thanx 2 all for your replies upto date . inow have a good idea on what to do .im going to BAN THE ROUND UP IDEA ! That seems to make very good sense. im going to use my plastic sheet to cover manure that im going to spread [ive allready got the sheet 100square metres] then start on a little bit at a time im only going to aim at getting less than half done at the moment it is 21 metres long by 6 metres wide in total so if i only aim at doing a bit ive got plenty to be going on with!!!!!!!!!! expect a lot more questions in the near future.
