What are the crops that are planted in a wave form in fields and why.?

Question

I have seen wave like crops on Google Earth in the area of Maghull, Liverpool

Answer 1

If your talking about the shape of the fields, it's for crop rotation and erosion control.

Answer 2

With contouring, you perform farming operations across the slope, following the shape, or contour, of the land.

From the air, contouring presents dramatic patterns on the land. But in terms of erosion control, the real drama takes place closer to earth.

The small furrows and ridges act like dams, trapping runoff water, sediment, nutrients, and pesticides, and directing them along graded crop rows to outlets such as grassed waterways or field borders.

The results, some say, are reductions in soil erosion up to 50 percent on gentle slopes when compared with up and down hill farming. On very steep slopes, the erosion reduction will be less—possibly as low as 10 percent.

Contouring also offers possible savings in fuel and reduced wear and tear on machinery and equipment. Some farmers report that it takes less power to farm across the slope than up and down hills.

Answer 3

What you are seeing are probably wheat fields, but could be any tall grass or small grain farms. When the wind blows across the fields and make "waves" in the wheat. They are not planted in waves, but just in a fairly solid stand. This is exactly what the song is talking about with "The amber waves of grain" This was wheat that was mature but still not harvested. If you looked at them recently it would be the green waves of grain. I haven't seen this on Google Earth but will look now, it must be a pretty sight.
