Patentkali® – Delivering quality
Recommendation
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) | |||
|---|---|---|---|---|
| Potatoes | 600-1,200 | |||
| Cabbage and root vegetables | 800-1,200 | |||
| Fruit plantations | 400-600 | |||
| Grape vine | 300-400 | |||
| Soft fruits | 600-800 | |||
| Leafy vegetables | 600-800 | |||
| Forestry | 300-500 | |||
