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

平衡维持安全营养食品的安全供应的需求，同时最大限度地减少作物生产过程中造成的环境影响，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这场战斗的一部分：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项目是斯托克布里奇技术中心、Manterra有限公司和克兰菲尔德大学之间的合作项目。它应用工程和传感器解决方案，卫星图像数据和独特的施肥技术，以帮助农民为他们的业务和我们所依赖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自动转向和作物根部附近土壤表面下的肥料注入。通过将肥料注入地下，与将肥料撒在土壤表面相比，可以降低氮肥释放的一氧化二氮气体的水平。

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.
