Tru-Nject: Proximal soil sensing based variable rate application of subsurface fertiliser injection in vegetable/ combinable crops

在保持安全的营养食品供应的需要之间保持平衡，同时将作物生产过程中造成的环境影响降至最低，这是一项需要复杂解决方案的挑战。了解农田土壤的变化只是战斗的一部分：精确管理这种变化以稳定作物产量，减少化肥投入是Tru-Nject系统的重点。Tru-Nject项目是斯托克桥技术中心、Manterra有限公司和克兰菲尔德大学的合作项目。它将工程和传感器解决方案与卫星图像数据和独特的肥料放置技术相结合，帮助农民为他们的业务和我们赖以生存的土地做出最佳决策。Tru-Nject提供了多种效率来源之间的协同作用：土壤数据、卫星数据、GPS自动导航和在作物根部附近的土壤表面下注入化肥。通过在地下注射化肥，与在土壤表面喷洒化肥相比，氮肥释放的一氧化二氮气体水平可能会降低。

Balancing the need to maintain a secure supply of safe nutritious food, whilst minimising environmental impacts caused during crop production, is a challenge requiring sophisticated solutions. Understanding variation in farmland soils is only part of the battle: precise management of that variation to stabilise crop yield, and reducing fertiliser inputs is the focus of the Tru-Nject system.The Tru-Nject project is a collaboration between Stockbridge Technology Centre, Manterra Ltd, and Cranfield University. It applies engineering and sensor solutions with satellite image data and unique fertiliser placement technology to assist farmers in making the best decisions for their business and the land on which we depend. Tru-Nject offers a synergy between multiple sources of efficiency: soil data, satellite data, GPS-autosteering and injection of fertiliser below the soil surface near the roots of a crop. By injecting fertiliser below ground, reduced levels of nitrous oxide gas released from nitrogen fertilisers may be attained, when compared with spreading fertiliser across the soil surface.
