FULVAGRA® 25 Liquid is an extremely bioactive growth promoting and soil improving agent in liquid form with a high concentration of natural fluvic acids. FULVAGRA® 25 Liquid is 100% water soluble and suitable for all crop and garden cultures for leaf and soil application. It may be used alone or in combination with soluble fertilisers and current plant protection agents.


FULVAGRA® 25 Liquid is obtained from high-humic sources. It is gently concentrated during subsequent processing. No further chemical additives are added. This process is patented and a guarantee for the constant high quality and the unmistakeable clear, golden-yellow colouring.  


Due to the size of the molecules, the fulvic acids in FULVAGRA® 25 Liquid can easily be taken in via the leaves and the roots. In addition, the chelating effect favours the take-up and transport of secondary macro-nutrients and micro-nutrients within the plant. FULVAGRA® 25 Liquid improves not only the utilisation of nutrients from fertilisers, but also the mobilisation and availability of determined nutrients in the soil. 

  • Increases the yield and improves the quality of the plants
  • Stimulates enzymatic activity and increases the plants`own defences against 
    abiotic stress factors
  • Promotes the take-up and transport of micro-nutrients in leaf fertilisers
  • Acts as an anti-oxidant against free radicals and thus prevents cell damage
  • Promotes root growth
  • Increases the germination of see and supports radicle development
  • Increases the microbial activity in the soil since it represents a valuable carbon source 
    for micro-organisms
  • Increases the cation exchange capacity (CEC) of the soil
  • Acts as natural chelator for essential nutrients in the soil and increases their usability for the plants 



Vegetables and decorative plants (greenhouses), cereals, potatoes, legumes, sugar beet, nurseries, gardening and landscaping, lawns, fruit growing
Leaf application: 0.5% solution, 200 - 1000 litres/ha; Ground application: 30-50 litres/ha and year; in 200 – 1000 litres water; total amount may be split into 2-3 individual applications.

Liquid fertilisation (channel irrigation, hydro-culture)
10-20 ml/1000 litres fertiliser solution

Seed treatment
Submersion of seed in the 0.05% solution (5 ml/10 litres water), for approximately 
5 hours, then dry 

Plant substrate (e.g. potting soil, tree substrate)
300 - 500 ml/m3 plant substrate: Dilute Fulvagra to ensure good distribution within the substrate

* This recommendation may be varied according to the soil characteristics and local conditions.
