This usually takes place 2–3 days after rain or irrigation in pervious soils of uniform structure and texture. The physical definition of field capacity (expressed symbolically as θfc) is the bulk water content retained in soil at −33 kPa (or −0.33 bar) of hydraulic head or suction pressure. The term originated from Israelse…
The SMP value at FC was 23 kPa and at the MAD was 105 kPa. The estimated MAD is consistent with the range of 100-120 provided in Table 4 as cotton MAD. Based on the estimated thresholds, irrigations should have been managed to keep the SMP in between 23 and 105 kPa to avoid water loss and stress.
