Patentkali® – Delivering quality
To determine the required amount of Patentkali® the following factors have to be considered:
- the potassium and magnesium requirement of the crop or the crop rotation.
- the potassium and magnesium supply and dynamics in the soil (site conditions).
- the varying requirements of the different crops, regarding the accompanying nutrients (e.g. magnesium requirement of potatoes, sulphur requirement of brassicas).
- The quantity of nutrients applied through organic fertilisers.
The recommendation shown in the table below can be taken as a guideline for the fertilisation of some important crops with a medium soil K content. Organic manures are not taken into account.
|Crop||Patentkali® (kg ha-1)|
|Cabbage and root vegetables||800-1,200|
