美国商业航空业的兴趣以及美国海军和空军对使用可再生燃料的承诺激发了人们对识别和开发可再生航空燃料作物的兴趣。对与土地利用变化相关的温室气体排放以及将用于粮食生产的土地转变为燃料原料生产的担忧，鼓励了通过各种双季种植策略强化当前主要种植制度的概念。亚麻荠 (Camelina sativa L.) 和田间油菜 (Thlaspi arvense L.) 是两种冬季油料作物，有可能整合到玉米 (Zea mays L.)-大豆 [(Glycine max (L.) Merr.] 种植系统中，这是美国玉米种植带的主要种植系统。除了为可再生航空燃料生产提供原料外，将这些作物整合到玉米-大豆种植系统中还可能提供其中一些包括保护土壤免受风和水侵蚀、土壤有机碳 (SOC) 固存、通过减少硝酸盐改善水质以及为传粉媒介提供食物来源。然而，将这些作物纳入玉米-大豆种植系统也可能存在局限性，例如后续大豆作物的产量可能会减少。本综述确定并讨论了将亚麻荠或田间田芥纳入玉米-大豆种植系统的一些主要好处和限制，并确定了潜在的一般领域。美国玉米带的采用。
Interest from the US commercial aviation industry and commitments established by the US Navy and Air Force to use renewable fuels has spurred interest in identifying and developing crops for renewable aviation fuel. Concern regarding greenhouse gas emissions associated with land‐use change and shifting land grown for food to feedstock production for fuel has encouraged the concept of intensifying current prominent cropping systems through various double cropping strategies. Camelina (Camelina sativa L.) and field pennycress (Thlaspi arvense L.) are two winter oilseed crops that could potentially be integrated into the corn (Zea mays L.)–soybean [(Glycine max (L.) Merr.] cropping system, which is the prominent cropping system in the US Corn Belt. In addition to providing a feedstock for renewable aviation fuel production, integrating these crops into corn–soybean cropping systems could also potentially provide a range of ecosystem services. Some of these include soil protection from wind and water erosion, soil organic C (SOC) sequestration, water quality improvement through nitrate reduction, and a food source for pollinators. However, integration of these crops into corn–soybean cropping systems also carries possible limitations, such as potential yield reductions of the subsequent soybean crop. This review identifies and discusses some of the key benefits and constraints of integrating camelina or field pennycress into corn–soybean cropping systems and identifies generalized areas for potential adoption in the US Corn Belt.
