Form "Chart Historic Areas and Demands"
If you press the button with the chart symbol on form "Historic Areas and Demands"
a new form will open after a short calculation time. That form gives you an overview about the monthly irrigated areas and irrigation demands resulting from the historic cropping pattern.
The demands shown are calculated monthly irrigation demand values in Million m³ (MCM) at farm gate. They take account of application efficiency and leaching requirements, but not of the distribution efficiency.
The tab-controls on the top of the form permit you to switch between the different hydrological conditions.
The table (which can be copied and pasted to another application like Excel) lists the demands by Main Crop Group. The chart below visualises demands AND areas for all crops together.
The example below contains apparently a high portion of tree crops, that is why areas stay high in the cold season.
