Greetings everyone on this list, I am a newcomer and I find your
messages very interesting and useful too.
I was browsing through the archives seeking more seedball
informations, found various messages mentioning several layers with
Reading them two ideas popped into me, they-re probably stupid but
I'll let you be the judge.
1. The first idea is about gel. I bought from a specialised shop a
tiny envelope with only 5 grams of dry gel soil. It looks like dust
and comes in various colours. If put into water for a few hours, it
will inflate by absorbing 80-100 times its own weight of watter.
And can be used directly as a coloured soil for apparment flowers.
And keeps moist for several days, one can even leave the house for a
couple of weeks and the plants wont dry.
So the idea is to use any kind of dried gelatine, (not necessarly the
same as I described above) when making seedballs. Inflated by the
first rain it should hold water for the seed a few more days after the
soil arround has eventually dried.
And natural gelatin (like from animal bones and algae) is protein
based that means they are biodegradable and should give some nitrates too.
2.The second idea is about a natural aerial spreading of seeds - by
birds. Not too usefull for a small farm but might be efficient for
spreading seeds across a large area of desertified land.
It should work like this: make a two layer seedball.
The first layer must be very resistant - both chemically and
mechanically BUT biodegradable in a couple of weeks.
(celulose plastics mabe?)
The second layer should be starch based or any other food local birds
The whole point is that instead of spreading balls by airplane just
leave several feeders for the birds in the area and let them spread
the seeds as they naturally do since the begining of time. We just
give them the seeds we want them to spread. If it is a dry season let
some water available too, to attract birds from a wider area.
And the birds will happily provide a third layer - the fertiliser.
