We have divided the different elements of your water balance into colored zones for easier reading of the risks on your crops.
The graph shows the Total Available Water (TAW) of your soil (indicated on the y-axis).
It is divided into two parts: a green and a yellow part. This is the boundary (brown line) between the Readily Available Water (green) and the water that is more difficult for the roots to access (yellow).
🟠🔵 Orange/Blue Line: Water Available in the Soil (mm)
This line represents the total amount of water available in the soil, taking into account effective rainfall and any irrigation you have done.
If the water available in the soil falls within the Readily Available Water zone, the line will be blue. If it falls below this zone, the line will turn brown.
Available Water (day n) = Available Water (day n-1) + Rainfall + Irr - ETc
🟩 Green zone: Readily Available Water (mm)
This zone is the reserve that is easily accessible to the plant. It corresponds to the volume of water that the soil is capable of holding and that can be returned to the crop.
It is expressed in mm and is established based on your crop.
🟨 Yellow zone: Reserve
In this zone, the plant enters a potential water stress situation.
Without water, it decreases its evapotranspiration activity to conserve its energy and survive.
Without a water supply, it will reach the wilting point, where the capillary retention force exceeds the maximum root suction force.
💠 Blue bar: Rainfall
The blue bars represent the rainfall recorded by your Raincrop. However, only a part of this rainfall is actually taken into account in the calculation, these are the effective rainfalls.
🟢 Green bar: your irrigation
The green bars represent the irrigation you added to the app.
You can either enter a quantity of water by irrigation or if you are using a drip system, you can simply add the amount of water you added to your soil by day.
