Hi Charles, thanks for the reply.
Just to clarify, the reason I am asking is because I have calculated that I need to be buying in the region of 4,000 litres of compost – from my research, I have found the price for buying this quantity of organic compost seems to range between approx £250 to £800 – that is quite a vast price range. It is also a lot of money to spend so my preference is to source a product that is tried and tested – I don’t have the experience, having only ever grown a small handful of vegetables in pots up to now. From what I have read through the forums and the books, people have had varying degrees of success with different composts.
So my question was not asking anything in-depth about composts – more just if there was any recommendations towards certain makes/companies.
On a different point, I currently compost my own horses manure. I have now fostered a rescue from the RSPCA but this pony has an extremely high worm count and so have had to put him on a cocktail of different chemical wormers to address the problem – I have avoided using this manure on my compost heap – are you aware if there are any implications of using manure on a compost heap from a horse that is being wormed??
