Abstract: We provide a comprehensive theoretical analysis of private and social optimum in dairy production when society accounts for greenhouse gas emissions and nutrient runoff to waterways. The private farmer maximizes revenue from milk production by choosing herd size, diet, fertilization and land allocation between crops. Changes in the diet impact milk production, manure composition, and land allocation between crops. A critical radius emerges for the choices of crops and fertilizer type (mineral and manure); it is independent of the chosen crops in the private optimum but not in the social optimum. Fertilizer intensity is higher in the manure fertilized fields than in the fields where mineral fertilizer is used. Moreover, manure application rate decreases in distance to the farm centre. In contrast to what has generally been thought, the socially optimal fertilizer application follows the same spatial pattern than the private fertilization but at a lower level of intensity. A simulation model applied to the Finnish agriculture is used to further examine the features of the model. Acknowledgement : The work presented is part of the BONUS GO4BALTIC project: .
