Since, various agricultural policies cannot be studied in vitro, the potential impact of policies before, during or after the policy implementation, must be analyzed using mathematical programming models (MP). In this regard, the consequences of the increase in the price of fertilizers and policies affecting that at farmland in Iran, Yazd province, Abarkouh County Using the Positive Mathematical Programming Model (PMP) were studied. Data were collected through questionnaires. Environmental indicators were also calculated and the environmental impacts ofthe removal of fertilizer subsidies on agricultural subsectors within several scenarios were analyzed. The results show that if with the increase in prices of fertilizers, direct payment policy will be also applied,further reduce in the use of chemical fertilizers Can be held.Based on the results of these study the farmers in the area, According to income level and the size of their farm exhibited different responses to policies.
