Soil is the foundation for healthy grass. Most homes come with less than ideal soils. Improving your soil is the number one thing you can do to improve your lawn. It doesn’t matter whether you start with sandy loose soil or you have heavy clay soil you can improve either case by adding soil amendments.
Purpose of Soil
To better understand what we’re dealing with its helpful to remember what purpose soil serves. Soil has four important functions:
. as a medium for plant growth;
. as a means of water storage, supply and purification;
. as a modifier of the Earth’s atmosphere; and
. as a habitat for organisms
In the natural environment, all of these functions, in their turn, modify the soil.
