ATSnal – WATER AT RIGHT QUANTITY AND AT RIGHT TIME –
Maintainer and controller of the wetland
ATSnail is an electro-magnetic device that controls and maintains the humid area above it. The device is able to keep the humid area near its maximum field capacity with optimum values between 0 and – 0.3 bar of free water (when it is placed in the ground at a depth between -20 and -40cm). Therefore, ATSnail achieves a precise irrigation without wasting water by deep percolation. It also accomplishes an optimal control of the humid area. Hence, that protects the crop from water stresses caused by excessive or insufficient irrigation. ATSnail is particularly effective in piloting irrigation in well-worked and loose soils with sub-irrigation systems. The device can replace irrigation control units and programmers, (in sub-irrigation, drip irrigation and dripline irrigation) or it can integrate them by taking the place of the rain sensor. In fact, it has a similar ON-OFF approach.
A switch is automatically included with ATSnail in the programmer control unit. If the soil is wet within the range of 0 to – 0.3 bar, it will not start the irrigation. Instead, it will proceed with irrigation if beyond the threshold of – 0, 30, – 0.35 bar to restore the original optimum values. In this case, it will establish the delivery times as the quantity of water delivered over time will be equal to and near to the maximum field capacity of the soil.
ATSnail is an irrigation device unique in its kind because it solves the primary problem of an agricultural crop:
HOW MUCH AND WHEN TO IRRIGATE
How much water to give considering the nature and texture of the soil layer in which the crop grows. When to water it knowing the evapotranspiration of the system: soil – plant – atmosphere.
