Re: sunflower seeds
There's actually quite a bit of nutrients in Blackstrap Molasses besides Iron. Though the thought of it not being broken down enough for use as is as merit.
There has been a definite improvement in fruiting plants noted. Let me see if I can find some sources.

[Description/Abstract Auxein Corporation is demonstrating for commercial use an organic acid phytochelate, derived from what would otherwise be a discarded portion of
Sugar cane, that could increase the domestic
Sugar industry's profit margin from near zero to 7%. Along with helping a struggling industry, the phytochelate will bring substantial improvements to crop and tree production and greatly reduce the environmental threat posed by nitrogen-based fertilizers. Currently, the amount of fertilizer used produces harmful levels of run-off that contaminates ground water with unwanted nitrogen. By utilizing organic acid phytochelates, which assist plant growth by unlocking minerals stored in soil, fertilizer use can be dramatically reduced. This would improve crop yields, remove environmental threats to ground water, and cut fertilizer costs by as much as 50%.]
There seems to be a good amount of molasses being used on plants, including in most commercial organic fertilizer mixes.
