### Moisture Analysis When Evaluating the Different Irrigation Techniques  
In this section the three irrigation techniques are compared and the moisture that the crop will have is analyzed to verify that it does not exceed the moisture limits. In Figures 4-6 the yellow line representing the moisture level at the end of each day is identified, the blue line represents the maximum water content level at field capacity, the orange line is the minimum level that the crop can obtain and, finally, the gray line is the lower limit \(Pw\) and the readily available water (RAW). The abscissa axis (y) represents the water sheet or moisture in the root zone and the coordinate axis (x) represents the development of alfalfa in a 60-day cycle.

Figure 4 shows the moisture with traditional irrigation where the moisture curve, \((H)\), represented in yellow color, exceeds the curve \((L_{Cc})\) indicated in blue color, where it can be seen that the moisture curve is not affected by the moisture curve.

be observed that there is an excess of water in the different stages of the crop during the 60 days, and the excess water is lost by runoff or by deep percolation.  
Figure 5 shows the soil moisture in the technical irrigation technique, carried out by means of an agronomic design, when observing the soil moisture, \((H)\), represented by a yellow curve, it is evident that there is an excess of water resources because it exceeds the blue curve \((L_{\mathcal{C}c})\) throughout the whole period of the crop, but this excess water is lost and is not usable, so there is a waste of water resources.  
The third irrigation technique is the proposed smart irrigation that uses the daily water balance with a maximum irrigation time of 4 h, shown in Figure 6. The soil moisture, \((H)\), is represented by a yellow curve and is maintained within the range of the allowed limits without causing water stress or saturation of the soil due to excess water  
When comparing and analyzing Figures 4-6 of the three irrigation techniques, it should be noted that the smart irrigation proposal maintains the necessary moisture without causing water stress or soil saturation due to excess water, while the traditional and technified irrigation techniques produce water losses, while the smart irrigation technique makes optimal use of the water resources.
