Abstract: An objective of the present invention is to provide a method of producing artificial bio-soil aggregates based on foamed concrete for plant growth that can ensure sufficient moisture and plant nutrients for the habitat of plants in non-soil conditions; obtain a lightweight, durable, and deep soil layer, and continuously provide a favorable environment for plant growth. To achieve the above objective, according to the present invention a paste is prepared by mixing cement with an admixture, such as ochre and burnt-furnace slag; foamed concrete is formed by adding foam bubbles with an appropriate foaming rate to said paste, thereby producing soil concrete. When the foamed concrete is used, a designated compressive strength can be ensured and a number of pore spaces are formed, which allow the air to be sucked and expelled therethrough and store moisture therein.
