Biostimulator - SAPROEXTRACT

Instructions for use

To meet our customers needs and organic farms demands, Biodinamika invested a new product line and began producing fully watter soluble and organic bio stimulator in 2020 in fully separated and independent production facilities for the processing and extraction of plant-based organic sapropel. Thanks to this technology, the production of liquid concentrated fertilizer Sapro Extract for fertilizing plants, improving nutrition through leaves and roots has begun.

A unique combination of pure and bioavailable to the plant organic substances and
compounds such as micro and macro nutrients, humic and fulvic acids, amino acids, proteines, fitohormones-citokinins, auxins,
carbohydrates and vitamins B, C from natural, untouched by civilization, nature, which improves
the yield properties of soils and activates plant growth processes. 

To be used for

  • Treatment of seeds and planting material roots; 
  • Fertilizing plants through leaves during vegetation; 
  • Spraying into the soil before sowing; 
  • Plant root fertilization during vegetation; 
  • Promotion of mineralization processes of stubble and straw residues; 
  • Increasing fertility and improving the quality of grown products; 
  • For enrichment and preparation of various substrates, compost or soil mixtures.

Application and rates: 

  • For plant fertilization through leaves, use during intensive growth, 2-3 time during the growing season. Rate: 3.0 l/ha 
  • For fertilizing plants by watering, use during the growing season every 7-10 days. Rate: 1.0l/ 300-400l H2O 
  • For seed coating: 2.0l/ 1 ton of grain. 
  • For plant root treatment, make a solution of 1:100 with H2O 
  • For soil enrichment by spraying, depending on soil properties, rate: 5.0-10.0l/ha


Note for information Sapropel extraction slowly releases organic matter to plants, therefore mineralisation is slow. It is very beneficial for long-term soil improvement, as the positive effect lasts for 5 years. When sapropel is used together with manure the effect is even better, because sapropel improves not only soil fertility but also removes heavy metals from it.

Benefits to the plant: 

  • Stimulates the development of the plant's root system and accelerates further growth processes; 
  • Improves seed germination and seedling survival; 
  • Activates plant immunity and enhances photosynthesis and respiratory processes; 
  • Has anti-stress effect, increases plant resistance to adverse climatic conditions, toxins 
  • and pollution; Ÿ Improves the quality of harvest, increases the amount of vitamins and useful trace elements in fruits and vegetables; 
  • Suitable for use throughout the plant vegetation cycle; 
  • Gives the plant antidote properties with anti-stress effects during the use of pesticides;


Benefits to soil: 

  • Increases the biological activity of the soil, has a regulating effect on the natural rhizosphere microflora, promotes the multiplication of beneficial microorganisms, including nitrogen-fixing microorganisms; 
  • Improves soil moisture retention properties, heavy clay soils become looser; 
  • Helps maintain a fertile layer and humus content in problematic soils; 
  • Helps to clean the soil from pathogenic bacteria and microorganisms as well as fungal pathogens; 
  • Enriches depleted soil and makes it „work“, thus resulting in a fertile layer, and allows to increase humus content in the soil; 
  • The substrate to which sapropel is added is better at retaining moisture, this means that such soil needs less watering; 
  • Natural sorbent is capable to bind organic compounds and to protect materials against leaching.
