Questions Answered, Why
No-tillage is different.
Emergence of Soft White Winter Wheat with
Water Injection.
No-tillage may
have very special attributes in the establishment of irrigated and
dryland crops.
No-tillage
Irrigated producers should not be irrigating their crop up.
This is a
salvage operation using pivot supplied water and provides no
competitive advantage over the weeds.
Winter
Canola requires SRS for a 99% stand in 4 days.
Note: Soil
sample of moisture content column is 2 inches to 6 inches directly
at the water injection point and under the seed.

Ninety Per
Cent of the Erosion of the Great Plains Comes From a Winter Wheat
Rotation.
We are
raising the wrong crop.
GJS.
Starting a winter wheat crop in the PNW Chemfallow rotation.
A good chance for emergence in a No-till soil. A soil with a high
CEC with excellent depth for storage of winter moisture.
Continuous Tillage through the last 130 years provides most of the
soil lost and the great erosion
events on the Great Plains. Tillage
destroyed the resource. The soil stores
about 10% to 20% of the original carbon and cannot start a fall crop
timely as it did in the early pioneering years.
From Floyd

November
1985, Water Injection at Seeding of Winter Wheat,
Noori, Bolton, Moss.
Subject, Seed
Row water injection for improving stands of winter wheat.
Winter Wheat,
Stephens, Soft White, Core samples taken. In a tillage system.
The experiment
was 18 inch spacing with a shanking type seed opener.
The non
singulated seed concentration was 60 seeds per meter of row or one
seed every 2/3 of an inch of seed row. A common non singulated
population.
Note that per
cent moisture was also tested in the seed.
Based on the
level of germination and stand quality and difference between at 65
gallons per acre on 30 inch centers. (Illustration is 18 inch and
value has been adjusted to 30 inch).
It would
appear that critical germination was reached in 12 hours with 65
gallons per acre.
Seed water
content of 36% of was achieved in 12 hours was actually increased to
46% in 48 hours.
Typically
malting barley is steeped (short soak in water) up to 50 times to
develop chit or hair like roots.
The critical
moisture level in malting barley seed is 50%.
The flushing
of ABA from the seed allows improved germination for malting barley.
The
critical seed moisture content must be maintained to flush the ABA
or Abscisic Acid, the dormancy gene builds ABA.

The Stephens Soft White winter
wheat seed (96% germ) is estimated to have a Mass
10,000 seeds per lb.
-
The Hybrid Rubisco Popular Winter
Canola planter grade seed is estimated to have a mass of 70,000
live seeds per lb.
-
The seed spacing of Winter Canola
is 5 inches singulated. The winter wheat non singulated seed rate
is 7.5 times greater in pop.
-
The mass is thus 52.5 times
greater for wheat than winter canola (.075 dia.) in
the row.
-
It would appear that the same
amount of water is required for Cotton based on research in 1979,
Fowler.
-
So the soil determines the
correct water rate…not the seed size or the number seeds or the
species.
Thus loose or
sandy, or low CEC or low OM soils may require more water if the seed
row cannot stay moist for 48 hours. Moist being 50% seed water
content or moisture in the seed.
Also higher
rates of water may be required if the soil moisture line…consistent
germinating soil moisture line is much deeper than the seed row.
No-tillage
seeding may have extreme field wide advantages over tillage systems
with inconsistent moisture lines.
Note:1
that water injection has not been reviewed for flushing of ABA
Abscisic Acid. Additives of Zinc sulfate has been utilized in Iran
with water to improve stands of Canola.
Note 2:
Dwarf Essex on 10 inch rows produced excellent stands when 150
gallons of water was injected in Palouse soils, eroded clay hilltops
performed well. 1983 to 1985 .
Note 3:
Germination starts at the point of seed placement with SRS
injection. All seeds are potentially adding to yield and competitive
weed suppression.
Sugar Beets
and Cotton, water Injection produced good results in tillage.
Producers
can proceed to higher level of efficiency by using SRS to flush ABA
from the seed row.
One of the
benefits of building good beer is Steeping to form Chit. SRS is
similar in many respects and very economical.
Bankable
yield increases for 20% to 33% and never a yield reduction.
A $50,000
investment at $5.00 acre will bring returns up to $250 additional
net income per acre in Winter Canola and Dwarf Essex.
Drive Seed Costs Down with a Yield Jump.
Seed
Row Saturation, The SRS Challenge.
Seed Row Saturation has improved with Exactrix SRS systems.
SRS takes about $40,000 to $50,000 of equipment investment to
produce a good stand in winter Canola,
Cotton,
Soybeans, Sugar Beets,
Sunflowers, Milo and Corn.
Reduce your seed costs, and seed to a uniform stand population with
Winter Canola and Soybeans.
A fantastic payoff adding up $100 to $250 per acre in winter Canola.
About 7.5% more yield in Soybeans dryland.
A potential great payoff with Corn and Milo, anytime the seed is
expensive consider SRS.
Up to 108 gallons per minute for 120 foot planters.
Looking Glass Manifolds and low hydraulic flow is now possible
Nominal Reports and Exactrix Techniques, at less than 2.5 to 3
gallons hydraulic flow per minute at 40 feet.
The Goal Being,
to make a lot of money, save soil, and carry out a rotational
soil sanitization for future crops.
You must have a great start for the best possible finish in
Winter Canola.
