How much CO2 is emitted by the machinery as it plants and harvests the corn crop?

The tractors farming it, plowing, discing, planting, fertilizing, harvesting, etc...or hauling it as picked corn, or hauling it as fuel.

Net negative CO2 emitted. Hundreds of acres of plants vs a handful of vehicles.

If only everybody was a farmer. EIEIO

Or at least owned a single plant, they might understand

EDIT, still havent answered my question, how much CO2 does oil absorb during pumping? LOL! / End conversation

No,it's not. You are attempting to compare one phase of 1 of the objects to a different phase of the 2nd object.
The growth phase of corn vs the harvest phase of oil.
The growth phase of oil was hundreds of thousands (millions?) of years ago when it was still living plants and animal life, until death, & it is then covered with soil or water for the duration of it's growth phase, usually at the bottom of the ocean and that is where it's c02 is sequestered either as icy hydrates or the plankton uses photo synthesis to convert the c02 into complex sugars.
In the transport/harvest phase, neither corn nor oil absorb much (if any) C02.
Inversely, the harvest phase of corn is when the plant is at or nearing it's end life and it's foliage begins to wither and dry.
Corn does absorb c02 during it's growth phase but it is passed down the vascular system of the stalk and sequestered in the soil. If you are going to use soil as part of the comparison, then you also have to use the 2/3 part of the globe (oceans) that sequesters far far more C02 than the tiny bit of the arable Earth that corn is grown upon.

In other words folks, it's a trick question.

While I am new here to the OT; reading through a few posts, I see that I like your outward thoughts Maryjane. And I respect that.

The only thing that I was getting at is Corn absorbs CO2 while it grows, there are far better people out there to calculate how much it absorbs vs how much it makes to turn it into fuel. But nobody can dismiss the fact that oil absorbs nothing in todays world when it is being pumped.

If you want corn fuel, you dont need anything modern... Plant corn, pluck it by hand, mix it with water, let it set for a few weeks in a ceramic kettle, once its ready burn some kindling from the woods and distil it.

I'm sure somebody will try to inform me on how difficult or impossible distilling is without modern machinery but please go back at least 4000 years and let them know first.

Where I'm at right now corn and ethanol means pig feed and moonshine. For my turbocharged truck if I could reliably get E30 fuel - 94 octane for the price of 87 I'd be ecstatic.

There is real small picture and then there is big picture.

One acre of forest absorbs more CO2 than agricultural land.

I guess that's true. I've never seen anything about forests absorbing agricultural land.
