Comprehensive Agronomy Services for Smarter Farming Decisions

AgSource has been partnering with farmers, agronomists, and consultants for decades to deliver agricultural soil testing services that power better decisions in the field. Our full range of agricultural laboratory services, including soil testing labs, plant tissue analysis, water quality assessments, and manure management, provide you with insights that go far beyond the numbers. 

We offer agricultural soil testing for nutrient levels, soil health testing for structure and microbes, and soil carbon testing to support sustainable practices. Our plant tissue testing helps monitor crop health, manure testing optimizes nutrient use, and water testing ensures clean irrigation. We also provide greenhouse media testing to improve growing conditions in controlled environments.

Each test is part of a bigger picture to help you track performance, protect your soil’s long-term health, and support responsible resource use across your operation.

Get in touch with an agricultural soil testing expert and take the next step toward healthier crops and higher returns.

What are Agronomy Services?

Agronomy services are the lab testing and technical support that help you translate field conditions into a fertility, product, or management recommendation. At AgSource, that spans soil testing and sampling, plant tissue analysis, manure testing, water testing, scouting, and Nutrient Management Plan writing.

Used together, these services tell a more complete story than any single result on its own. A soil test shows what’s available in the ground; a tissue test shows what the plant actually took up; a manure test quantifies the nutrient value going back into the soil; and a water test flags anything in the water that could affect crop response or product performance. Layering these results helps you build recommendations that protect yield without over- or under-applying inputs and, over time, support the soil health that keeps a field productive.

AgSource pairs the lab work with CCA agronomists who can help you work through what the numbers mean for a specific recommendation with service that goes beyond the test result.

Frequently Asked Questions About Agronomy

Soil testing is one component of agronomy services. While soil testing measures nutrient levels, pH, and other soil characteristics, agronomy services take a broader approach by combining laboratory analysis with recommendations that help optimize crop performance, nutrient management, and long-term soil health.

Depending on your operation, this may include plant tissue, water, manure, or greenhouse media testing alongside soil analysis.

Most fields benefit from soil testing every 2 to 4 years, though high-value crops, intensive production systems, or fields with changing management practices may require more frequent testing. Regular testing helps track nutrient trends, improve fertilizer efficiency, and support consistent crop performance over time.

The right test depends on your goals and the challenges you’re facing. Soil testing is often the best starting point for evaluating nutrient availability and soil health, while plant tissue testing can diagnose in-season nutrient deficiencies. Water, manure, and greenhouse media testing provide additional insights for operations where irrigation, nutrient management, or controlled growing environments are important. An agronomy expert can help determine the most appropriate testing strategy.
Yes. Accurate laboratory testing helps identify current nutrient levels, enabling fertilizer applications to be based on actual crop needs rather than estimates. This can improve nutrient use efficiency, reduce unnecessary input costs, and support better environmental stewardship.

Agronomy testing helps producers make informed management decisions that protect soil resources while maintaining productivity. By understanding soil health, nutrient availability, and water quality, farmers can apply inputs more precisely, reduce nutrient losses, and support long-term soil productivity.

Providing details such as crop type, field history, previous fertilizer applications, intended crop, and any production concerns can help ensure testing is tailored to your operation. Accurate sample collection and complete submission information also contribute to more meaningful results and recommendations.

Laboratory results provide objective data that can guide decisions on fertilizer applications, nutrient management, irrigation, crop performance, and soil improvement strategies. When reviewed alongside field history and production goals, they help producers make more informed decisions throughout the growing season.

Interpreting a report is only the first step, deciding what it means for a specific field, crop , or client conversation is where it gets harder. AgSource’s technical support agronomists are available to work through results with you: flagging nutrient interactions that could be masking the real issue, weighing in on whether a follow-up soil test is warranted, or helping you build the confidence behind a fertility recommendation before it goes to your grower.

We know every operation you manage is different, so this isn’t a generic read of the sufficiency ranges, it’s a conversation grounded in your specific results and the history behind them. Reach out to a member of our agronomy team to talk through your latest report and turn it into a recommendation you’re ready to stand behind.
