposition as assured by its autochthonous microflora, mainly heterotrophic bacteria. A contaminated soil with olive waste product (OWP) constitutes an environment limiting for the normal microbial population and activities, and, therefore, an unbalance of the soil organic matter cycles is formed. The application of OWP to the soil is recorded to increase polyphenols, organic content and might leaching of nutrients, and limit negative impact on the soil biological activities. This review assesses the impact of OWP application on soil microbial activity as well as explores its relation to soil chemical properties and organic matter turnover.
