Interpreting a University Soil Test for Organic Vegetables

A New Hampshire gardener received a UNH soil test report for a 5,000 sq ft organic vegetable garden and asked for interpretation, cost estimates, and sourcing advice.

Key Takeaways

• Follow the lab's recommendations—they are calibrated for local conditions.
• Lime is usually the most critical item; apply as soon as possible.
• Green manures and compost improve texture but don't replace specific nutrient amendments.
• Source amendments from a local independent garden center—they know regional products and rates.
• Cost varies widely by location; the garden center can provide estimates.

University tests are reliable; the challenge is executing the plan with quality local inputs.
