Somebody goofed!

In the scene where the airplane crashes, the house and barn are badly damaged, but the surrounding pasture looks a prestine green, without any torn up earth or bomb craters. Similarly, when Schofield runs across 'no-mans-land' in front of the trenches, bombs rain down, and create craters, but there are no old craters from previous attacks (?) Where he is running looks as well-manacured as NFL astroturf! Also, directly in front of these trenches, there are no coils of defensive barb wire (?)

The director could be forgiven for one blunder, but three are a bit too much to 'suspend my disbelief' !
