The water saving, obtainable through DSS for theprecision irrigation, is a important goal for agricultural companies, for both environmental and economic reasons.

The adoption of conscious irrigation practices It is an effective tool available to farmers to pursue this objective, both in periods of low water availability and when rainfall may lead one to believe this problem is less pressing.
On the contrary, It is precisely the average rainy agricultural seasons that make the adoption of tools for calculating water requirements more useful and effective of crops such as TETHYS Aqua.
In these cases rely on irrigation on the calendar based mainly on past experience and on "what has always been done" could lead to higher water use to what would be necessary for the vigorous and healthy growth of crops.

Calculating a daily water balance is the main tool to avoid overwatering

Calculating the water needs of crops allows you to provide them with a water supply only when and how much is necessary, as it allows us to evaluate whether the water retained in the soil is actually available to the crops through the roots and for how long it will be available.
Irrigating according to the water needs of the crops, but avoiding saturating the soil's capacity to store water, the so-called field capacity, it is therefore possible avoid the phenomenon of runoff. Rainwater runoff on the surface of the ground occurs when it cannot penetrate deep into the ground because the infiltration capacity of the ground itself has been exceeded.
