They planted small olive trees to boost microbial diversity. They split an unirrigated 100-hectare field into three zones, one treated with chemical fertilizer and pesticides; and the other two with different amounts of an organic biofertilizer , consisting of fermented grape leftovers and a variety of bacteria and fungi, along with four types ...
Effective microorganisms enhance the soil's beneficial microbial community, paving the way for sustainable agriculture. These microorganisms consist of naturally occurring microbes, such as photosynthesizing bacteria, lactic acid bacteria, yeasts, and fermenting fungi, which can be applied to increase soil microbial diversity.
Soil microbial communities are characterized in many different ways. The activity of microbes can be measured by their respiration and carbon dioxide release. The cellular components of microbes can be extracted from soil and genetically profiled, or microbial biomass can be calculated by weighing the soil before and after fumigation.
Soil microbial communities experience shifts in the diversity and composition during dehydration and rehydration cycles. [5] Soil moisture affects carbon cycling a phenomenon known as Birch effect. [6] [7] Temperature variations in soil are influenced by factors such as seasonality, environmental conditions, vegetation, and soil composition.
The microbial communities inside the root and in the rhizosphere are distinct from each other, [2] and from the microbial communities of bulk soil, [3] although there is some overlap in species composition. Different microorganisms, both beneficial and harmful, affect the development and physiology of plants.

Soil biology is the study of microbial and faunal activity and ecology in soil. Soil life , soil biota , soil fauna , or edaphon is a collective term that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil- litter interface.
Without soil fauna, microbes that directly prey upon competitors of plants, and plant mutualists, interactions within the rhizosphere would be antagonistic toward the plants. Soil fauna provides the rhizosphere's top-down component while allowing for the bottom-up increase in nutrients from rhizodeposition and inorganic nitrogen.
