Why Is Good Soil Important?

 

Why Is Good Soil Important?
For optimum growth, turfgrass needs just four things (in the proper balance)…sunlight, air, water and nutrients.  Reduce any of these, or provide too much of any one and the turfgrass will suffer or die. In the right proportions, turfgrass will flourish, providing beauty to the landscape, a clean and safe place to play, plus many other benefits.
 
Grass obtains three of the four essential factors (air, water, and nutrients) from the soil, but many soils are less than ideal for growing grass. Some soils contain too much clay and may be compacted. While compacted soils may be great for roads they are bad for grass. If air and water are not available to the roots it will inhibit the growth of the grass. Other soils may have too much sand. While sand may be beautiful on a beach, too much sand in the soil will prevent water and nutrients from staying in the root zone long enough for the plant to use them. Another frequently observed problem with many soils is the pH.  The pH scale measures how acidic or basic a substance is. If the degree of acidity or alkalinity in the soil is too high or too low it can affect the availability of nutrients to the plant and prevent optimum growth.
