Nitrogen (N 2) Nitrogen is a chemical element that has the symbol N and atomic number 7 and atomic mass 14.00674µ. Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78% by volume of Earth's atmosphere. Many industrially important compounds, such as ammonia, nitric acid ...
به خواندن ادامه دهیدNitrogen fertilizer is the major production input for grain crops other than grain legumes. High use of N fertilizer in crop production results in a large C footprint for grains ( Gan et al., 2011c ). In some high N-using field crops, the C footprint is a function of the N rate applied to the crop ( Gan et al., 2011a ).
