A top quality fertilizer with urea, potassium, magnesium, dextrose and fulvic acid that increase the ability of the plants to absorb nutrition.

Leaf fertilizer based on Fulvic acid for plants that require the supply of potassium, magnesium 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 micronutrients and trace elements.

Use & dosage

Dosage 50 – 75 liters / ha in 300 – 400 liters of water. First application at ground temperature 6-8 C.

pH value
2.5 – 3.5

Surface / Treatment
Suitable for use in all types of nutritional solutions for drip and spray irrigation. Also for leaf fertilization.

Amount / ha
Mix with water 1.5 / 100 liters. Up to 5 liters, depending on the size of the plant.

Water / ha
Leaf fertilizer, amount of water as needed (plant size)

1 – 2 times every 14 days. Applies from when there are one to two charactersheets. After flowering, PROGROW POTMAG DX is advantageously used with PROGROW BOOSTER DX every two weeks for best results. The products have documented good miscibility with most plant protection products.

Product information

Fulvic acids form a natural part of the soil’s organic content. They chelaterate mineral and trace elements so that the plants’ ability to absorb nutrition increases sharply. Increased nutrient availability and nutritional uptake provide both increased growth and post-harvest quality, while reducing the amount of fertilizer.

  • Products containing fulvic acids generally provide:
  • Increased germination rate when sown
  • Improved root development and increased nutrient uptake
  • Stronger and stronger cell walls, stronger plants
  • Improved growth in low light


Nitrogen (N): 3.5%
Dextrose: 2.5%
Potassium (K): 8.4%
Fulvic acid (of which concentrate 9-12%): 25%
Magnesium (Mg): 2.5%

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
