This drawing is a sketch with reed-pen for his famous painting of the same title. Van Gogh painted a series of paintings about wheat fields, he used that to express his spiritual beliefs, connection to the nature and appreciation of working people.

Van Gogh used nature for inspiration, preferring that to abstract studies from imagination. He wrote that rather than making abstract studies:

I am getting well acquainted with nature. I exaggerate, sometimes I make change in motif; but for all that, I do not invent the whole picture; on the contrary, I find it already in nature, only it must be disentangled."
