Abstract: Biostimulant compositions and methods for enhancing soil organic carbon are provided. A mixture of bioavailable B12 and amino acids phenylalanine (Phe) and lysine (Lys)—was found to enhance soil organic carbon and crop growth due to synergistic effects between the bioavailable B12 and the PheLys. The bioavailable B12 and the PheLys may be derived from various sources, including, e.g., cyanobacteria (e.g., Spirulina—Arthrospira platensis) or green algae (e.g., Nannochloropsis spp.) cultivated under photosynthetically controlled conditions to yield upregulated bio-active compounds such as bioavailable B12 and amino acids. One or more sources may be used to provide the bioavailable B12, Phe and Lys, and algal cultivation may be integrated with additional industries to yield synergistic biostimulation effects.
