EC FERTILISER
Potassium sulphate with magnesium 30 (+10+42.5)

  • 30% K2O water-soluble potassium oxide
  • 10 % MgO water-soluble magnesium oxide
  • 42.5% SO3 water-soluble sulphur trioxide (= 17% S)
  • is a special potash fertiliser with a high content of magnesium and sulphur. The nutrients are present in the form of sulphate, are water-soluble and therefore immediately available to the plants. In contrast to many other magnesium fertilisers, the magnesium content in Patentkali is 100 % derived from the natural mineral kieserite (MgSO4 × H2O).
  • is effective regardless of the soil pH and can therefore be used at all locations
  • ensures good spreading quality. The uniform particle size spectrum enables precise distribution even at wide spreading widths.
  • is especially suited for plants with a high sulphur requirement (rape, sunflowers, different kinds of cabbage, onions, leeks, etc.) due to its high sulphur content (42.5 % SO3). A good sulphur supply also improves nitrogen utilisation in plants.
  • is certified for organic farming according to the regulations (EU) 2018/848 and (EC) No. 889/2008.

Usage of Patentkali®

  • Patentkali is especially suitable for the fertilisation of starch potatoes, potatoes for processing, vegetables, fruits, vines, sunflowers and other special purpose crops
  • The use for processing potatoes and table potatoes leads to improved quality (low blackspot bruising, good storage properties, good taste) and for starch potatoes to an increase in the economically crucial starch yield.
  • The quality-enhancing effect of Patenkali is preferably used in the cultivation of fruits and vegetables (many vegetable plants are chloride-sensitive) as well as in viniculture.
  • Patenkali is well suitable for the revitalisation of damaged forests with proven K and Mg deficiency.
  • The application of Patentkali significantly improves the green colouring of Christmas tree crops and greenery.
  • In viniculture to ensure a sufficient potassium and magnesium supply.

Harvest quality with Patentkali®

  • The nutrients potassium, magnesium and sulphur have a significant effect on the quality of the harvested crops. They control important enzyme functions and especially aid protein synthesis and production of carbohydrates and vitamin A.
  • The sufficient supply with these nutrients ensures high yields and is at the same time an essential requirement for achieving product qualities fit for the market.
  • Drastically reduced sulphur emissions from the atmosphere have already led to sulphur deficiency symptoms in several crops that can only be prevented by relevant sulphur fertilisation. Patentkali with a guaranteed sulphur content of 17 % in immediately plant-available form prevents this deficiency.
  • Due to the extremely low chloride content of max. 3 % Cl and the low salt index, Patentkali is especially suitable for the nutrient supply of chloride-sensitive crops in agriculture, horticulture and forestry

Time of application

  • Patentkali can be applied to all crops until shortly prior to sowing or planting. Top dressing is also possible without any problem.
  • On light soils, Patentkali should be applied in spring.

Fertilisation recommendations

The following factors have to be considered when calculating
the amount of Patenkali that should be applied:

  • the potassium and magnesium requirement of the crop or the crop rotation
  • the potassium and magnesium supply and dynamic of the soil,
  • the requirements of different crops regarding the macronutrients (for example magnesium requirement for potatoes, sulphur requirement for different kinds cabbage),
  • the amounts of nutrients supplied by organic fertilisation.

The following recommendations serve as general guidelines for
the fertilisation of soils with medium potassium contents, not
taking organic fertilisation into account.
