We keep the cows off the slurry grass for maybe 4 weeks, if it has been chucking it down with rain then 2-3 weeks is safe
We add an organic additive to the slurry before spreading it wich makes it break down quicker, this means animals can graze on it quicker than the defra guidlines
Slurry is worth alot more than people think, and although we are glad to get our slurry tower emptied, its not like we want to just give it away, slurry can continue to add benefits to the ground for a few weeks after applying it, so worth adds up
Also we paid a contract farmer (lives 7 mins away) to spread slurry from our tower onto our fields, after going away for the weekend and coming back to find he had been carting it back home to spread on his own fields!!!!!!

he did receive a bill later on for the slurry he put on his land as it was meant to go on ours!!!!
Spreading all of last year on crop ground we charged £30 per acre for the actual slurry but including labour, tractor hire, tanker hire and man hire it sort of comes to £60-£90 per acre, but this depends on how thick they want it, some want it on like muck and then plough it in, others want it like water and then graze it after a few weeks.
So as it was a favour and he isnt expecting money for the tractor hire etc, im sure £30-40 would do (or anything worth that)
Hope this helps
