Occasionally, we recommend having a soil test done before any lawn applications are applied. This test will indicate your soil’s current pH and nutrient content, which will help determine the proper fertilization program needed to correct any nutrient deficiencies in your lawn.
In some cases, when a lawn is not responding to treatments, we recommend performing a soil analysis. A sample of your soil is sent to a lab, where it is tested to identify pH imbalance, nutrient deficiencies, and sodium levels in the soil.
These soil test results – combined with in-person inspections, proper fertilizers, aeration, and establishing proper watering practices – can help turn around an unresponsive lawn. After a soil analysis is conducted, your RYAN Pro will meet with you to go over the results and plan a course of action to correct any found issues.
Remember, pH refers to the acidity of the soil. A lower pH value means the soils is acidic and requires lime. A higher pH value means the soil is basic and might benefit from regular sulfur applications. On average, most soils in our areas have good levels of calcium (Ca), magnesium (Mg), and potassium (K) and other micronutrients like boron, copper and zinc. But through our soil testing we have found all kinds of soils with all different kinds of deficiencies. Frequently, especially in brand new suburbs, we will find that the soil is low in phosphorus (P). And many soils in our area are high in pH, which limits the availability of iron (Fe). Iron is a key component of chlorophyll (the green stuff in plants). Without iron, grass and trees like pin oaks will become yellow and eventually become weak and damaged. We want to make sure your lawn and landscape has the fertility program that your soil needs.
