Abstract

Deep percolation in the 2020 growing season was 4% of the total water applied in the drip field with 25 irrigation events; for the flooded field, there was 12% of the total water applied that became deep percolation with only 9 irrigations. The sensor installed at 210 cm shows that there may be also some capillary rise in the field that may affect the water movement down in the field.
