FIGURE 5. Distribution of electrical conductivity in the soil, 1.0 Lh -1 FIGURE 6. Distribution of electrical conductivity in the soil, 1.6 Lh -1 CONLUSION The following conclusions may drawn from the results: (1) There were no significant differences between the dimensions of the wet bulb formed from the application of MWS and TSE to the flow rate of 1.0 Lh -1 in a dusk red latosol at 0.30 m of depth, as well as to the flow rate of 1.6 Lh -1 ; (2) The interactions between the different profiles (water content versus electrical conductivity) revealed a gradient distribution of the solute in the soil near the emitter, decreasing progressively towards the wetting front; (3) Increasing the flow rate from 1.0 Lh -1 to 1.6 Lh -1 raised the horizontal radius of the wet bulb suggesting a wider spacing between drippers, such as recommended by the manufacturer of the dripper.

The following conclusions may drawn from the results: (1) There were no significant<br />
differences between the dimensions <strong>of</strong> the wet bulb formed from the application <strong>of</strong> MWS and<br />
TSE to the flow rate <strong>of</strong> 1.0 Lh -1 in a dusk red latosol at 0.30 m <strong>of</strong> depth, as well as to the flow<br />
rate <strong>of</strong> 1.6 Lh -1 ; (2) The interactions between the different pr<strong>of</strong>iles (water content versus<br />
electrical conductivity) revealed a gradient distribution <strong>of</strong> the solute in the soil near the<br />
emitter, decreasing progressively towards the wetting front; (3) Increasing the flow rate from<br />
1.0 Lh -1 to 1.6 Lh -1 raised the horizontal radius <strong>of</strong> the wet bulb suggesting a wider spacing<br />
between drippers, such as recommended by the manufacturer <strong>of</strong> the dripper.<br />
