We will be embarking 2020 as absolute ISO-experts. Adding a new standard to TerraIndex proved to be a hefty challenge. It required us to not only have extensive knowledge of the standard but also the additions for the Dutch regulatory system.
Over the past six months we went over the current state of the NEN and other Dutch regulations regarding soil analysis, in order to find the best way to apply the ISO standard. We have mapped the various differences between these models, discussed, tested, and reviewed the possible solutions with the Expertgroup and other involved parties.
There are four different ways to input the soil texture in the latest version of TerraIndex App:
- Free input
- Input conforming NEN
- Input conforming the international ISO
- Input conforming the international ISO with Dutch additions (NEN-ISO)
At the request of the various parties and the Expergroup the current input model for the soil texture has been adapted to include fully written text. The current input model in the TerraIndex App is otherwise unchanged.
