organic material and they no longer
function the way they're supposed
to." The exception, he says, are
streams that have healthy buffer
strips to filter out run-off and keep
cattle out of the water. Thankfully,
through government programs like
CURB, farmers have incentives to
rebuild these precious buffer strips.
The land should be protected from
erosion by heavy rainfall and wind by
shelterbelts and windbreaks
throughout the farming areas of
central North America, Kock says.
He doesn't support the classic
concept of a windbreak of two or
three rows of evergreens. "It takes up
a lot of farmland. It takes a lot of
energy to actually get it installed and
growing. Because the wind is
deflected up and over the windbreak,
there's a stagnant area downwind
from these barriers."
Air movement through plants is
important to prevent disease,
particularly in mono -culture crop, he
says. Disease germinates in moist
conditions. Because germination
takes about 12 hours, if crops can be
dried from dew early in the morning,
leaving them wet only about eight or
nine hours from the dew, the disease
spores won't have time to germinate
and infect the crop.
So permeable windbreaks are a
solution, he says. Many conifers
(with the possible exception of
Norway Spruce) may be too dense for
this. Deciduous trees, on the other
hand, slow the wind down without
blocking it. Ash, oak, walnut, cherry,
cottonwood, Manitoba maple, all
have characteristics that allow a lot of
air through but the important thing is,
rather than deflecting the wind, it
slows it. "You can hear the wind
moving through it. You hear it.
That's friction. It's that exchange of
energies we need to reduce the
velocity of the wind aria still
accommodate their flow across the
crop."
When the wind is deflected by a
thicker barrier it doesn't lose
velocity, it just goes up and over and
comes down moving as fast as ever,
sweeping over the soil and drying it
out.
In early spring deciduous trees
have no leaves, allowing the sun in to
dry the soil off so farmers can get on
the land sooner. Later, when they leaf
