Rye coltivation with seed balls

No plowing,
No weeding,
No fertilizing,
Rye has been sown very late, almost in the end of november.
Rye has been sown in the existing vegetation without cutting any grass.
With temperatures below 0 existing grasses have been died, so there was no need of any cutting.
 
Unique human action was sowing seed, be foolish in farming.
