The rhymes mostly work, but the meter gets hammered out of shape in a few places. I like the mood this strikes, and as far as I can tell, the speaker enjoys reading but gets interrupted. The only specific interruption mentioned is music from passing cars, though it's not clear whether the speaker dislikes all the music. It had a similar feel to me as "The Raven," though it's structured differently.

Perhaps the author has personal experience with this? I suspect a British author, as an American one wouldn't rhyme grain/again. Though I do wonder what the title has to do with it. Nothing in the poem speaks to something unique to farming, I suppose unless the specific grass is wheat or oats or some such. I do like the way there's almost an additional rhyme: stain/again works (inasmuch as grain/again does, depending on nationality), and nascent/grain is kind of close to one.

So it's just a list of anagrams for the prompt? I mean... it's a thing, but I don't know what a reader's going to get out of it as a poem.

And the same thing again. I assume it's the same author, and then my question is: why are these two separate poems? If there was a purpose in differentiating them, I can't tell.
