A top quality fertilizer with urea, a wide range of minerals, dextrose and fulvic acid that increase the ability of the plants to absorb nutrition.

Leaf fertilizer based on Fulvic Acid for plants that require extra supply of urea, minerals and dextrose. The product increases the nutrient absorption of the plants and makes them less sensitive to stress like cold, drought and large amounts of precipitation. ProGrow Potmag is an environmentally adapted plant and industry based on South African coal, with a broad spectrum of macro, micronutrients and trace elements.

Technical data

Calcium ammonium nitrate with salt of fulvic acid. pH: 2.5-3.5. In very high pH soils, the product lowers the pH at the roots, allowing more nutrients to be available. The product is a concentrated product (9-12% fulvic acid).


Nitrogen (N): 15%
Phosphorus (P): 6%
Potassium (K): 8%
Zinc (Zn): 0.5%
Manganese (Mn): 0.5%
Copper (Cu): 0.25%
Dextrose: 2.5%
Fulvic acid (of which concentrate is about 9-12%): 25%

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
