A good friend of ours turned up with a trailer full of fresh horse sh1//!t at our plot. Luckily I had managed to procure a free builders wheelbarrow from a free online forum.
We borrowed another barrow from a fellow plot holder and heaped the manure up into a mound at the end of the plot. We then covered the heap with tarp to keep out the rain.
We can’t use it until it rots down so we have been making pallet composts and adding in the fresh stuff with layers of greenery and grass cuttings (to add nitrogen).
It should be good to go in a year or two, you have to be patient in this game…
