Sunlight in corn production

SUNLIGHT in Corn Production Today’s Ethanol Plants?

A Paradigm Shift

The Solar Corridor

Rows oriented North-South to maximize sunlight falling between the twin row pairs and on the secondary crops

Corn rows spaced widely enough apart to enable sunlight to reach the lower leaves for the entire growing season

Lower leaves are exposed to sunlight

Secondary Crop

Wheat, then clover

SUNLIGHT in Corn Production Today’s Ethanol Plants?

  • Corn rows spaced far enough apart to enable sunlight to reach the lower leaves for the entire growing season

  • Enabling the bio capture of more CO2 for BioSynthesis into more photosynthate derived carbon compounds

A Paradigm Shift

Rows oriented North-South to maximize sunlight falling between the twin row pairs and on the secondary crops

Lower leaves are exposed to sunlight

  • Grow a shorter symbiotic crop on the vacated row that completes its

The new paradigm
The New Paradigm Today’s Ethanol Plants?

  • Enables the mature chloroplasts to capture more CO2 and produce more photosynthates

  • Enables the highest capacity reproductive sinks to access more photosynthates

  • Enables vegetative sinks to access more photosynthates

  • Cultivar and variety selection is site specific, production inputs then become variety specific   


Treatments
Treatments Today’s Ethanol Plants?

  • 12 Production Environments

  • 4 Hybrids (Designated A, B, C, and D)

  • 4 Plant populations

  • 3 Replications

  • RandomizedBlock Split/Split Plot design

    • 1st split by hybrid, 2nd by plant population  

  • 2 Row width entries

    • Control: Single rows on 30 or 36 inch centers

    • Treatment: Twin rows on 60 or 72 inch centers

  • All treatments were in north/south rows between 40 and 41 degrees North latitude

Floor crops and effective yields
Floor Crops and Effective Yields Today’s Ethanol Plants?

As specifically demonstrated in Solar Corridor Floor Experiments (Deichman, 20051 and US Patent #6052941, claims 2 and 4), we can produce other specifically chosen crops between the corn twin rows without a reduction in corn yield.  Our approach has always been to select crops that had no negative impact on corn yield. We have concluded that:

  • Soybeans are not a viable floor crop because of their effect on corn yields.

  • Wheat is a viable floor crop. If careful attention is given to the swath width of the wheat crop,  a full yield (per wheat acre) of what can be produced without affecting corn yield (per crop acre).

  • Therefore ½ of the Solar Corridor crop acre can be assigned to corn, and the other ½ to a viable floor crop such as wheat.

  • The effective yields per corn acre are therefore exactly double the yields per crop acre reported on the previous charts.

Using the Solar Corridor System, each of the hybrids B, C, & D yielded 192 or more bushels per crop acre (384 bushels per effective corn acre), enough for today's ethanol plants to produce 1000 gallons of ethanol (assuming 2.65 gallons/bushel yield).


Summary and conclusions
Summary and Conclusions Today’s Ethanol Plants?

  • Increased productivity can be achieved through the utilization of the Solar Corridor System

  • Sunlight is made available to more chloroplasts to produce more carbohydrates to meet sink demands through physiological maturity

  • Appropriately selected site specific supporting practices maximize Solar Corridor benefits

    • Increased Yield, Reduced Lodging

    • Increased Sequestration of CO2

  • Solar Corridor floor crop harvest options do exist

    • We need to further develop and refine these options


Summary and conclusions cont
Summary and Today’s Ethanol Plants?Conclusions (cont.)

Based on the performance data presented, the increased biosynthesis of the atmospheric CO2 currently available in the US heartland resulting from the full deployment of the proposed new paradigm:

  • Can produce another 30bb annual gal of anhydrous equivalent alcohol fuels,

  • Plus significant quantities of clean substitutes for diesel fuel, glycerol, methane to power electric generators, high energy protein, etc.,

  • Without using any of our current food supply, cellulosic feedstock, or increasing corn (or total crop) acres,

  • While increasing sequestration of CO2.
