| Quick Fact: -------
Why Is Good Soil Important?
For optimum growth, turfgrass needs just four things (in
the proper balance) to grow...sunlight, air, water and nutrients.
Reduce any of these, or provide too much of any one, and
the grass may die or simply suffer. In the right proportions,
the grass will flourish, providing not only beauty to the
landscape, but also a clean and safe place to play and many
benefits to the environment.
Grass obtains three of these 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 very compacted... great for roads, bad for
grass, because air and water aren't available to the roots
and the roots can't grow. Other soils may have too much
sand... beautiful on a beach, but difficult to grow grass
because water and nutrients won't stay in the root zone
long enough for the plant to use. Another frequently observed
problem with many soils is that its pH (the degree of acidity
or alkalinity) is too high or two low for optimum grass
growth.
Quick Fact: ------- What Is The Best
Soil For Turfgrass?
Loams, sandy loams and loamy sands, with a pH of 6.0 to
7.0 are the very best soils for producing a beautiful, high-use,
low-maintenance lawn. Unfortunately, this ideal soil mixture
is seldom found on any property after construction.
Quick Fact: ------- How Deep Should
the Soil Be For Turfgrass?
The absolute minimum soil depth for a care-free lawn is
10 cm; however, for deeper root penetration and the benefits
that brings, the accepted standard is 15 cm.
Quick Fact: ------- Can Soils Be Improved?
Practically without exception, not only can most soils be
improved, they usually need to be improved to obtain the
maximum results with only a minimum of other on-going effort.
The knowledge of what is necessary, the amount and availability
of materials and the immediate costs of time and money are
the factors that typically deter people from taking the
steps necessary to improving the soil. While some people
do not fully understand the importance of good soils for
grass, many also believe they can save time and money by
ignoring the need to improve their lawn's soil.
The fact is that failing to improve the soil before planting
is only inviting a much greater and continual investment
of both time and money, that will never return its value
as fully as preparing the soil properly before planting
any grass. |
