horse poop is an ideal soil conditioner and fertiliser. If you are
prepared
to wait until autumn to plant a garden mixing horse poop in with the
soil,
or even simply sheet mulching it on top of the soil, will improve
the
quality surprisingly quickly. If you are worrid about seeds coming
up cover
the poop with black plastic (staked down) or something like old wool
based
carpet or hessian carpet underlay. Any weeds coming up will either
get
scorched to death by the black plastic or die under the carpet due
to a lack
of sunlight. In autumn you will have really nice crumbly soil, good
humus
and likely a stack or worms. The soil will be much better at
retaining
moisture and be choka full of nutrients. Whilst horse poop is low is
nutrients on a pound per pound basis with synthetic fertilisers in
bulk it
is perfect.

I'd agree with most of this post but in my experieince, I've not found
that horse poo has many weeds and I wouldn't recommend the plastic
sterilisation technique. Yes, the odd weed does come up, but given
how stunning horse poop is for improving the soil, the few weeds
produced come out very easily. The disadvantage of the plastic
sterilisation trick is that it stops the soil microbes going to work
and improving your soil.

I use copious quantities of horse poop and in your situation, I'd
recommend mixing the sandy soil with a good quantity of poop add
generous amounts of Dynamic Lifter and then water well and then
slather the whole top of the area with as much horse poop as you can
lay your hands on. This top layer is just to protect the lower layer
and let the microflora of the soil go to work and can be sacrificed
later if it drys out and looks like it'll never hold water again. I
also wouldn't plant now but would wait till Autumn.
