Agricultural activities are major sources of nitrous oxide (N2O), which is a greenhouse gas. Current technology used to quantify the emission of N2O from fertilizer application in agricultural fields is complex and very expensive. Agrium, a fertilizer company, has developed an innovative polymer-coated urea nitrogen fertilizer, Environmentally Smart Nitrogen (ESN), which meters the release of nitrogen based on soil temperature and moisture. The fertilizer has improved crop production efficiency compared to a conventional urea fertilizer. Agrium considers that a real-time, hand-held system capable of monitoring the emission of N2O in agricultural fields under a variety of soil and climate conditions will increase the adoption and development of controlled-released nitrogen products. A real-time monitoring system would provide an accurate measurement of the concentration and flux of the emitted gas. Based on these measurements, the company can pursue a strategy of reformulating its products to reduce N2O emissions and/or change its instructions for applying fertilizer based on soil and climate conditions. With an accurate method for measuring emissions, the company can help Canada meet its goal of reducing greenhouse gas emissions and potentially increase its market share.

农业活动是一氧化二氮（N2 O）的主要来源，这是一种温室气体。目前用于量化农业领域化肥施用中N2 O排放的技术复杂且非常昂贵。Agrium是一家肥料公司，开发了一种创新的聚合物包膜尿素氮肥，即环境智能氮肥（ESN），它可以根据土壤温度和湿度测量氮的释放。与常规尿素肥料相比，该肥料提高了作物生产效率。Agrium认为，能够在各种土壤和气候条件下监测农田N2 O排放的实时手持系统将增加控释氮产品的采用和开发。实时监测系统将提供排放气体浓度和流量的准确测量。根据这些测量结果，该公司可以采取重新配制产品的战略，以减少N2 O排放和/或根据土壤和气候条件改变施肥说明。通过精确的排放测量方法，该公司可以帮助加拿大实现减少温室气体排放的目标，并有可能增加其市场份额。
