Improved support for permanent crops (asparagus, rhubarb) and over winter crops (cauliflower, spinach).

Improved estimation of the soil mineral nitrogen (Nmin), if crops are terminated and incorporated before harvest (for example after hail damage or crop protection problems).
The software now uses the latest Java 9, so 32-bit systems are no longer supported.

By default, fertilizer recommendations and nutrient balances are calculated according to the requirements of the German Fertilizer Ordinance 2017 . Users for whom the Fertilizer Ordinance 2017 does not apply (small businesses, allotments, companies outside Germany) can also continue to use the calculation methods used so far.
When fertilizer measures are entered, the amount of fertilizer is now used to calculate and display the amount of nutrients applied. For organic fertilizers, it is shown how much N is available to plants in the year of fertilization.

The program now estimates the time course of nitrogen release from organic fertilizers and considers this amount of N in fertilizer recommendations.
The database of organic commercial and industrial fertilizers has been considerably expanded and new parameters have been recorded. The N release is estimated depending on the type of fertilizer, the N content and the C/N ratio of the fertilizers.
The soil temperature is also taken into account. Each farm is assigned long-term averages of soil temperatures. The user can use these long-term averages or enter actual soil temperatures himself.

- Updates to the database will be posted on the IGZ server and automatically loaded by the program.
- Small UI improvements.

- Big update from version 3 – the program has been completely reworked, the database has been updated.
