#1 -- Invest
in a Pump Test!!
Is air coming out of your
nozzles? Is your well surging? Are your crops
not uniform in their growth habits? Are fewer gates
being opened than once were? This can all lead to reduced
yields and ultimately less profit. Investing in a pump
test is the first thing you should do. It
can save money, time and headaches. Shouldn't
you know what's in the ground before you start investing
larger dollars? Because the wells around you are all
fine, do not assume anything. Your investment is with
your well, not the other wells. A pump test is an excellent
indicator of current problems as well as potential problems. This
test provides you with the most current reliable flow, pressure,
and drawdown information. This information is vital
in determining if new bowls are needed, if a new well is
needed, or if the well needs to be drilled deeper. For
example, don't assume because the surrounding well water
elevations are 60 feet deep that your's is 60 feet deep. Do
it right the first time. Don't assume and have to redo
what was done because the well wasn't investigated the first
time. Later in the crop season is the optimum time
for doing pump tests while seasonal drawdown is at or near
the peak.
Pump tests are also recommended
when converting from a gravity system to a pivot or subsurface
drip system. The information is valuable for matching
pumps and motors in order to get the most efficient irrigation
system possible.
A pump test can be completed
by your well person. You can obtain and document the
results on the NRCS-ENG-85 form, "Pumping Plant Inventory
and Evaluation Worksheet." This form is available
at your local NRCS office or online at http://efotg.nrcs.usda.gov/references/public/NE/NE-ENG-85.pdf. A
sample of this form is shown below.
ACROSS THE TRI-BASIN
NRD
EQIP Dryland and
No-till Field Checks:
ASome of you may have
already noticed NRCS staff or summer interns out checking
your EQIP-funded irrigation projects for dryland and no-till
contract obligations. This week we got started in Kearney
and Phelps counties. We will continue to do these and
work our way into Gosper County. All irrigation-related
EQIP contracts signed in 2003 through 2007 with dryland and
no-till obligations will be field checked. This past
spring you all received a reminder letter with a map indicating
which areas need to be dryland and no-tilled for the 2007
crop year. Failure to comply with your EQIP contract
could result in termination, repayment of funds, plus penalties.
If you have any questions
related to this or anything else related to your EQIP contract,
contact your local NRCS office at the address or phone numbers
listed at the bottom of this newsletter.
Stage of Growth:
Corn
(16-leaf to milk stage): We are at the peak water
use stages for corn. Nitrogen and phosphorous uptake
is rapid. Environmental stress at this time can greatly
reduce yield. At blister, the kernals are at 85%
moisture and will start declining until harvest.
Soybeans
(V6 to beginning pod stage): Soybeans are heading
into the most crucial period of plant development in terms
of seed yield (full pod stage). Stress from full
pod to full seed stage will reduce yields more than the
same stress at any other period of development. Soybeans
at full bloom with 50% defoliation will reduce yield by
roughly 6%.
Irrigation:
Since we are in or heading
into the high water-use period of the growing season for
corn and soybeans, irrigation is in full force where it is
needed. Rains continue periodically in places allowing
a few days relief from irrigation demand. As summer
moves along, it seems these rains are scheduling themselves
less often. Depending upon where the rains have fallen
recently, on the outside you can't see a difference between
a lot of the dryland and irrigated crops. However,
there are areas where you can start to see a difference.
Last Thursday (July 12)
hail took its toll in areas south of Elwood. I saw
soybean fields completely stripped of leaves down to the
stems and corn with heavy amounts of leaf loss.
Lake McConaughy is at
33.5% capacity versus 29.0% a year ago. Flows in the North
Platte River at Lewellen are at 185 cfs versus 150 cfs
a year ago. Flows in the South Platte River at Roscoe are
at 87 cfs versus 0 cfs a year ago. You
can track these flows on Central's
web site.
