If its sandy soil it will drain quickly and nutrients are leached out so you
can pile in now and keep piling on add infinitum as much muck and compost as
you can get/make ......or.you will find in a years time it will be exactly
same as today

Double digging ground that will eventually be borders, I have access to as
much well rotted [1] horse manure as i like. Two questions, How much
should
I add? and At what depth should it be added? I know rotovating it in would
be best, but this aint an opption, just a layer added at some
point........Its hard enough work to start with!

I had been thinking of a 2" layer about 6" from the top.

The ground, I think is a slightly sany loam, that has been compacted to
near
a concrete state.

[1] The Manure is black and the straw in most is unrecognisable, their is
little to no smell

How quickly can I plant into this, providing I make sure no manure is
touching the new root ball.
