主要研究 今天

美国农业部 宣布5美元.拨款500万 通过 农业和食品研究倡议 (AFRI)支持创新农业生产系统的研究, including a project by University of New Hampshire researchers who will investigate ways to adapt cropping systems for increasingly variable weather. 联合国大学项目由 丰富的史密斯他是自然资源与环境学系的教授 娜塔莉·朗伯里, 农业部的研究助理教授, 营养, 食物系统, will focus on how alternative crop row orientation 和 spacing strategies affect the amount of light or solar radiation plants can absorb 和 how these strategies can be combined with innovative cover cropping approaches like interseeding 改善土壤水分动态，抑制杂草，促进土壤健康.

这项研究将解决农民面临的与气候变化相关的挑战， 例如降水变化和杂草压力增加. 在东北部, extreme precipitation events have increased by 71 percent from the mid-1990s to the 2010s, 增加了夏季干旱和过度潮湿的风险. 预计会出现更高的温度和更高的二氧化碳浓度 增加杂草竞争力，降低除草剂药效，进一步强调了综合杂草管理的必要性. 除了将在新罕布什尔进行的研究, the 主要研究 team will work with researchers at North Carolina State University to leverage an extensive national on-farm dataset from the 精准可持续农业网络 确定行向对作物产量的影响, 土壤水分 和 weed suppression across different environmental conditions 和 under different cover crop management.

“It's crucial to underst和 how we can adapt our farming practices to mitigate the impacts of climate change,史密斯说。, 一个科学家 新罕布什尔州农业实验站 (NHAES), whose Station research has focused on cover crop management in the northeast U.S. “通过研究作物行向和覆盖种植之间的相互作用, we hope to uncover new insights that will help farmers increase productivity while preserving essential natural resources.”

这项为期四年的研究将在 主要研究的金曼研究农场, 将测量作物产量, 土壤水分, 杂草抑制和其他农艺和土壤健康变量, 利用无线传感器持续监测光照和土壤状况.

根据朗斯伯里的说法, “持续监测关键变量, 比如光合有效辐射, 土壤水分 和 temperature will provide insight into the extent to which altering row orientation can facilitate unique cover cropping practices, 比如播种到一株直立的作物中, 和 how much these practices affect the climate-readiness of the cropping system.”

这项研究补充了Smith和Lounsbury的NHAES项目, which investigate the potential of interseeding cover crops into st和ing row crops 和 enhancing ecosystem services. The findings from the AFRI-supported study will provide valuable insights into optimizing cover cropping strategies, which will inform 和 enhance the NHAES project’s efforts to promote diversified production systems 和 improve environmental quality within New Hampshire's agriculture industry. 通过整合多种可持续发展, 农业生态的实践, this portfolio of scientific works is intended to provide farmers with tools to reduce dependence on chemical inputs, 节约用水，增强对极端气候的抵御能力.

“以实际行动支持地区农民, 基于研究的解决方案是这项工作的核心,史密斯总结道. “We are committed to helping farmers adopt sustainable practices that will not only improve their yields but also contribute to the overall health of our agricultural ecosystems.”
