Description

The article is based on research data collected from farmers and utilizes the theory of agricultural carbon footprint and life cycle assessment to quantitatively study the size and composition of the carbon footprint of the rice-wheat rotation system in the downstream area of the Yangtze River. Additionally, it further analyzes the factors that influence the carbon footprint. Users of this data set should apply it to assess the environmental impact of corn production in the Northwest (Linze, Zhangye). It is pertinent for LCA practitioners to consider the regional specificity of agricultural practices when modeling system boundaries and inventory flows. Attention should be given to the agricultural input and crop production systems detailed within the data set, including the use of chemical fertilizers and electricity. Users should also ensure they adhere to methodological standards of LCA and account for the complete life cycle of corn, from production to post-harvest treatments.

Technology

LCA method is used to evaluate the agricultural system of seed corn production, which takes the whole process of product treatment from input to final output as the research object to conduct quantitative analysis and comparison, so as to evaluate the environmental impact of seed corn production [13]. In this paper, the mass of seed corn 1 t is used as the functional unit. The boundary of the system starts from the production of fertilizer and electricity, and ends from the output of agricultural products and pollutants in the crop planting process. In other words, there are two production systems, namely the agricultural material production system and the crop production system
