A soil improver of highest quality with potassium phosphate and salts of humic acid. Enables nutrients, strengthens root systems and reduces irrigation needs.

A liquid nutritional solution and soil improver intended for plants and seeds that require increased supply of phosphorus and potassium. Treatment with PROSOIL products increases the availability of macronutrients in the soil between 1.5 to 2.5 times. ProSoil DKP is an environmentally adapted plant and industry based on South African coal, with a wide range of micronutrients and trace elements.


The first application can be done when the soil temperature reaches 5 ° C. NOTE: The liquid should be shaken vigorously before use.

Water / ha
Should be watered into the soil, water quantity as needed and equipment

1-2 times per year as needed and conditions, soil analysis, and crop.

First application before or during planting. Works as soil improvers in all types of soil, from light sandy soils to heavy clay soils.


Dikalium phosphate and salt of humic acid

Phosphorus (P): 9%
Potassium (K): 22%
Salts of humic acid: 15%
Fulvic acid: <5%
pH: 9


Time to power is usually 3-5 weeks depending on the temperature of the earth. Long-lasting effect.


Store in a temperature between 0-40 ° C. Protect from heat and direct sunlight and store in dry conditions. Opened packaging should be recycled well.

Humic acid improves soil and also makes nutrients more accessible to plants. When adding humic acid, the ability of microbes to break down and mineralize organic matter increases greatly.

The humic acid also enhances the earth’s cation exchange effect and reacts with positively charged mineral ions, thus forming organic complexes. It creates a much more porous soil structure with a positive impact on the root environment, while the soil’s ability to absorb water increases sharply.

The molecule of the fulvic acid has the ability to chelate (bind to) minerals and nutrients so that they are more easily absorbed by the cells of the plants. Growth’s ability to absorb nutrition increases sharply while nutritional turnover and photosynthesis become more active, allowing plants to grow at lower temperatures and in weaker sunlight.

The follaric acid also has a biochemical neutralizing / buffering effect on the soil pH.

A porous soil with greater ability to bind water, more easily accessible nutrients and increased nutrient uptake at the plant cells together give a great effect in cultivation.

  • Harvest increases by 15-30%
  • The amount of fertilizer can be reduced by 30-50%
  • Reduced irrigation needs, up to 50%
  • A better utilization of nutrients, which in turn reduces the risk of nutrient leakage in watercourses
