Entering data for a crop water balance calculation
For a water balance calculation the following data are needed:
- Actual Rainfall for the period of he water balance calculation (up to the current dekad). There are three ways to read these data into AgrometShell.
- Using the Database-Weather-Dekad function.
- When the data come as ASCII files, using the Database-Import-from ASCII file
- When the rainfall comes in the form of images, it can be imported through the Database-Import-from image function.
- Normal Rainfall for 36 dekads in the year. These data can be read into AgrometShell in the same way as actual rainfall.
- Actual ET0 data for the season up to the current dekad. The ET0 data can be calculated from its base data (temperatures, windpeed etc.. ) using the Database-Calculate-Formula function or the Tools-Potential ET-from file function.
