Applying precision irrigation solutions to optimize the management of water resources can prove to be a key factor in countering the sudden climate changes we are witnessing; from the rise in temperatures in Southern Italy, resulting in prolonged periods of drought, to the increase in rainfall in the Northern regions, which delays corn sowing and favors the development of tomato diseases.

It is therefore essential to understand which measures to adopt for careful use of water in the field.

With Agricolus it’s possible to consult the weather forecast, updated every hour for each field, and constantly monitor the situation. Furthermore, it is possible to connect the weather stations present in the plots and view the transmitted data.

The information obtained from forecasts and weather sheds allows the system to feed the forecast model for irrigation, from which it’s possible to simulate the water balance of the crops, calculating some specific parameters.

The Agricolus irrigation model

Among the tools for carrying out precision irrigation, forecasting models represent a valid ally for farmers.

The Agricolus irrigation model elaborates a water balance that takes into account various parameters (such as soil texture, rainfall and present crop) to provide advice on when and how much to irrigate.

It is fed by rainfall data and recorded irrigation operations, and provides constant updates on the values ​​of the water deficit curve, which corresponds to the amount of water missing compared to the field water capacity.

There are two other reference curves: the optimal threshold (deficit level below which the crop begins to suffer stress) and the critical threshold, also known as the wilting point, which represents the ultimate limit to avoid serious water damage.

The model alerts the farmer when the deficit falls below the optimal threshold, indicating the quantity of water to be supplied. Furthermore, it’s possible to consult the table which shows the evapotranspiration and water deficit data on a daily basis to plan irrigation operations according to your own needs.

The use of this precision irrigation tool allows to prevent stress and reduce water consumption, reaching approximately 50% savings.
