This study investigates the energy consumption and greenhouse gas emissions from fertilizer use for corn, cotton and soybean production in Turkey. For corn and cotton cultivation 403.33 kg NPK is applied before planting per hectare, 238.33 kg AN and 238.33 kg urea after planting. For soybean production 201.66 kg DAP before planting per hectare, 135.83 kg AN and 135.83 kg urea after planting are applied. For corn cultivation, 11,991.65 MJ fertilizer energy is consumed per hectare in Turkey. However 8973.56 MJ and 6,452.94 MI fertilizer energy is consumed per hectares in cotton and soybean production, respectively. The total GHG emissions from fertilizer application are 2,603.7 kg CO2-eq, 1,949.13 kg CO2-eq and 1,523.22 kg CO2-eq per hectares, respectively.
