7 Benefits of Liquid Biostimulants for Cereal Crops
Quick Summary
Liquid biostimulants are substances applied to cereal crops in small amounts to support plant growth, rather than to supply nutrients as fertiliser does. Reviewed evidence suggests they can support antioxidant defence, photosynthetic efficiency and the uptake of water and nutrients.
- Liquid biostimulants support how a plant grows rather than supplying nutrients the way fertiliser does.
- Reviewed evidence suggests effects on antioxidant defence, photosynthetic efficiency and water and nutrient uptake.
- Velcourt trial work found AminoA FLO added to reduced fungicide rates maintained winter wheat yields.
- The same trial reported improved green leaf area in winter wheat.
- Set up untreated areas in the same field and record identical measurements to judge results on your own land.

What Liquid Biostimulants Are and How Amino Acids Fit In
Last Updated: 29 October 2026
Liquid biostimulants are substances applied to crops in small amounts to support how a plant grows, rather than to supply nutrients in the way fertiliser does. At AminoA, we manufacture L-α amino acid biostimulants, and the category is easier to judge once you separate what a biostimulant does from what a fertiliser does.
Amino acids are the building blocks of plant proteins and enzymes. The published review evidence suggests that biostimulants can support plant processes including antioxidant defence, photosynthetic efficiency and the uptake of water and nutrients, though the search results we reviewed do not quantify these effects for every product.
What matters for a grower is the form of the product. Our amino acids are produced through enzymatic hydrolysis and are 100% L-form. The product also contains nitrogen, potassium, iron and magnesium.
Root and Canopy Development in Cereal Crops
Root and canopy development are relevant considerations in cereal crops.
Check root architecture in plants from treated and untreated areas, not just the top growth.
Our products help improve root development.
Helping Cereals Cope With Drought Stress
Drought is where biostimulants attract the most interest, and where the claims need the most care.
Our amino acids are formulated to help plants resist cold, heat, drought and agrochemical phytotoxicity.

Nutrient Uptake and Compatibility With Fertiliser Programmes
Our products have a high content of nitrogen, potassium, iron and magnesium.
Before you tank-mix, check compatibility on a small scale. Our soil pH and rhizosphere health guide explains how soil conditions affect root health before you set up test plots.
Timing Applications Across the Cereal Growing Season
Record the timing and the conditions, so you can compare seasons properly.
What Field Evidence Says About Cereal Yield
Trial work conducted by Velcourt found that adding AminoA FLO to reduced fungicide rates maintained yields and improved green leaf area in winter wheat.
Judge the evidence on your own trials.
The Velcourt trial results are summarised below.
| Item | Value | Note |
|---|---|---|
| Trial operator | Velcourt | Winter wheat trial |
| Product tested | AminoA FLO | Added to reduced fungicide rates |
| Reported outcome | Yields maintained | Compared with reduced fungicide alone |
| Canopy effect | Improved green leaf area | Reported in the same trial |
Judging Whether Your Liquid Biostimulant Is Working
Set up strips or blocks in the same field, keep the untreated areas, and record the same measurements in each. Our practical guide to measuring nutrient uptake in field crops sets out the methods to use.

Frequently Asked Questions
What are liquid biostimulants?
Liquid biostimulants are products applied to crops to support natural plant processes such as root growth, nutrient uptake and stress response, rather than to supply nutrients directly. AminoA's products are based on 100% L-α amino acids produced by enzymatic hydrolysis. Because the evidence for individual products varies, growers should check trial results for the specific product and crop.
Do biostimulants increase cereal crop yields?
Growers should judge yield response on their own fields rather than rely on general averages.
When should liquid biostimulants be applied to cereals?
Pricing depends on quantity, dates and delivery, so check current prices directly with AminoA.
Can liquid biostimulants be used alongside fertilisers?
They are often used alongside fertiliser programmes, but tank-mix compatibility should be checked before mixing. Test small quantities and confirm with the product label and your agronomist, particularly where you also apply fungicides or insecticides, to avoid phytotoxicity.
