Potential of extensification of European agriculture for a more sustainable food system ; the case for nitrogen and livestock

2.1 Impacts of low input organic dairy farming in the Netherlands on milk yields and farm income Provisional data from two farms is encouraging but are only indicative. Both farms represent a larger group of about 50 dairy farmers in the Netherlands (0.3% of total farms) that combine intensive grazing and minimal use of feed concentrates and silage maize. These dairy farmers apply rapid rotation grazing, or strip grazing, which typically involves a wagon-wheel arrangement of fences. In the Dutch examples fences are moved up to six times per day. Dairy cattle is consecutively confined no longer than 30 days per year (in winter).
