It's been some time that I think a seedball machine will save me a huge lot of work.
In searching for suitable , simple ways of making one I hit on "Star Rollers"
they are used by pyrotech guys.

If a small group got together one could make a lot of seedballs.
I could sow Veg "wild" to resemble Fukuoka's or Sepp's
also sow cover crops, leguminous seeds after cutting the cover crops.
It would have a lot of use. One could make enough balls to seed an acre in a day !!
Theres even videos of "tyre star roller" - a bit more complex
