The Case for
CU-Structural Soil™
Why do we need it, what is it, and how is it used? |
|
 |
| Urban trees
experience a litany of environmental insults: soil and
air pollution, heat loads, deicing salts, and impacts
from utilities, vehicles, and buildings. The most
significant problem that urban trees face, however, is the
lack of useable soil volume for root growth, since trees are
often an afterthought in city planning and streescape
design.
When roots encounter dense
soil, they change direction, stop growing, or adapt by
remaining abnormally close to the surface. This
superficial rooting makes urban trees more vulnerable
to drought and can cause pavement heaving.

However, if a dense
soil is waterlogged, tree roots can also rot from lack of
oxygen.
Ongoing construction, including sidewalk and road repair,
disturbs and compacts soil, crushing macropores

Loss of macropores has three negative consequences:
restricted aeration, diminished water drainage, and
creating a dense soil that is difficult for roots to
penetrate. These effects limit useable rooting space. |
| Patented
by Cornell University's Research Foundation, this new
revolutionary urban tree mix can safely support pavements
and sidewalks and is designed to provide ample rooting
area for street trees, decreasing tree mortality and
sidewalk failure. |
