原始语种摘要: Abstract(#br)Monitoring soil salinity (EC e ) is important for planning and implementing agronomic and irrigation practices. Salinity can be measured through soil sampling directed by geospatial measurements of apparent soil electrical conductivity (EC a ). Using data from a long-term (1999–2012) monitoring study at a 32.4-ha saline field located in California, USA, two established field-scale approaches to map and monitor soil salinity using EC a are reviewed: one that relies on a single EC a survey to identify locations that can be repeatedly sampled to infer the frequency distribution of EC e ; and another based on repeated EC a surveys that are calibrated, each time, to EC e estimation using ground-truth data from soil samples. The reviewed approaches are very accurate and reliable,...
