Nitrogen nitrate total as n
WebNitrogen is a chemical element with the symbol N, the atomic number of 7, and the atomic mass of 14. It can occur in a diatomic molecular form (N 2) as a colorless gas and be a part of a liquid or solid compound. About 78% of the Earth's atmosphere is composed of a gaseous form of nitrogen making it the most abundant uncombined element. WebSupporting: 2, Mentioning: 4 - Potato is often produced by adopting high nitrogen (N) external inputs to maximize its yield, although the possible agronomic and qualitative benefits of a N over-fertilization to the crop are scarcely demonstrated. Therefore, our aim was to determine, over two years, the effect of three N fertilization rates (0, 140 and 280 …
