Phosphorus budgets of intensively managed row crops at a long-term agroecosystem research site in the upper US Midwest

Phosphorus (P) budgets for cropping systems provide insights for keeping soil P at optimal levels for crops while avoiding excess inputs. We quantified 12 years of P inputs (fertilizer and atmospheric deposition) and outputs (harvest and leaching losses) for replicated maize (Zea mays L.)—soybean (Glycine max L.)—wheat (Triticum aestivum) crop rotations under conventional, no-till, reduced input, and biologically based (organic without compost or manure) management systems at the Kellogg Biological Station LTAR site in southwest Michigan. Conventional, no-till, and reduced input systems were fertilized between 13 and 50 kg P ha−1 depending on year. Soil test phosphorus (STP) was measured at 0- to 25-cm depth every autumn. Leached P was measured as dissolved P in the soil solution sampled beneath the rooting depth and combined with modeled percolation. Fertilization and harvest were the predominant P fluxes in the fertilized systems, whereas only harvest dominated P flux in the unfertili..., , , # Data from: Phosphorus budgets of intensively managed row crops at a long-term agroecosystem research site in the upper US Midwest Readme for data table (7 CSV data files), included in: Hussain et al (2025) titled “Phosphorus budgets of intensively managed row crops at a long-term agroecosystem research site in the upper US Midwest” for the publication in the Journal of Environmental Quality, [https://acsess.onlinelibrary.wiley.com/doi/pdf/10.1002/jeq2.70000](https://acsess.onlinelibrary.wiley.com/doi/pdf/10.1002/jeq2.70000) For further inquiries, please contact Mir Zaman Hussain ([[e-mail]](mailto:[e-mail]) or [[e-mail]](mailto:[e-mail])). 7 CSV data files: 1. nitrogen and phosphorus fertilization (1._Nitrogen_and_phosphorus_fertilization_no_terms.csv) 2. grain yield of maize, wheat, and soybean (2._Grain_yield_of_maize__wheat_and_soybean_no_terms.csv) 3. stover yield of wheat (3._stover_yield_of_wheat_no_terms.csv) 4. plant tissue p...,种植系统的磷（P）收支可为维持土壤磷处于作物生长最优水平提供参考，同时避免过量磷投入。本研究对密歇根州西南部凯洛格生物站长期农业生态研究（Long-Term Agroecosystem Research, LTAR）站点的重复设置玉米（Zea mays L.）-大豆（Glycine max L.）-小麦（Triticum aestivum）轮作试验系统，开展了为期12年的磷输入（化肥与大气沉降）与输出（收获与淋溶损失）量化分析，该系统涵盖常规耕作、免耕、减投入以及基于生物调控的管理模式（无堆肥或粪肥的有机种植体系）四种管理类型。常规耕作、免耕和减投入系统的年施肥量为13至50 kg P ha⁻¹，具体数值随年份有所调整。每年秋季均会在0至25厘米土层深度测定土壤有效磷（Soil Test Phosphorus, STP）。淋溶磷以根层下方土壤溶液中的溶解态磷进行测定，并结合模拟渗滤量进行核算。在施肥系统中，施肥与收获为主要的磷通量来源；而在未施肥系统中，仅收获主导磷通量…… # 数据来源：《美国中西部上游长期农业生态研究站点集约化管理行作作物的磷收支》 本数据表包含7个逗号分隔值（Comma-Separated Values, CSV）数据文件的说明文档，相关内容出自Hussain等人2025年发表于《环境质量杂志》的论文《美国中西部上游长期农业生态研究站点集约化管理行作作物的磷收支》，论文链接：https://acsess.onlinelibrary.wiley.com/doi/pdf/10.1002/jeq2.70000 如需进一步咨询，请联系Mir Zaman Hussain（邮箱：[e-mail] 或 [e-mail]）。 7个CSV数据文件分别为： 1. 氮磷施肥数据（1._Nitrogen_and_phosphorus_fertilization_no_terms.csv） 2. 玉米、小麦与大豆籽粒产量数据（2._Grain_yield_of_maize__wheat_and_soybean_no_terms.csv） 3. 小麦秸秆产量数据（3._stover_yield_of_wheat_no_terms.csv） 4. 植物组织磷……
