The economic potential of precision nitrogen application with wheat based on plant sensing
研究了基于植物传感的精准施氮技术在冬小麦上的预期利润，发现其有潜力比传统非精准系统更盈利，但现有系统与传统系统大致持平。
Abstract Plant‐based precision nitrogen fertilizer application technologies have been developed as a way to predict and precisely meet nitrogen needs. Equipment necessary for precision application of nitrogen, based on sensing of growing wheat plants in late winter, is available commercially, but adoption has been slow. This article determines the expected profit from using a plant‐sensing system to determine winter wheat nitrogen requirements. We find that plant‐sensing systems have the potential to be more profitable than traditional nonprecise systems, but the existing system simulated was roughly breakeven with a traditional system.
