Soil PH and Analysis

Soil PH and Analysis is one of the most fundamental practices at Turfology.  It involves us pulling core samples from around your lawn and sending them off to a lab to be tested for soil pH, available nutrients, percentage of organic matter which will help us determine what needs to be altered in your program to provide optimal growing conditions for your turf.

The information provided is a key element to better understanding what exactly is happening beneath the soil surface. These tests help indicate nutrient deficiencies and pH levels of the soil. Soil testing also helps find other limiting factors that could keep your turfgrass from reaching its full potential such as Cation Exchange Capacity(CEC) Organic Matter content, and how saturated the soil is in several different nutrients.There are about 17 essential elements required for plant growth: Carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum, chlorine, and nickel.

We know, that’s a lot but each one of these plays a very important role in how your grass looks! The 3 most important nutrients for plant growth: NITROGEN, which is responsible for a strong root system and plant growth, is also one of the contributing nutrients that gives your grass that healthy, deep green color that we all love! Nitrogen is almost always present in the soil, but it may be in a form that is not available for your turfgrass to use. Adding the proper amount at the right time ensures that there is always a supply to use when needed. PHOSPHORUS’ job is to assist with the growth of the root system (you are going to hear a lot about the root system of your turfgrass, after-all, it is the most important part of the plant) and help your grass in the early stages of growth and development. POTASSIUM is the nutrient that helps prevent stress, retain water to help protect against drought, promotes “cold-hardiness”, and just like Phosphorus… helps fight against disease! Soil pH Soil pH is how we measure the acidity and alkalinity in soils.

The optimal range for pH in tall fescue turf types is between 6.0 and 6.8. If the pH is higher than 6.8 (alkaline) proper amounts of sulfur need to be added to bring that number down. If the pH is lower than a 6.0 (acidic) one of three different types of lime will be added depending on soil analysis results and nutrient levels. The most important thing to remember when adjusting the pH of your soil is patience. Depending on how far off your pH levels are, it could take several seasons to see a big change.


frequently asked question

Do you have any Questions?

Below you’ll find answers to some of the frequently asked questions. We Constantly adding most frequently asked question to this page.

1. What are common lawn diseases in the Metro East Area?

The most common types of fungal diseases in our area include brown patch, dollar spot, gray leaf spot, large patch, pythium blight, red thread, and rust.

2. How should I water my lawn to prevent disease development?

Always water your lawn in the early morning, which will allow the grass blades to dry out during the day. Watering in the evening or at night encourages disease, because of excess moisture that remains on the grass blades, combined with hot night temperatures will aid disease development.

3. Do I need to change my mowing habits to prevent disease?

Always mow at the correct height and frequency to help prevent excess thatch build up, along with always mowing with sharp mower blades.

4. Will improper fertility help diseases to develop?

Yes, when dealing with diseases year after year, it is best to have a soil test done to see what nutrients your lawn needs or has an excess of so we can alter your program accordingly and apply what is needed to provide optimal growing conditions.

5. Will the lawn recover from fungal disease damage?

Depending on the severity of the disease and which type it is, most lawns will require reseeding to thicken the lawn back up to where it was before. However if caught early enough and if controlled the lawn will recover.

6. Does the turf type matter when it comes to diseases?

Yes, All turf types are more and less susceptible to certain diseases, this is important to know when seeding your lawn. When dealing with turf type tall fescue especially it is important to seed with different variances of tall fescue, for some variants are more susceptible to one disease than another.

7. Does aeration and overseeding help with preventing disease?

Yes, it helps loosen the soil and break down thatch, which will improve the health of your lawn, and the healthier the lawn the more resilient it is against diseases.
