摘要: The development of site-specific crop management is constrained by the availability sensors for monitoring important soil and related conditions. A mobile time-domain reflectometry (TDR) unit geo-referenced measurements has been developed used detailed mapping water content electrical conductivity within two research fields. Measurements made during early or late season, when moisture levels are close to field capacity, amount plant available texture. Combined closely clay silt fractions a variable field. application season content, presented. maps be automated delineation units. Based on spatial analysis measurements, recommendations with respect sampling strategies. Depending variability given area, between 15 30 ha can mapped sufficient detail 8 h.
