Brittany Shyne’s stunning documentary observes Black farmers in the American south over the course of seven years, and portrays the beauty and the hardships of working with the land. The black-and-white cinematography lends a visual sumptuousness to the rituals of harvest: we see giant machines extracting cotton buds from open bolls, leaving behind a whirl of white fluffs fluttering in the air. The painful legacy of slavery in the country means that the choreography of farm work is rich with poetic and political meaning. Owning land is more than an economic matter; it also allows for autonomy of labour and preservation of heritage, to be passed on to future generations.

Hardworking as the farmers are, however, systematic discrimination continues to hinder their financial security. While their white neighbours have easy access to federal support, Black farmers are faced with near-insurmountable red tape, resulting in much longer waiting times for funding. With the landslide effect of operational costs and taxes, many have had their land taken away from them. One particularly poignant sequence follows 89-year-old Carlie Williams, who has farmed since his teens, as he struggles to negotiate the price of prescription glasses. Most of the subjects in the documentary also hail from older generations; the implication is that, with all its precariousness, this line of work is no longer viable for younger people.

Still, this documentary is far from an elegy. The resilient community fight back, as they march to Washington to protest against the inadequacies of the Biden administration. Echoing the cycle of crop cultivation, Shyne’s film inhabits the seasons of life, bookended by images of a funeral and the open sky. This vanishing way of life is imbued with a dose of melancholy, yet hope still remains for a better harvest in the future.
