Zone4 is less intensive arable. Farmers in this zone apply 7-years crop rotation:1 year of rye,1 year of oats ,3 years of pasture ,and 1 year of fallow.the products are rye,cheese ,butter and livestock . since cheese and butter do nit perish quickly as the milk, they can produc some distance away from the market.
