      I am from Wisconsin (Milwaukee), and I have never seen the topography quite this way... but I can explain it. Farmers in the rolling hillside need to follow the contours of their land, so farming in straight rows is both not possible and not good for the soil. The Southwestern part of the state is incredibly rich in nutrients but the topography is convoluted. Notice the striped effect? they alternate lines of crops for erosion control in the hills. For a frame of reference, the "fall line" of the hills are perpendicular to the row of crops, so you can get an idea as to how the water would drain down by drawing arrows at 90 degrees to the lines. The "box" effect is due to the county roads between farms. Each farm grows different crops which is why the patterns and colors do not seem to continue outside of their respective squares. Its quite an optical illusion. Sweet photo of a wonderful part of the country.

      As implied by Matt's remarks, called contour farming.
