Supporting the Right Source and Right Rate
Healthy soils are the foundation of nutrient stewardship. Soil testing helps farmers apply the right inputs, while soil health practices build long-term productivity.
What It Is
Soil testing measures the nutrients already available in your fields, ensuring you don’t apply more than you need. Combined with soil health practices like reduced tillage, cover crops, and organic matter management, testing provides the data to make better decisions for both yield and sustainability.
What to Expect
- Accurate nutrient data → Soil tests identify existing nutrient levels, helping you choose the right source and rate for your crops.
- Healthier soils → Practices like adding organic matter, maintaining living roots, and reducing disturbance improve nutrient retention.
- Better ROI → Applying only what’s needed saves money on inputs while protecting water quality.
Proven Benefits
- Soil testing supports the Right Source by matching fertilizers to crop needs and soil nutrient supply.
- Regular testing avoids over-application of phosphorus and potassium, which protects waterways.
- Soil health practices increase organic matter, boosting water-holding capacity and nutrient cycling.
Soil Health in Action
- Farms using cover crops and reduced tillage see improved infiltration and reduced runoff.
- Higher organic matter levels mean soils can hold more water and nutrients during dry periods.
- Building soil biology supports long-term productivity and resilience.
Getting Started
- Work with your local Extension service or advisor to set up a soil testing schedule.
- Choose soil health practices that align with your farm goals — from cover crops to reduced tillage.
- Track changes over time to measure improvements in both soil fertility and resilience.
