Hybrid development allows yield maintenance
Continued from A17
different varieties of corn through-
out a field depending on the charac-
teristics of the land.
"Eventually, the machinery could
carry seeds better suited to dry or
wet areas."
Another advantage to reduced
fertilizer application may be the
gradual improvement of the quality
of the land.
Large amounts of fertilizer and
extensive tillage have destroyed the
desirable qualities in the land, says
Mr. Shillinglaw.
"We may have already caused the
loss of 30 per cent of organic mat-
ter."
"The tremendous development in
hybrids has allowed us to maintain
yields."
The return to no-till farming has
returned some of the yield poten
tial. Old micro-organisms which
feed the soil are returning, as they
could only survive in undisturbed
soils, he says.
One of the factors of GPS which
limits participation thus far is the
cost.
The price of the entire setup,
including yield monitor, global
positioning system, computer and
software can add up to more than
$11,000.
Some of the equipment can be
eliminated by walking the land,
mapping it without the satellite and
using the computer to compare
yields with location.
The support services are also an
area of concern.
There is a need for more person-
nel able to input and interpret the
data, says Mr. Shillinglaw.
The limited number of farmers
using the system, who may wish to
have the services of a planter which
can utilize the computerized map-
ping for fertilizer application, is
also a deterrent for companies to
become involved, says Mr.Wheel-
er.
"The cost output to purchase
machinery could not be recouped
by one or two users as the rental
cost would be unreasonable for
them to cover."
Mr. Wheeler agrees that walking
the land regularly will tell the
farmer of problem areas without
the need of the satellite system.
The cost of the technology is not
yet at the level where the average
farmer could make use of it, he
says.
Both Mr. Shillinglaw and Mr.
Wheeler agree that GPS is an inno-
vation to watch in the coming
years, as more data is acquired and
refinements to the system occur.
As the use of yield monitors and
field, mapping become more wide
spread, the agricultural supply
industry may be more willing to
invest in the technology, offering it
for rent instead of making the pur-
chase of equipment necessary for
the individual.
