Testing your soil is a fundamental part of understanding lawn care. Think of it like a diagnosis at the doctors — they need to work out what’s wrong with you before prescribing treatment. To get a golf course lawn, you need the information required to achieve it. A soil test kit for your lawn is easy to use, with results available within a week — so you can know which nutrients your soil lacks early on. 

Soil test kits and pH adjustments can save you time and money on lawn fertilizer applications and biostimulants. Proper soil pH is an essential parameter for maximizing nutrient uptake in your grass. One small investment can have you right on track to being the envy of your neighborhood.

What should my soil pH be?

All soil is either more alkaline or acidic on the pH scale, dependent on your location. The ideal soil pH should be a neutral pH of six to seven. If your soil has a pH reading that’s below or above six or seven, you’ll need to get a pH soil adjustment to raise or lower your soil’s pH.

What happens if soil pH is too low or too high?

When your soil’s pH is too low or high, grass will struggle to absorb nutrients through its root system. As a result, nutrient deficiencies can lead to yellow turf and stunted growth. But, certain grass types have their own ideal pH range, and some thrive in acidic or alkaline soil. We recommend researching your grass type before conducting a soil test to determine which nutrients would best supplement your lawn.

What kind of fertilizer does my lawn need?

Your grass needs three key macronutrients in large amounts to feed your lawn and keep it in top condition. Micronutrients are the opposite and are what your soil needs in lesser amounts. If you find after using your soil test kit that your lawn lacks certain micronutrients, use NutriSolve.

Nitrogen, phosphorus, and potassium are the holy trinities of macronutrients. Nitrogen is a chlorophyll component, providing grass with a healthy green color. If your grass is yellow and brittle, it’s probably lacking in nitrogen, and, as a result, is more susceptible to disease. Phosphorus strengthens the root system, and potassium promotes healthy grass growth. You’ll notice on most bags of fertilizer that all three of these nutrients are abbreviated to “NPK,” with a number above each letter. This number will indicate how much macronutrient is supplemented in a particular fertilizer.

Lawn Soil Test Kit and pH Adjustment FAQs

If you’re unfamiliar with soil test kits and pH adjustments, we’ve put together a few frequently asked questions to help you on your way. For more specialist lawn-care tips and tricks, head to our blog or subscribe to our YouTube channel.

How do I adjust soil pH?

First things first, get the results of your lawn soil test kit in before you start adjusting soil pH levels. Lawns thrive in slightly acidic to neutral soil with pH levels between 6.2 and 7. If your soil shows a high alkaline pH reading, you’ll need a product like MAG-I-CAL® PLUS from Jonathan Green to lower your pH. It contains sulfur and calcium sulfate dihydrate to aid cell development and helps loosen hard soils to increase porosity. When soil is too alkaline and compacted, vital water, air, and nutrients can’t be absorbed by grass roots effectively — leading to weak, spindly grass.

To raise pH levels in your soil, Jonathan Green offers another product by the same name: MAG-I-CAL® PLUS. It contains calcium carbonate in a soluble form that boosts your soil’s pH levels. It’s important to remember that proper soil pH and loose, biologically active soil are the winning combinations to achieving a golf course lawn.
