Determination of Soil Physical Properties and Pre-Sowing Irrigation Depth from Electrical Resistivity, Moisture, and Salinity Measurements

Seeds require adequate soil moisture prior to planting, and pre-sowing irrigation depth (PSID) represents the optimum seed level. This work proposes a new methodology obtain physical properties PSID, that includes application of electromagnetic profiling method (EMP) as fast non-invasive technique. Soil electrical resistivity measurements obtained from an EMP survey are combined with salinity information experimental input for PetroWin program. The program uses Ryjov’s theoretical model determine fines content porosity, then, PSID values determined. At study site, variations in were controlled by moisture, not salinity. rooting crops was limited thickness 0.6 m. A between 8 9 cm determined resulting total water volume required 5313 m3 ensure reaches field capacity. proposed constitutes effective efficient tool determination parameters agricultural soils and, consequently, sustainable use water.
