Biologically Priming Soil Opportunities to Build Resilience and Productivity in cropping systems

Modern cropping systems have generally overlooked the sophisticated biological relationships that plants have evolved to survive. In many cases, our modern methods disrupt these beneficial pairings. We are then bound to volatile synthetic inputs, and find we are operating in a degraded soil system. This has led to a merry-go-round of costly interventions for farmers and environmental impacts. Can we farm with the benefits of both worlds? 

Healthy soils are the foundation of farming. But increasingly, we’re facing challenging seasons, input prices and whims of the markets. Biologically priming soil is the act of encouraging or manipulating the biological conditions around a seed or plant to kickstart natural processes that offer a path to resilience and production. 

Biological priming is the intentional intervention at critical growth stages, specifically at germination, to kickstart the symbiotic relationship between plants and microbes. It is the "colostrum" for the seed. Just as a livestock producer would never deprive a newborn animal of that essential package of nutrition, immune signals and microbiome, we must provide our crops with that same foundational microbial start. 

We now know we can intervene in the early stage of a plant’s life with biological primers (biological application) to optimise its microbiome. This leads to measurable improvements in crop resilience, production outcomes, and, crucially, the nutritional density of the food we produce. 

Priming doesn’t work on its own. We need a suitable soil environment in the short term and a commitment to soil health practices in the long term to see the full benefits.

Key Findings

• Brazil: The Bio-Factory model proves that large-scale operations can significantly increase margins by brewing their own targeted microbes. This allows growers to move away from generic inputs toward site-specific biological priming, using locally adapted organisms to drive nutrient cycling and plant resilience.
• USA: A focus on endophyte integrity reveals that seed quality is a biological legacy, not just a genetic one. Sourcing seed from biologically active environments ensures the next generation inherits a robust microbiome: an internal 'starter pack' of microbes pre-programmed for resilience.
• United Kingdom: High-output systems prove that liquid primers, such as compost extracts, can be integrated into intensive horticulture. These extracts act as a biological 'trigger,' delivering a diverse array of microbes through industrial machinery without losing efficiency or compromising the existing soil biology.    

The Economics & Health

• Economics: Priming allows for the unlocking of legacy soil phosphorus and atmospheric nitrogen by activating or introducing functional groups of microbes, decoupling yield from the price of fertiliser.
• Human Health: Linking microbially active soil to the production of nutrient-dense food highlights the opportunity to address the significant decline in food minerals since 1950.

Top Recommendations 

• For Farmers: Adopt an ’Enhanced Colostrum‘ policy with targeted primers like seed  treatments and in-furrow applications to ensure a robust microbiome from day one.
• For industry: Scale the opportunity. Farmers, industry and business co-operate to build and brew Brazil-scale biotech focusing on locally adapted microbes. This ensures biological priming is grounded in regional conditions, not off-the-shelf solutions. 
• For Australia: Establish a national "Soil Health Framework" to provide a common language for soil health and management.
