Farmland conversion and landfill sites

[ijmorlan]

…Also, many farmers don't rotate crops.  I too rent out land and they have been doing soybeans for 10 years straight with no issue and high yields...

Crop rotation is not about the next 10 years, but about the next several centuries at least. That they’ve repeated the same crop for 10 years doesn’t even begin to prove that it’s OK not to rotate.

(not a farmer; it may be fine not to rotate, I don’t know; but I do know that 10 years isn’t enough to establish validity of a farming practice related to soil quality)
