New allotment questions

Hi
 I have recently got an allotment which was very overgrown, my tree surgeon brother in law, kindly lent us a brush cutter, so all the weeds and brambles have been cut right down.
 My plan is to cover the best part if the allotment with silage sheeting over the winter, but I am hoping to plant a couple of fruit trees and bushes.

My first question is about a blackcurrant bush, which is the only thing I found under all the weeds. Im glad I have managed to find something, but wondered if it would survive if I move it to a different part of the plot, and the best way to do this?

My second question concerns horse manure. I have a friend with a stud farm, so can get plenty of it. The question is do I put it all onto a compost heap and let it rot down to use later? Some of it is fairly well rotted already; or should I put some down on the ground to be covered with silage sheeting and will it rot down,under that?
Any tips and/or suggestions gratefully received, as I have very limited fruit & veg growing experience.

Thank-you, I will do that then

And don't forget to take lots of photographs so you can look back and see the improvement when you hit the wall and think that you are not making headway fast enough - The Diaries on here are a great resource for that and for getting feedback as you go.

Good luck and best wishes! 
If I could go back and start again on my plot, I would glyphosate the lot and then go organic once the ground elder, creeping buttercup, docks, dandelions nettles and brambles were dead.  Failing that I would cover half the plot with the thickest layer of manure I could get, then cover it with black plastic for as long as possible, ideally a year, and repeat it on the other half the next year.  When you peel the plastic back you will have the most wonderful rich tilth that the worms have made for you.  If you are desperate for a crop and the weeds aren't too bad you can plant potatoes or courgettes through holes in the plastic. 

Again check with your allotment committee if either of these approaches ar against the rules first!

Digging the plot over and removing every vestige of weed roots is only OK if you have vast amounts of spare time and energy.

It's taken me two years to dig over and remove all the heavy duty weeds from my overgrown plot but I'm chasing less weeds than my neighbours who crashed on and rotovated.
