“Soil test strips are an easy and affordable way to test your soil’s pH level, as well as its levels of nitrogen, phosphorus and potassium,” says Lina Cowley, an avid outdoor expert and editor at TrimmedRoots.com. “But not all soil test strips are created equal. Look for soil test strips that have been independently verified for accuracy. You want to make sure that your soil test strips are giving you accurate readings so that you can make informed decisions about how to improve your soil.”

Home soil test kits guide gardeners to the right types and quantities of fertilizers to optimize specific plant growth by revealing pH, which indicates acidity or alkalinity. The tests can identify soil contaminants, too.

I thought I was taking good care of my lawn, water two times per week, fertilize two times per summer, mow weekly,” writes five-star reviewer, Rick Crouch. “Tests results showed my lawn was below the acceptable range in all nutrients except calcium, which was three times what it should be (due to excessive amounts of limestone) and high pH. I am now taking an aggressive action to amend the compacted clay soil with core aeration, applying compost top dressing and following the recommended guidelines for fertilizer applications at the rate to get my stressed lawn healthy. I should have done this 15 years ago. Lawn is looking much better after eight weeks.”
