Planting cover crops enhances the soil’s ability to function as a nutrient recycler. Penn State’s Dr. Sjoerd Dulker talks about how dairy farmers in his state are using cover crops to improve their business – without regulations or subsidies.
Dr. Sjoerd Duiker is an Associate Professor of Soil Management and Applied Soil Physics at Penn State University. After studying Tropical Crop Science for his Master's degree at Wageningen Agricultural University in the Netherlands, Dr. Duiker earned his Ph.D. in soil sciences from Ohio State University in 2000.
As an agronomist, Dr. Duiker works closely with local farmers to improve the sustainability and yields of their farms through better management practices. One of Dr. Duiker's main research interests is on how the use of no-till agriculture and cover crops improves soil quality on farms.
