Glycan Composites and methods for rendering glycan composites for the treatment of photosynthetic organisms, including the steps of formulating branched glycan deglycosylates into coordination complex compositions resulting in water-borne availability; stability during storage; applying a suitable volume of the resulting mixture to one or more photosynthetic organisms; delivery to photosynthetic organisms; metabolically based growth of crops; enhanced qualities and increased quantities of crops; and systems and compositions for the same.
