Do I Need a Soil Test?

Soil fertility is important for good plant growth. Testing is the only way to know nutrient levels.

A test gives you accurate informa­tion about the type and amount of fertilizer or amendment to apply. Applying proper amounts decreases runoff that can pollute waterways. This protects the envi­ronment and saves you money.

A soil test measures pH and available nutrients.Johnson County homeowners are eligible to receive one free test (Package #1)  per household per calendar year.

Proper collection of a soil sample is important for accuracy and analysis. Follow these steps for taking good samples.
