How To Test Your Master Turf
Soil
Generally speaking there four attributes that your local extension
service will test for when you submit a soil sample. These
are the pH level, the Phosphorus level, the Potassium level,
and the level of organic matter. Having each of these at the
recommended level is important for optimum performance in
your lawn.
- pH Level:
This is the easiest test for the homeowner to perform themselves
and one of the most critical. Grass flourishes best in soil
with a neutral to slightly acidic pH level. Grass performs
poorly in extremely acidic or alkaline soils. A pH test
kit can be used to determine the current level.

You can raise pH levels by applying lime, you can lower
pH levels by applying sulfur (Gypsum contains sulfur and
is often recommended as a soil additive). Follow label rates
to determine how much to apply to adjust the soil pH.
- Phosphorus Level:
Another important element in the soil is phosphorus. New
grass needs phosphorus to develop a strong root system.
Lawn starter fertilizers contain high levels of phosphorus,
which makes them an excellent fertilizer choice for the
initial seeding.
- Potassium Level:
An adequate level of potassium in the soil is also important
for a new lawn. Potassium improves a plant's disease resistance
and winter hardiness. Here again, lawn starter fertilizers
contain increased levels of potassium, which are essential
in the early stages of the lawn's development.
