Know your soil. Grow with confidence.

At AGRIS Co-operative, we believe that healthy soil is the foundation of a productive and sustainable farm. That’s why our soil sampling services are built on agronomic science and tailored to your farm’s unique needs. 

Why Soil Sampling Matters

Soil testing every four years or less is the first step in making informed decisions that are both agronomically sound and environmentally responsible. It supports your 4R Nutrient Stewardship compliance and ensures your nutrient applications are optimized for yield and sustainability.

Our Proven Nutrient Management Approach

We follow a Build, Maintain, or Draw-down model to manage soil fertility:

• Build: If soil test levels are low, we recommend more than crop removal rates to build up fertility.
• Maintain: If soil tests are within target ranges, we apply nutrients equal to what the crop removes.
• Draw-down: If soil fertility is high, we may recommend less than crop removal—or even a zero-rate—to responsibly use what’s already available.

This strategy ensures your soil has the nutrients it needs—no more, no less—reducing environmental impact and maximizing return on investment.

Choose the Right Soil Sampling Program for Your Farm

How to Get Started

Contact your AGRIS agronomist for a personalized soil sampling plan. We’ll walk you through your options, demonstrate how the data is collected and used, and help you decide what method best supports your goals.

2. Grid Soil Sampling

Systematic and data-rich.

• Typically sampled at 2.5-acre intervals
• Helps detect nutrient variability across the entire field
• Excellent foundation for variable-rate lime and fertilizer applications

Best for: Farmers looking for a structured and consistent method to manage soil variability.

3. Zone Soil Sampling

Ideal for fields with consistent management zones over time.

• Uses yield maps, satellite imagery, and other field data
• Zones are stable and measurable—“If you can measure it, you can manage it.”
• Enables precision variable rate applications
• Maps created in our GIS software to guide sampling and application

Best for: Farmers who want field-specific nutrient management tailored to known productivity zones.

4. Perimeter & Composite Sampling

Efficient, simple, and 4R-compliant.

• One sample per 25 acres
• Delivers a general snapshot of soil health
• Meets minimum standards for nutrient compliance

Best for: Growers managing broad-acre fields who need a cost-effective solution.
