| The aim of this paper is to identify optional ways of preventing NO3-levels from rising within Croatian farming systems, and the implications from the viewpoint of the manager. More specifically, the purpose is to 1) Determine whether Croatian farmers exceed profit maximising levels of N-fertilizer use in maize cultivation, and its possible influence on NO3 N-levels. 2) To estimate the marginal abatement cost (MAC), at the farm level, of reducing NO3 N leaching through the following instruments: a tax on optimal N-doses, a product tax and an N-fertiliser quota and a requirement for all instruments to correspond to the same abatement level. Based on. N-response experiment from feld trial for maize N-response curves were estimated. A sample of 20... |
