The NUTRI-CHECK NETwork to maximise site-specific precision in managing the nutrition of European arable crops.

欧洲面临着巨大而紧迫的挑战，即提高作物产量，同时减少合成肥料的使用和养分损失。该提案旨在建立一个自我维持、多行为体的专题网络，称为“NUTRI-BARNET”，在整个欧洲范围内建立农场一级采用最佳实地养分管理做法。在九个国家，农民的作物营养俱乐部（CNC）将确定和分享他们对作物营养的不确定性的性质，他们的挑战和改变的障碍。决策系统和营养工具（包括商业产品、服务和最新研究成果）将由来自欧洲各地的国家专家（包括主要农民）汇集到一个共同的在线NUTRI-BERNET平台上。然后，CNCs将评估从工具箱中选择的新协议和工具的有效性，以应对其主要挑战。在那里，他们将共同创造和采用农场和田间特定的“管理措施”方法，以解决他们的作物营养挑战。农民和专家对协议和工具的评估将涉及其易用性、可信度、成本和收益。初步和最后评价将在整个网络中共享，以确定“最佳做法”，并将通过与其他相关专题网络和EIP-AGRI的联络等方式加以展示和广泛传播。工具箱和最佳实践将在欧盟农业手册上永久保存。广泛采用“措施管理”或“检查改变”的作物营养方法将提高养分循环和作物生产力，同时减少整个欧洲的合成肥料使用和养分损失。

Europe faces huge and urgent challenges of increasing crop productivity whilst reducing use of synthetic fertilisers and nutrient losses. This proposal is to establish a self-sustaining, multi-actor, Thematic Network called “NUTRI-CHECK NET” that builds farm-level adoption of best field-specific nutrient management practices across Europe. In nine countries farmers’ Crop Nutrition Clubs (CNC) will identify and share the nature of their uncertainties about crop nutrition, their challenges and barriers to change. Decision-systems and nutrition tools (including commercial products, services, and recent research outputs) will be assembled by national experts from across Europe, including leading farmers, into a common online NUTRI-CHECK NET platform. CNCs will then evaluate effectiveness of new protocols and tools selected from the a toolbox to meet their main challenges. Thence they will co-create and adopt farm- and field specific ‘measure-to-manage’ approaches that address their crop nutrition challenge(s). Evaluations of protocols and tools by farmers and experts will address their ease of use, trustworthiness, costs, and benefits. Initial and final evaluations will be shared across the Network to define ‘best practices’, which will be demonstrated and disseminated widely, including through liaison with other relevant Thematic Networks and EIP-AGRI. The toolbox and best practices will be held accessible and improvable in perpetua on EU FarmBook. Widespread adoption of ‘measure-to-manage’ or ‘check-to-change’ approaches to crop nutrition will enhance nutrient recycling and crop productivity, whilst reducing synthetic fertiliser use and nutrient losses across Europe.
