Abstract

Soil water distribution due to clay pots irrigation with various negative pressures and drip irrigation investigated in the agricultural lands of the Urmia plain. This research was performed on 4 irrigation lines (4 treatments), 3 pot irrigation lines with pressures of 0,-5 and -15 cm and one drip irrigation line. The soil moisture were measured for 3 pots (3 replications) per irrigation line at locations 15, 30 and 45 (cm) away from the pot center and the six depths of 10, 20, 30, 40, 60 and 100 (cm) with TDR-PR2 in a period of 4-day. In the drip irrigation line, the measurements were performed in the same conditions for three emitters. The soil texture was classified as Clay Silt Loam according to USDA system. Also, the soil wetting pattern of the pots and the emitters were simulated using a two-dimensional HYDRUS model. The statistical analysis showed a significant difference among the soil moisture values in the irrigation lines. The results of the simulation model showed the measured and the simulated moisture pattern were in good agreement with each other. The results of modeling demonstrated that by reducing the negative pressure in the pots, the model simulation gets underestimate. The soil water values in line -15 (cm) and drip irrigation were the lowest and the highest values, respectively. This research can be effective in the design of an optimized clay pot irrigation method with negative pressures in arid and semi-arid areas which are facing a water crisis.
