Soil lysimeter measurements under diverse cropping systems [2017]

This data has been collected for a project funded by the NSERC Strategic Grant Program, the Ontario Soil Crop Improvement Association, Grain Farmers of Ontario (GFO), and the Ontario Ministry of Food Agriculture and Rural Affairs (OMAFRA) to evaluate the impact of diverse cropping systems on soil health, water quality, and greenhouse gas emissions. The lysimeter infrastructure was funded by the Canadian Foundation for Innovation and the the Ontario Ministry of Research Innovation and Science. Measurements were taken from 18 lysimeters containing Elora loam (9) and Cambridge sand (9) soil columns. For each lysimeter, data is available for the weight of the soil column and drainage tank, as well as the soil matric potential, electrical conductivity, temperature, and volumetric water content at depths of 5, 10, 30, 60 and 90 cm.本数据集为一项由加拿大自然科学与工程研究理事会（Natural Sciences and Engineering Research Council of Canada, NSERC）战略拨款计划、安大略省土壤作物改良协会、安大略省谷物种植者协会（Grain Farmers of Ontario, GFO）以及安大略省食品、农业与农村事务厅（Ontario Ministry of Food Agriculture and Rural Affairs, OMAFRA）资助的项目所采集，旨在评估多样化种植系统对土壤健康、水质及温室气体排放的影响。本研究所用的测渗仪（lysimeter）基础设施由加拿大创新基金会（Canadian Foundation for Innovation）与安大略省研究、创新与科学部资助。研究共对18台测渗仪开展测量，这些测渗仪搭载的土柱分为两类，其中9台为埃尔洛壤土（Elora loam）土柱，9台为剑桥砂土（Cambridge sand）土柱。针对每台测渗仪，可获取的数据涵盖土柱与排水罐的重量，以及5、10、30、60和90厘米深度处的土壤基质势、电导率、温度与体积含水量。
