英文文献：Implications Of Remote Sensing Imagery And Crop Rotation For Nitrogen Management In Sugar Beet Production-遥感图像和作物轮作对甜菜生产中氮管理的影响

英文文献摘要：
Adoption of new technologies, such as remote sensing, is slowed by such factors as high monetary and/or human capital costs and uncertainty about their value. This analysis explores the impact on nitrogen fertilizer use and efficiency and net returns among sugar beet producers in the Red River Valley from using remote sensing technologies and crop rotation for nitrogen management. The study found that cropping patterns had a significant impact on nitrogen use and net returns, but that most decision tools used for nitrogen management had little influence. The impact of using remotely sensed images for nitrogen management in sugar beets was not statistically significant.
由于货币和(或)人力资本成本高以及对其价值不确定等因素，诸如遥感等新技术的采用速度减慢。本分析探讨了利用遥感技术和作物轮作进行氮肥管理对红河流域甜菜生产者氮肥使用、效率和净收益的影响。研究发现，种植方式对氮肥使用和净收益有显著影响，但大多数用于氮肥管理的决策工具影响不大。使用遥感图像进行甜菜氮管理的影响在统计学上不显著。
