HUMAGRA® NPK 10-0-3 + HA Brochure

DESCRIPTION

HUMAGRA® NPK 10-0-3 + HA Liquid is an organomineral fertilizer which contains humic acids, nitrogen, and potassium. Beside providing these macronutrients to supplement plant nutrition, the product acts as a soil conditioner and plant growth stimulant. It is a permanent humic substance, which is relatively slowly decomposed by microorganisms of the soil. HUMAGRA® NPK 10-0-3 + HA Liquid can be used alone or mixed with most fertilizers.

ORIGIN

HUMAGRA® NPK 10-0-3 + HA Liquid is obtained through alkaline extraction from German Leonardite (highly oxidized lignite), with addition of soluble nitrogen sources. Leonardite arises from the chemical and biological humification of plants and other organic matter, by biological activity and geological processes. This formulation provides a very high content of humic and fulvic acids and a high quantity of nitrogen and potassium.   

BENEFITS

HUMAGRA® NPK 10-0-3 + HA Liquid provides positive fertilizing and soil-conditioning effects, specially in sandy and heavy soils. The product can be applied to all agricultural and horticultural crops, either directly to the soil or as a foliar spray.

  • Increases crop yield and quality
  • Supports the plant with different forms of nitrogen
  • Improves the soil structure and the water retention capacity
  • Increases and stimulates beneficial soil microorganisms
  • Enhances the soil cation exchange capacity (CEC)
  • Increases the effectiveness of fertilizers and reduces nutrient losses
  • Promotes root development
  • Increases nutrient uptake
  • Acts as a natural chelator for microelements in alkaline soils and increases their availability to plants
  • Decreases stress by drought and/or application of plant Treatments
  • Increases the germination of seeds
  • Reduces the residues of herbicides and toxic substances in the soils
  • Prevents nitrate leaching

“All Humintech humic substances based products are analysed according to the HPTA test method (ISO 19822:2018) to determine the content of humic and hydrophobic fulvic acids. Most suppliers are using the more simple “colorimetric” analysis method to determine the humic and fulvic acid contents, but experience shows that, due to its inaccuracy, this method indicates higher contents and is not suited to identify non humic substances such as lignosulphonates. In order to maintain the highest quality standard, Humintech has therefore decided to use the currently best analytical standard for the determination of humic and fulvic acids within the scope of quality control.”
