LTAR Upper Mississippi River Basin - Morris - Swan Lake Research Farm Phenocam

The PhenoCam network is collecting color and near infrared images year-round using cameras in fixed positions on agricultural lands including a site located on the Swan Lake Research Farm. The network effort was initiated in 2015 at this long-term, plot-scale research site. The camera at the research farm on focused a plot-scale, replicated research study that was established in 1997 to assess the long-term impacts of various tillage management options on soil organic carbon. Initially the study included eight tillage treatments: no-tillage, moldboard + disk tillage, chisel tillage, and fall and spring residue management, with or without strip-tillage and strip-tillage + sub-soiling. In 2004, the number of treatments were reduced to no-tillage, moldboard tillage, and fall and spring residue management without strip-tillage. All tillage treatments also had an early or late planting date. In 2008, the strip-tillage plots were modified to explore alternative strategies for supporting cellulosic bioenergy feedstock production, including planting of cellulosic feedstock. The modification included adding perennials grasses into an extended 6-year rotation, winter cereal rye cover crops in a corn-soybean rotation, and an alternative Sorghum-Sudan grass hybrid forage system. Detailed soil and crop properties data have been collected from this site. This site is designated to be continued as part of the LTAR "common experiment" comparing agricultural and environmental results from "business as usual" and "aspirational best practices.

PhenoCam网络全年无休地收集着农业用地固定位置上的彩色及近红外影像，其中一处位于斯旺湖研究农场。该网络项目于2015年启动，旨在这一长期、小规模研究区域内。位于研究农场的研究重点在于对1997年建立的、旨在评估各种耕作管理方案对土壤有机碳长期影响的小规模、重复性研究进行聚焦。最初的研究包含八种耕作处理：免耕、刀耕+碎土耕作、锄耕以及带状耕作与不带状耕作的秋季和春季残茬管理。所有耕作处理均设有早植或晚植日期。2004年，处理方案数量减少至免耕、刀耕和秋季及春季不带状耕作的残茬管理。此外，所有耕作处理均设有早植或晚植日期。2008年，带状耕作地块进行了调整，以探索支持纤维素生物能源原料生产的替代策略，包括纤维素原料的种植。调整措施包括将多年生草类植物纳入扩展的6年轮作周期、在玉米-大豆轮作中种植冬季黑麦覆盖作物，以及采用备选的高粱-苏丹草杂交牧草系统。该地点已收集详细的土壤和作物特性数据。该地点被指定为LTAR“共同实验”的一部分，比较“常规做法”和“理想最佳实践”在农业和环境结果上的差异。本数据集中包含的资源：资源标题：地理数据目录记录。文件名：网页，网址：https://geodata.nal.usda.gov/geonetwork/srv/eng/catalog.search#/metadata/da7457b6-633e-4564-8bb0-2b7d5adbe35d
