Planting is always a challenging process, but planting cover crops can take that challenge to the next level with different seed shapes, sizes and densities. Each type of cover crop requires that the planter be calibrated differently, and multi-species mixes make it even more puzzling to find the best calibration. Whether you use a drill or a planter can also impact your approach. Steve Groff, Pennsylvania cover crop expert, shares some different methods for calibrating drills and planters to prepare for planting cover crops. (Courtesy of Cover Crop Innovators)
