Various embodiments of the present technology provide methods and systems for soil enrichment. The systems may comprise a bioreactor system coupled to an initial treatment system for the cultivation of a live microorganism culture containing organic nutrients on an agriculturally effective scale. The systems may be automated and/or portable for practical applications onto target fields. The live microorganism culture may be delivered onto the soil of the target fields, enriching the soil with the organic nutrients that become bioavailable to crops growing in the soil. The soil enrichment system may provide a sustainable approach to agriculture that may efficiently enhance the natural processes of the native soil of any crop.
