Sounds like the plan is to use pigs to dig drainage swales in a gently sloping, waterlogged area. Does that sum it up?
The reason why it is waterlogged is the huge amounts of rain falling here, combined with the compacted soil left after the heavy cattle from the previous farmer.
It will be for next year, but probably worth a shot.
Not sure if these would be proper swales at this point but I'll leave it up to someone else to come up with a better name.
I am almost sure they should not be called swales, as their function is quite the opposite, but will leave it to the native speakers to come up with a name...
