A soil test helps turn amendment decisions into a site-specific discussion. Your soil, compost and potting mix are not interchangeable materials.
What’s worth understanding
Soil testing can guide fertility decisions; extra nutrients are not automatically useful.
Use a suitable soil test to guide amendment decisions instead of treating soil appearance as a nutrient diagnosis.
Select sampling and interpretation appropriate to your site and crop; not all tests measure the same properties.
Take it into your growing space
- 1
Find a local soil-testing service through Extension.

Keep the lab’s interpretation with your garden plan.
Do not add fertilizer just because a plant is small or an internet recipe says to.
