Undulating Field

This is a work in progress as I feel something is still missing with it, though I'm not sure what or how...

Desertion has its virtues
Upon the golden corn field
As the scarecrow backs away
Into the get away car.

Lone guardsman on the pole
Observing the yeast go down
And up and down again,
Pretending to be free.

The mindless wheat
Fulfills that which it sows
On the hard brownish land,
A stool to rest the splinter soles.

The crucified has vacated
The post no longer there;
Rot and decay dawdle
At the tall pillars of hay.

On the seasons press
And the agony recedes,
Tumbling down with the weed
Of a forsaken effigy.
