Biostimulants are becoming a favoured tool in the grower’s armoury. This is because the organic materials contain favourable benefits to alleviate crop distress and promote plant development. Our Fielder range of biostimulants have been designed in line with the latest scientific research. Consequently, they deliver improved nutrient uptake, enhanced vitality and better quality in the crop. Furthermore, they can be used on organic crops.
What are the benefits of biostimulants?
- Enhanced nutrient uptake
- Boosts tolerance to abiotic stresses – such as drought resistance or low and high temperatures
- Can be used on organic crops
- Boosts vegetative growth and vitality
- Has overall effect of improving quality and final yields
- Offer a credible and sustainable alternative to banned and restricted actives

Amino Acid Complex Biostimulant


Our premier biostimulant is comprised of Amino Acid complexes and natural sugars. These are known to alleviate nutritional or physiological stresses, whilst aiding the uptake of nutrients. We recommend Amino Acid Complex for effective use on arable and horticultural crops. A further positive is that our Amino Acid biostimulant can also be used on organic crops.
Amino Acid contains 19 essential amino acids, which are vital for the likes of photosynthesis, nitrogen uptake, protein and carbohydrate synthesis. These are sourced only from vegetable protein, so that they can be more easily absorbed by the plant.
Sold as a liquid in 1L, 5L and 10L containers.
Humic30 Acid Biostimulant

Our Humic30 is an extremely effective biostimulant for use on arable, horticultural, and amenity plants.
Fielder Humic30 provides a concentrated dose of essential nutrients, vitamins and trace elements including N, P, K, Ca, Cu, Zn, Fe, Mn, Co, S, B, I. If applied in conjunction with fungicides and nutrient products they act as a chelating agent improving uptake and utilisation.
With Humic30, we see:
- strong root growth by accelerating cell division
- stress alleviation
- improved nutrient availability and uptake
- chlorophyll development is promoted aiding photosynthesis
- natural resistance to pests and diseases is enhanced
Sold as a liquid in 1L containers.
Seaking Biostimulant – concentrated seaweed extract

Our Seaking biostimulant is a combination of complex seaweed extracts and natural nutrients.
Seaweed is known to alleviate crop stresses, including drought tolerance and nutrient deficiency. Therefore, Seaking is ideal to use on agricultural and horticultural crops. It also promotes strong root and plant growth. And it can be used on organic crops.
Sold as a liquid in 10L containers.
