Reliable Potassium Source for Sensitive Crops
Patentkali Kalimagnesium is a high-quality, low-chloride fertiliser with a high concentration of potassium, magnesium, and sulphur. The fertiliser is approved under EU Organic Regulation 2018/848 and recognised by leading organic certifications such as Bioland, Naturland, Gäa, and Demeter. Thanks to the presence of natural kieserite, it ensures fast and direct nutrient availability, making this fertiliser particularly suitable for chloride-sensitive crops.
Patentkali is especially well-suited for use on lighter soils, where the risk of salt damage is higher. Its low chloride content makes it a safe choice for sensitive plants. The product is widely used in professional cultivation, including starch potatoes, fruit trees, nursery crops, and vegetable crops, but it is also highly effective in home vegetable or ornamental gardens. It proves its value in crops such as potatoes, tomatoes, peppers, grapes, berries, ornamental plants, and flower bulbs. Its balanced composition allows for targeted and efficient application of potassium, magnesium, and sulphur without adversely affecting soil pH or soil life.
Premium Low-Chloride Fertiliser for Organic Cultivation
Patentkali Kalimagnesium supports the plant throughout multiple growth stages. The potassium present promotes sugar storage, drought tolerance, and winter hardiness. Magnesium stimulates root system development and contributes to strong plant structure. Sulphur is essential for the formation of chlorophyll and proteins, and also supports the uptake of other nutrients. This combination makes the fertiliser highly versatile as a base nutrition in organic farming, as well as in ornamental gardens and hobby cultivation.
The granular form ensures even distribution and allows for both manual and mechanical application. With 30% potassium, 10% magnesium oxide, and 44% sulphur trioxide in fully water-soluble form, Patentkali is particularly well-suited for use at the beginning of the growing season. Thanks to the low salt index and minimal chloride content, the risk of crop damage is kept to an absolute minimum. Its effectiveness is reliable on all soil types, regardless of pH, and aligns with a balanced, natural fertilisation strategy.
Sustainable Choice with Guaranteed Safety
Patentkali Kalimagnesium is classified as non-hazardous under Regulation (EC) No. 1272/2008 (CLP) and can be safely applied when used as directed. To protect both people and the environment, applicable safety regulations must be carefully followed. By using the product correctly and in compliance with relevant legislation, including Regulation (EC) No. 1272/2008, it contributes to sustainable and responsible fertilisation in both organic and conventional agriculture and horticulture. Patentkali also offers a safe and effective solution for targeted potassium and magnesium application in home vegetable or ornamental gardens, without burdening soil life or posing a risk of over-fertilisation.
Composition
Patentkali Kalimagnesium is a granular mineral fertiliser of the type PFC 1(C)(I)(a)(i). Its composition consists of fully water-soluble nutrients that ensure rapid and efficient uptake by the plant.
- 30.0% (K₂O) – water-soluble potassium oxide
- 10.0% (MgO) – water-soluble magnesium oxide
- 44.0% (SO₃) – water-soluble sulphur trioxide (= 17.6% S)
This granular fertiliser consists of uniform granules with a particle size of 5.0 mm, ensuring even distribution and precise application, even when spread over larger distances.
Raw Materials
- Potassium sulphate (CAS no. 7778-80-5)

Application and Instructions for Use
Patentkali Kalimagnesium is suitable for all crops and, thanks to its low-chloride composition, particularly well-suited for sensitive cultivations. Use the fertiliser only when there is a demonstrated need for potassium, magnesium, or sulphur. Application as a base fertiliser is preferably done in autumn or, on lighter soils, in early spring.
The fertiliser should be evenly distributed around the plants or across the field and lightly incorporated into the topsoil. Avoid direct contact with leaves or roots. Thorough watering after application promotes nutrient uptake and increases effectiveness.
Recommended Dosage
- Lawn: 25–35 g/m²
- Cabbage, root and bulb crops (e.g. cabbage, carrots, onions, leeks): 80–100 g/m²
- Potatoes: 60–80 g/m²
- Fruit crops (fruit trees, wine grapes, berries, strawberries): 30–60 g/m²
- Vegetables (tomatoes, peppers, lettuce, leafy greens, legumes): 30–70 g/m²
- Asparagus: 40–60 g/m²
- In case of visible potassium deficiency: 80 g/m²
Application Period
The fertiliser is best applied in early spring, from March to April, or in autumn, from September to November. During these periods, the uptake of potassium, magnesium, and sulphur is most efficient. A spring application promotes strong root development and a good start to the growing season, while an autumn application contributes to increased winter hardiness and a healthy end to the cultivation cycle.
Storage
Store in the original, tightly sealed packaging. Protect from direct sunlight and temperature fluctuations. Keep in a dry, well-ventilated place at +2 °C to +30 °C. Keep out of reach of children and pets. Avoid discharge into waterways or sewers.
