University of New Hampshire researchers have found that using black tarps and cover crops successfully suppressed weeds in an organic vegetable system, allowing scientists to forgo tilling, which can have deleterious effects on soil.
The research was conducted at the Woodman Horticultural Research Farm, a facility of the NH Agricultural Experiment Station, by Seamus Wolfe, a sustainable agriculture and food systems major, Dr. Richard Smith, associate professor of agroecology, Natalie Lounsbury, a doctoral student in agroecology, and Nick Warren, manager of the agroecology lab.
