We live only 50 miles or so from NYC, but it's far enough away to be quite rural in some respects. Farming is still prevalent, especially in the rich, black dirt region that is so distinctive for its' onion growing. Yet other crops are common here as well, and other parts of Orange County are very active agriculturally. I don't know what crop is being protected here by the plastic sheeting, but it looks very labor intensive. The sheeting continued for acres and acres, and I'm sure the young plants will thrive with this kind of attention. The other field is fallow, I assume, and the dead plants will help renew the earth here.
