Hi dyzzypyxxy, Well I know Alfalfa has been used as a green manure for many years. Like certain clovers for their beneficial retention of nitrogen in the soil. The plants are turned under generally in the spring and allowed to rot giving the soil a burst in nitrogen and of course the decomposition of the plants themselves. Even plants like peas will fix nitrogen in the soil. I'm not sure about the use of the alfalfa to make compost tea, when it hasn't been composted, since the benefits are in what's left after the decomposition by beneficial microorganisms. I think the three way experiment sounds like a very good idea. I actually reminds me of the experiment with beans we did in school by placing them in the bottom of a series of boxes on on top of the other cutting holes to allow light in a different plant in each, just to see how well the bean plant would stretch up through each box towards the light. So I think you should try the experiment and take pictures as well to document the progress.
As far as my little Alocasia, it's limping along. The four plants have put out another leaf and each on is small and distorted, so I'm keeping a close eye on them. If worse comes to worse, I'll un-pot them all and put each into it's own pot and see if that makes a difference. Thanks for asking.
Good Growing Dyzz
