Does anyone have experience in using airborne or other algae as a garden fertilizer? They seem to grow in ever clear water if left standing long enough. I've seem thick coverings on stagnant ponds, growing with no attention at all.
The Aztecs used this technique with human manure and refuse as a substrate. About 30 yrs ago, I recall a student developing a mixture of bluegreen algae which could be permanently applied to fields, but this formula was bought up by a fertilizer company.
A search of the internet yielded mostly algae as a nuisence in watergardens, fishtanks etc. It seems like a great potential is being missed here.
I used it this year.When I clean the dirty green with algae backwash sand from the swimming pool filter.I have grown sweet potatoes all my life,but this years crop ways huge. Jack
