SOP solub – Potassium Sulfate

SOP SOLUB – HIGH K2O CONTENT

SOP solub is the potassium sulfate of EuroChem. It is a solid water-soluble fertilizer with less than 0.5 % insoluble matter. It is the most concentrated chloride free source of potassium in the market.
Our SOP solub is in form of small crystalline free flowing powder, which dissolves very quickly in water.

Potassium sulfate is ideal for use in greenhouses, fertigation systems and for foliar fertilizer application of cereal, vegetable, fruit, flower and ornamental crops. SOP solub is involved in carbohydrates metabolism. Application of potassium nitrate improves plant resistance to stress conditions.

SOP solub – Properties
  • SOP solub is a water-soluble fertilizer, produced in a sustainable and natural process, approved according to regulation (EC) 834/2007 and (EC) 889/2008 for use in organic farming systems.
  • K2O content of minimum 52 %.
  • Improves the quality and shelf life of fruits and vegetables, contributes to better accumulation of starch in potatoes, sugar in sugar beet and other root crops, helps strengthen the stems, which prevents crops from drowning.
  • Ensures optimum uptake of potassium and sulphur.
  • It is also an excellent source of soluble sulphur, containing 18 % of this important secondary macronutrient.
  • Composed exclusively of nutrients and does not contain any element harmful to the crops.
  • Our potassium sulfate has a very low salinity index, which limits the risk of having soil salinity problems.
  • Available in 25 kg bags and big bags.

SOP solub – Application

Can be applied in any crop but especially in crops which
are sensitive to chloride, such as tobacco and some fruits
and vegetables. Our SOP solub contain less than 1 %
chloride, no sodium or heavy metals.

Suitable for hydroponics, fertigation, foliar feeding
and any other process where virtually 100 % nutrient
fertilizers are required.

Except to products containing calcium, SOP solub can
be mixed with nearly all other water-soluble fertilizers.

It is widely used in fertigation programs in the late stages
when potassium is required in high amounts, without too
much nitrogen.
