Agriculture faces a difficult balancing act. Farmers need to produce more food while reducing their environmental footprint. Nitrogen plays a central role in that challenge.
Nitrogen is essential for plant growth, yet synthetic nitrogen fertilizers are among the most resource-intensive inputs in modern agriculture. Their production consumes large amounts of energy and their use contributes significantly to greenhouse gas emissions.
Legume crops offer a remarkable natural alternative.
Plants such as soybean form a symbiotic partnership with soil bacteria. These bacteria can capture nitrogen directly from the air and convert it into a form the plant can use. When this biological nitrogen fixation works efficiently, it allows farmers to reduce their reliance on synthetic fertilizers while maintaining productivity.
In theory, this natural system is extremely powerful. In practice, it is also fragile.
The interaction between plant and bacteria depends on a complex chain of biological signals and environmental conditions. Soil fertility, weather conditions, plant genetics and stress factors can all influence whether the symbiosis develops properly. As a result, the performance of biological nitrogen fixation in the field is often unpredictable.
This is precisely where the NODIFY project comes in.
NODIFY is a research collaboration between Stamagro and the VIB-UGent Center for Plant Systems Biology. The project combines Stamagro’s expertise in protein hydrolysis and circular protein processing with the research capabilities of the group of Prof. Sofie Goormachtig, internationally recognised for its work on beneficial plant–microbe interactions and legume nodulation.
Together, the partners investigate whether specific bioactive peptides derived from circular protein streams can strengthen the interaction between legumes and nitrogen fixing bacteria.
Rather than supplying nutrients directly, these molecules may act as biological signals that help the plant and bacteria establish their symbiotic relationship more efficiently. The research focuses on understanding how these peptides influence the early stages of nodulation and under which conditions this effect can occur reliably in the field.
The idea builds on a broader scientific insight. Protein side streams often contain a wealth of biologically active compounds that remain largely unexplored. With the right processing technologies and biological understanding, these compounds can potentially be transformed into highly targeted agricultural tools.
Early field observations indicate that even extremely small quantities can already have measurable effects.
In soybean trials, application rates of roughly 50 mL per hectare have been associated with yield gains in the range of 300 to 600 kilograms per hectare.
These early results illustrate what becomes possible when protein processing moves beyond commodity ingredients and begins unlocking biologically active peptide fractions.
Beyond the scientific curiosity, the potential impact is significant. Strengthening biological nitrogen fixation could help farmers reduce their reliance on synthetic nitrogen fertilizers, lowering both production costs and the environmental footprint of crop production. At the same time, it creates a new pathway to transform underutilised protein side streams into high-value circular solutions for agriculture.
This is particularly relevant in regions where farmers are under increasing economic pressure. In major agricultural markets such as the United States, fertilizer costs and operational constraints are pushing growers to look for ways to reduce nitrogen inputs without compromising productivity. Solutions that help crops rely more on biological nitrogen fixation could therefore play an important role in keeping farming both profitable and sustainable.

This is exactly the type of challenge the NODIFY project aims to address.
For Stamagro, the project reflects a broader shift in how protein hydrolysates are developed.
Rather than producing generic ingredients, the ambition is to carve specific peptide fractions with a clearly defined biological function in the plant.
This approach could pave the way for a new generation of precision biostimulants derived from circular protein streams.
