Description

This study was conducted in Gaomi City, Shandong Province, which is located in Huang-Huai-hai Plain, the core area of winter wheat-summer maize rotation in China. The research was carried out in the form of a questionnaire survey, and a total of 56 farmers who operated wheat-maize rotation were interviewed. The contents of the questionnaire include input and output in the process of food production: (1) food output; (2) agricultural inputs such as seeds, fertilizers, herbicides, fungicides and insecticides; (3) Energy consumption of agricultural machinery, including fuel consumption in the process of sowing, farming and grain transportation; (4) irrigation energy consumption, etc Users of this data set should consider the limitations in the assessment of soil carbon change due to the variability of soil carbon baselines among different farmers and their management practices, as this was not included in the carbon accounting. The data should be applied cautiously when comparing to other regions or agricultural systems with different soil management techniques or when integrating soil carbon sequestration factors. The methodological guidance provided by the '2006 IPCC National Greenhouse Gas Inventory Guidelines' and 'ISO/DIS 14067' should be followed to ensure accurate greenhouse gas emission accounting. Users should also note that the functional unit is based on both unit area and unit yield, which may influence the interpretation of the carbon footprint data.

Technology

The study calculated the greenhouse gas emissions from the cradle to the door of the grain production process. The boundary of the accounting system includes: greenhouse gas emissions from agricultural inputs (such as seeds, agricultural medicines, fertilizers, etc.); Greenhouse gas emissions from the use of agricultural machinery (tillage, sowing, harvesting, food transportation, etc.); Field N2O emission caused by fertilizer application; Irrigation energy consumption, greenhouse gas emissions, etc. (Figure 1)
