项目摘要
Farmers in the United States (US) Corn Belt produce ~30% of the world’s corn and soybean, which depends on the use of fertilizers containing both nitrogen (N) and phosphorus (P). However, due to a lack of consistent and reliable information, these farmers tend to over-apply fertilizer. This practice directly affects farmers, as they are paying higher fertilizer costs than necessary, and negatively impacts environmental sustainability. Yet, farmers’ perceptions of nutrient management challenges vary widely as does their willingness to adopt novel nutrient management approaches. Working collaboratively with the Illinois Farm Bureau, the University of Illinois Extension, and engaging farmers directly through the these partnering organizations, the team of academic and community partners aims to build a smart and connected "Nutrient Management Community (NuMC)" to help farmers adopt effective and trusted nutrient management tools to address critical water quality issues stemming from nutrient runoff while reducing farm nutrient application costs. The project is built on the premise of voluntary adoption of nutrient management practices and includes social science questions to assess the reasons and strategies for encouraging adoption of voluntary “best practices.”Enabling farmers to manage N and P with greater precision is needed to increase farmer profitability and decrease off-farm losses of nutrients, which can compromise water resources. The objective of this research is to develop science-driven recommendations on N and P management that can be tailored to different farmers’ needs, focusing on the heart of the US Corn Belt: Illinois. This work has three objectives: (1) identify major constraints on how Illinois farmers manage N and P management, and determine to what extent these constraints vary among farmers; (2) determine how much N and P are stocked in soils across a diversity of Illinois farm (including through the use of soil sensors and satellite observations), and how this soil nutrient capital contributes to crop growth in order to model field-specific fertilizer needs; and (3) develop smart and connected technology solutions that enable constrained farmers to join a Nutrient Management Community (NuMC). This work will advance understanding of agricultural management by and for farming communities by providing insights on interrelated social science, biogeochemistry, and technology dynamics. The proposed approach will produce a community-based cyberinfrastructure that will address an urgent need: providing Illinois farmers direct access to high-quality and unbiased information on management nutrients.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
美国 (US) 玉米种植带的农民生产全球约 30% 的玉米和大豆,这取决于使用含氮 (N) 和磷 (P) 的肥料,但由于缺乏一致且可靠的肥料。据了解,这些农民往往会过度施肥,因为他们支付的肥料成本高于必要的成本,并对环境可持续性产生负面影响。然而,农民对养分管理挑战的看法差异很大,他们采用肥料的意愿也不同。新型营养管理学术和社区合作伙伴团队与伊利诺伊州农业局、伊利诺伊大学推广部合作,并通过这些合作组织直接让农民参与,旨在建立一个智能且互联的“养分管理社区(NuMC)”来帮助农民。采用有效且值得信赖的养分管理工具来解决养分径流引起的关键水质问题,同时降低农场养分施用成本。该项目建立在自愿采用养分管理实践的前提下,并包括评估其原因和策略的社会科学问题。鼓励采用需要使农民能够更精确地管理氮和磷,以提高农民的盈利能力并减少可能损害水资源的非农场养分。这项研究的目的是制定科学驱动的建议。针对不同农民需求的氮肥和磷肥管理,重点关注美国玉米种植带的核心:伊利诺伊州。这项工作有三个目标:(1) 确定伊利诺伊州农民如何管理氮肥和磷肥管理的主要限制因素,以及(2) 确定这些限制因素在农民之间的差异程度;确定伊利诺伊州各个农场的土壤中储存了多少氮和磷(包括通过使用土壤传感器和卫星观测),以及这些土壤养分资本如何促进作物生长,以便模拟特定田地的肥料需求; (3) 开发智能互联技术解决方案,使受限农民能够加入养分管理社区 (NuMC) 这项工作将通过提供对相关社会科学、生物地球化学和技术动态的见解,增进对农业社区的农业管理的理解。提议的方法将建立一个基于社区的网络基础设施,以满足迫切的需求:为伊利诺伊州农民提供直接获取有关营养物质管理的高质量和公正信息的机会。该奖项反映了 NSF 的法定使命,并通过使用基金会的智力优势进行评估,被认为值得支持以及更广泛的影响审查标准。
