In the UK countryside why are some grazing fields ridged,?

Question

i mean the field looks wavy like corrugated

Answer 1

I live in the city, so at a guess I would say it has something to do with irrigation.

Answer 2

It sounds as if it may have been plowed at some point and the plowing was done so as to reduce run off and erosion.

Answer 3

Maybe it was once an ocean floor.

Answer 4

Many crops are grown in rows.

So various equipment is used to make furrows to plant and irrigate those crops.

Answer 5

When you say ridged, I'm not sure if you mean an apex in the centre for drainage or the plough lines from pre tractor crop growing.

Plough lines are like a car doing a hand break turn and all the soil being piled up on the corner. Just happened a few hundred times very slowly :0)

Work out where the rain drains and and it explains itself.

Edit:

That's a plough line from a horse pulled plough, it's the edge of the plough blade pushing the soil up into a heap like a car turning and the wheels throwing everything in one direction. If you look they always go with the gradient never across. You plough up and down a slope so water can drain.
