BLACKPOWER® Liquid Safety Data Sheet

BLACKPOWER® Liquid Front label

BLACKPOWER® Liquid is a liquid soil conditioner based on high quality hypermicronized German Leonardite that contains a high proportion of humic substances. Produced via a high technology micronizing process, the humic particles (< 5 μm) are held in aqueous suspension. As a result, the humic acids, fulvic acids and humins remain as stable molecules, which endure in the soil for a longer period, raising organic matter levels over time and improve the growing conditions for plants.

BLACKPOWER® Liquid improves the structure, the buffer capacity and nutrient exchange capacity of soils. It has a low precipitation reactivity due to low pH – value of 4 allowing compatibility with most pesticides and fertilizers. (Pre–mixing test advised) or lowering alkaline tank mixtures.

BLACKPOWER® Liquid provides sustainable root growth stimulation in soils and improvement of the soil structure. It can be applied in fertigation
and hydroponic systems or sprayed using conventional foliar or sprinkler techniques.


  • Supports the formation of clay–humus complexes and soil aggregation and reduces soil erosion
  • Increases the quantity and the quality of yields through the full utilization of potential nutrients in the soil
  • It has a very high technical and chemical compatibility with liquid fertilizers and plant protective agents (pre–mixing test advised)
  • Increases the biological activity and cation exchange capacity (CEC) in soils
  • Increases biomass production and stimulates CO2 sequestration in soils


  • Agriculture
  • Vegetable Production
  • Fruit Production
  • Substrate Cultivation
  • Hydroponics
  • Turf grass and Landscaping
  • Seed Treatment


3 – 5 L/ha or didived into several applications (1 – 2 L/ha/ha) during vegetation period

50 – 75 ml/100 L water every 2 – 3 weeks over the vegetation period

0.3 – 0.5 L/m3

0.5 % or 500 mL/100 kg seed dressing according to thousand grain weight (T.G.W.)

30 – 50 ml/1000 L nutrient solution during the cultivation cycle

* Standard recommendations that can vary according to soil properties, cultivated crop and local application conditions.


Please remind to shake well the bottle or container prepared mix well before use.


Before use in combination with other agents, first preparation of a sample mix in a small scale is recommended to avoid any risk of flocculation.


Make sure sufficient amount of solution is added to half water filled tank while agitator is running. Add additional substances or crop protection agents before filling the tank fully with water.

according to ISO 19822 | HPTA | AAPFCO | IHSS Analysis method
“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.”
