Currently, there are 13.9 million hectares of loblolly pine (Pinus taeda L.) in the Southern United States. Reforested hectares could be used for intercropping oilseed crops such as carinata (Brassica carinata) and white lupin (Lupinus albus L.). The oil obtained from these crops could be used for bio-jet fuel production to reduce the carbon footprint of the aviation sector. This study determines the profitability for three scenarios: loblolly pine with no intercropping (baseline), loblolly pine with carinata (once every three years), and loblolly pine with carinata and white lupin rotated annually. We ascertained the land expectation value (LEV) for three site indices of 15.3 m, 18.3 m, and 21.3 m. Carinata and white lupin were planted during the initial eight, seven, and six years for site indices 15.3 m, 18.3 m, and 21.3 m, respectively. Sensitivity and risk analyses were undertaken for determining the influence of input variables on LEVs and the probability of loss for intercropping production systems relative to a baseline production system, respectively. For site index 21.3 m, the LEV of loblolly pine with no intercropping was $2816/ha at a 21-years rotation period. Intercropping with carinata only and both carinata and white lupin yielded LEVs of $3346/ha and $3607/ha at a 21-years rotation period, respectively. The LEVs of production systems were sensitive to interest rate, price, and yield of carinata seeds. The intercropping approach had > 50% probability of being less profitable than loblolly pine alone in over half of the scenarios considered. Future research should focus on the impacts of intercropping on loblolly pine yield and adoption behavior of forest landowners.

目前，美国南部有1390万公顷的火炬松（Pinus taeda L.）。造林面积可用于套种油料作物，如卡里纳塔（Brassica carinata）和白羽扇豆（Lupinus albus）L.）。从这些作物中获得的石油可用于生产生物喷气燃料，以减少航空业的碳足迹。这项研究确定了三种情况下的获利能力：无间作的火炬松（基线），有carinata的火炬松（每三年一次）以及每年有carinata和白色羽扇豆的火炬松。我们确定了三个站点指数15.3 m，18.3 m和21.3 m的土地期望值（LEV）。在最初的八年，七年和六年中，种植了Carinata和白色羽扇豆，分别的立地指数为15.3 m，18.3 m和21.3 m。进行了敏感性和风险分析，以确定输入变量对LEV的影响以及间作生产系统相对于基准生产系统的损失概率。对于站点索引21.3 m，在21年的轮换期内，无间作的火炬松LEV为$ 2816 / ha。在仅21年的轮作期间，仅与Carinata间作，Carinata和白色羽扇豆间作的LEV分别为$ 3346 / ha和$ 3607 / ha。生产系统的LEV对Carinata种子的利率，价格和产量敏感。在考虑的一半以上情景中，套作方法比单独的火炬松获利的可能性要高50％以上。未来的研究应着眼于间作对油松的产量和林地所有者的收养行为的影响。生产系统的LEV对Carinata种子的利率，价格和产量敏感。在考虑的一半以上情景中，套作方法比单独的火炬松获利的可能性要高50％以上。未来的研究应着眼于间作对油松的产量和林地所有者的收养行为的影响。生产系统的LEV对Carinata种子的利率，价格和产量敏感。在考虑的一半以上情景中，套作方法比单独的火炬松获利的可能性要高50％以上。未来的研究应着眼于间作对油松的产量和林地所有者的收养行为的影响。
