In an ideal world, farmers would plant a seed in the ground, the seed would grow into a healthy plant, and the plant would produce the maximum output possible, be it grain, fruit, or vegetable. Throughout history, the process of domestication and breeding led to improvements in yield through crop genetics (1). As technology in agriculture has advanced through time, other limiting factors have been identified and addressed. Liebig’s Law of the Minimum tells us that the maximum crop yield is determined by the most limiting essential nutrient (2). In the early 1900s, the process for synthesizing nitrogen fertilizer was developed, and commercial production of other macro- and micronutrients followed (3). Today, the genetic potential of modern corn hybrids is over 600 bushels per acre (4), and growers can apply any nutrients that are lacking. With fertility and genetics research being well-established, what other limiting factors can be addressed with emerging technologies?
Developing technologies to address limiting factors has raised the height of staves in the barrel that depicts Liebig’s Law of the Minimum. (Image design inspired by UF/IFAS Communications.) With data from Trace Genomics, agronomists have the tools to address the limiting factors driven by soil biology.
Historically, as limiting factors for crop yield have been identified, technology has been developed to address them. Synthetic fertilizers addressed nutrient deficiencies, and genetic limitations continue to be improved through advanced breeding techniques and biotechnology. Traditionally, the only available pest diagnostic tool has been to collect and submit soil or plant tissue to an analytical laboratory, generally only done after damage has occurred. While onset of a disease depends on environmental conditions, it would be most beneficial to have knowledge of a soil’s pest profile before seeds are planted. This information allows agronomists to make management decisions before disease has a chance to take hold. Trace Genomics offers the most comprehensive pathogen panel on the market, providing agronomists and crop advisors the tools to make informed decisions to tackle pests through seed selection, seed treatment, potential in-season treatments, and crop rotation.
Other diagnostic technologies may only identify a handful of pathogens or pests at a time, grouped into small packages. At Trace Genomics, we use metagenomics to sequence all soil DNA, testing for over 225 pests at once. While metagenomics technology began with a focus on bacteria and fungal pathogens, DNA from insects and nematodes can also be detected. In Fall 2023, Trace is expanding our list of reported pests by more than 50 species—including notable pests such as Soybean Cyst Nematode (SCN) and Western Corn Rootworm (CRW).
At Trace Genomics, our goal is to provide a thorough soil profile, so agronomists can identify their true limiting factor. Our flagship product TraceCOMPLETE™, includes a full suite of chemistry analytics in addition to revolutionary biological analysis: a list of over 225 pests covering more than 70 crop hosts, as well as biological nutrient cycling data. Actionable insights for pest management are provided in our Seed Solution Guide—an easy to understand summary of the pests in your soil presented alongside relevant chemistry data to help growers make the best management decisions. A full, quantitative list of detected pests can also be found in our interactive online platform, TraceVIEW.
Using insights presented in the Seed Solution Guide and on TraceVIEW, agronomists have more information than ever before to use for pathogen management recommendations.
In situations where in-season pesticide application is not feasible due to the proximity of fields to sensitive areas such as schools, nursing homes, hospitals, residential, or inaccessible areas, a good defense is often the best offense. Soil biological analysis through metagenomics provides a means for understanding what pathogens and pests are present before they have an opportunity to cause damage.
The comprehensive, actionable pest profile delivered with TraceCOMPLETE allows agronomists to make preventative management decisions such as seed selection, seed treatment, in-season treatment, and crop rotation.

What is included:
Seed Solution Guide- Seed Selection, Seed Treatment, In-Season Disease Management
The Seed Solution Guide provides a comprehensive analysis of your soil that includes recommendations for seed selection and treatment depending on pathogen abundance and chemistry.
TracePHOS™ - Phosphorus Fertilizers, Phosphorus Liberating Agents, Biologicals
Delivers soil diagnostics so you can make the best phosphorus management decisions to optimize your soil biology performance and phosphorus use efficiency. With TracePHOS, you can identify areas where your crop would benefit from a biofertilizer or a phosphorus-liberating agent, and determine whether you should build soil phosphorus levels or re-allocate your input resources.
TraceN™ - Nitrogen Stabilizers
Delivers soil diagnostics so you can make the best nitrogen management decisions to optimize your soil biology performance and nitrogen use efficiency. With TraceN, you can identify areas where a nitrogen stabilizer or biofertilizer is desirable based on our unique nitrogen biological indicators.
We’ve taken the guesswork out of seed and seed treatment selection with the ultimate agronomic tool. Our new Seed Solution Guide pairs unmatched soil analysis with hi-definition genomic sequencing to provide accurate, actionable information about relevant pathogen levels and key chemistry parameters in your fields.
Make Smarter Decisions
With easy-to-understand, customized data, you can make informed recommendations and decisions about seed selection, seed treatment and disease management based on your field’s specific pathogen levels and chemical characteristics.
Customize Crops
The Seed Solution Guide is the first configurable report from Trace Genomics. You can choose up to 6 crop types from more than 70 options—the default crops are corn and soybeans, but you can go beyond those to include all of the relevant crops for your operation.
Call It What You Like
Providing insights on permanent crops or others where seed selection might not be the main goal? Agronomists can customize the report name based on their growers’ needs.
If you’re a current Trace user, you can edit your report settings (including the name and the crop selections) by logging into your account. Hover over your initials in the bottom left corner of the window, then select “Profile,” then select “Report Configurations.”
