Field Trials with Amino Acid-Based Biostimulants

Biostimulants containing amino acids provide plants with essential amino acids required for growth.

The underlying hypothesis is that if nutrients are supplied directly in amino acid form, the plant does not need to expend energy synthesizing these compounds itself. Instead, this energy may be redirected toward growth and yield formation. If a plant can bypass parts of its endogenous amino acid synthesis, it may allocate more resources to, for example, developing a more extensive root system. This could enhance resilience to abiotic stress factors such as drought and disease and improve the plant’s ability to explore the soil for additional nutrients. In addition, certain amino acid-based biostimulants have the potential to reduce fungicide use.

This document explores a relatively complex field trial conducted evaluating Aminosol in spring barley using a “checkerboard” design at Knudstrupga rd (Søren Ilsø) in 2023.
