Currently, environmental pollution and greenhouse gases emissions are both challenges of the human society that have attracted the attention of many countries, scientists and researchers. To control and reduce the environmental pollution, it is necessary to track the environmental impact during the production of the desired product. Therefore, the agricultural industry required an appropriate policy management to reduce the environmental impacts for the production process with less impacting. LCA approach specifies the environmental impact during the production of the interest product. In addition, corn, wheat and soybeans are among the top 10 products in the world. Therefore, producing these crops according to the type of production system, the rate of inputs consumption, and also the identified negative impact on environment during planting, are essential for the proper management of resources. The collected data were analyzed and the necessary information for the system input was obtained, the data was imported to the SimaPro software. According to the obtained results, the amount of acidification and photochemical oxidation indicators for wheat, corn and soybean were calculated to be 16.7, 14.9, 6.6 kg SO2 eq and 0.715, 0.634, 0.359 kg C2H4 eq, respectively. Therefore, the results showed that the maximum amount of acidities and photochemical oxidation were from wheat. Also, in another environmental indicators, the soybean product showed the maximum amounts. Finally, to reduce environment impacts of production, some solution has been provided for resource consumption management.
