These first two photo's show after a month or two , it does the same thing to soil , often anyway , it darkens the soil , While earth tone color does not often define as anything , it is interesting
This last photo shows the green jug in back of photo , turning darker ,,
The interesting about this seems to be , this algae , is not dead when it turns darker , While if used this way , full strength , it can brown spot plants,
The great benefit of this is : it seems to grow anaerobic (without extra air) Yes I know most of you know that ,) What this is about is when your soil begins to compact , this algae keeps growing without air( right back through those nasty old dirt clods that bounce your spade or shovel) , (city water kills this effect , stay with rain or filtered water ) Yes indeed, Right back to the surface , through those packed dirt clods , etc it fights soil compaction without any thing else being done , cool according to me !
All it has to be is kept moist under mulch etc ,,,
