We need to offer farmers something else (I'm trying to finish a piece on this right now).
Well the farmers in Afganistan couldn't make money with normal crops so they raised Poppies.

Farmers in Colombia could make money with Normal crops so they raised Coca Leaf.

Maybe the Midwest farmers who can't make money raising corn could raise Hemp?

But if they did,  How would the CIA increase it's slush fund income like they do controlling the other two examples??

They could corner the US 'Munchies' markets..
It used to be the gathering of solar energy on a farm provided not only food but fibers.  (and stored energy like wood)   Fibers used in clothes, constuction, making storage containers, furnature, et la.

The demand for the 'fiber' part was destroyed by the (many times better) fiber-from-oil market.  

For the farmers to start winning again, they'd have to produce products which, when their labor is added, exceed the value of old stored sunlight.     Good luck on a solution everyone will find as likeable as the 50 year+ model of oil-> food and oil-> fibers.  Good luck on finding a solution that is just as good per acre for the small 40 acre operators as it is for the 400, 4,000 or 40,000 acre operation.

The inherent problem with agriculture is that, ultimately, all markets are finite.  Typically, it is only the inovators who make money when they establish a home/market for their crops.  There are countless examples of speciality agriculture collapsing as the market became saturated;  kiwis, llamas, emus, wine grapes, etc.  

A current example is organic crops.  Years ago organic growers were the odd balls of agriculture with a limited market - but they made money.  However, as the market has grown, the initiators are being forced out as large-scale organic operations are taking over the organic market. In essence, organic crops are becoming a commodity, not a specialty.  

Years ago I was a small-scale, certified organic grower.  We had the local market to ourselves.  However, we reached a point where we had to either spend a lot of money (mostly for additional greenhouse space) to expand our production or quit. Expansion was necessary to make more than day wages by selling in other towns.  As we looked at the capital cost, the cost of hiring people and the transportation cost to additional towns, we said the risk/reward ratio wasn't worth it.  We shut down.

Sure, there are still niche markets out there such as producing native plant seed but this won't help production agriculture.  There is no good answer.

I find this ironic in the extreme. The cheap fossil fuels are making it hard to maintain a local-market-driven small business, even if that small business is dedicated to getting away from dependency on the fossil-fuel driven society. Local organic produce may only find a more permanent niche as fossil fuel gets scarce enough to really impact the transportation industry that enables the globalization (centralization) of all economies.
All markets are finite? Maybe in the short term. Arable land is finite. There is a limit to crop yield, especially without fossil fuel-derived additives to the soil. People can only eat so much, but then the population keeps on breeding.

Biofuels changes the game. Demand for gas for the car could swallow everything farmers could grow. Of course, with the ensuing mass starvation, demand might be lessened. Perhaps you're right after all.

You just brushed past the kernel of what I'm writing about.  More later.
JB,

It's unclear what your point is; even corn for ethanol is finite.  I get the impression that you don't understand production ag.  What will happen, just like llamas and wine grapes, is that farmers will switch out of a corn and beans rotation to corn on corn and create a glut of corn.  This will drive the price of corn down and beans up so...

At the same time, by switching to corn on corn, their cost of production will go up since they won't have the residual nitrogen from the beans, possibly have to irrigate more, be paying for GM seed and their profits will likely go down short of an explosive increase in their corn price.  This is why so many farm wives work off the farm (and do the farm's books in their spare time) - to balance the variability of income and, maybe, get some benefits like medical.  You got to ask yourself, if farming is so great a profit center why does the farmer's wife work as the elementary school secretary?

But, I was addressing profitable farming in my initial response.  Growing commodity crops is like being a slave to the bank because it is often impossible to plow down and plant crops without a loan each year.

Is overseas demand going to make a difference to farm profitibility?  How are these countries with starving people going to pay for it?  Via our tax dollars to subsidize it all?  Are US consumers going to watch the price of food go up because the .gov mandates ethanol?  How about the reality that new engines aren't tricked into better emissions because of the oxygenates added to gasoline?

In my county, I know of quality wine grape growers who didn't pick last year because they couldn't find a home for their grapes that turned a profit.  The same thing will happen to corn growers.

I don't know the answer.

Todd;  a Realist

They don't have to stop crop rotations. Corn, then beans, then corn, etc.

My point is this:

Corn and soybeans are currently commodities because there has been an overproduction relative to world demand. Subsidies paid to farmers for these make things worse for everybody except ADM and Cargill. Farmers get hosed because they take all the risk and are usually in debt for equipment, land, etc. I'm not an ag expert, but my dad grew up on one and I have plenty of close relatives in Illinois that farm including a cousin that does pretty well. But most do work other jobs. That is the present, though. I'm talking about the next few years, and farmers are excited about a huge new market for their produc. Who can blame them?

There is currently under construction in western Washington a biodiesel plant capable of churning out 100 M gallons of product per year. Similar things are unfolding in Iowa and elsewhere. I added a few of them up and came to 1.2 billion gallon capacity in the next couple of years. Assuming they all use soybeans, that would use a third of the current US crop. But even that much biodiesel doesn't make much of a dent in the amount of diesel fuel consumed in the US. Same for ethanol, assuming that the EROEI really is 1.2 or so. Energy consumption is like a black hole--it will swallow everything and not so much burp.

I'm not saying things will turn out good for farmers, as it rarely does.

JB,

I guess we are coming from the same place in most ways - at least we aren't arguing about basics.

I believe that farmers are going to take it by over producing.  You may be right that they have a few good years ahead. I just believe that farm profits, in the long run, won't come from producing commodtity crops regardless of their demand.

My rationale for this is that consumers are going to whoop and howler about farm "subsidies" just like oil profits if it hits them in the pocketbook.  We'll see.

Todd; a Realist

I wonder whether the real value of biodiesel will be as an additive to replace the lubricity lost in low sulphur diesel.  We will probably be close to peak ethanol when there is enough for 90/10 gasohol.  
We'd be better off using ethanol as a co-injected octane booster than blending it with gasoline; savings of 30% aren't enough to save us, but are nothing to sneeze at either.  If we're going to use ethanol with petroleum, that's how it should be used.
I expect that you are right that 90/10 ethanol on a global aggregate basis is probably peak ethanol. In fact, it may be even lower since it does not appear that temperate countries can produce ethanol at efficiencies adequate to justify their use.

However, offsetting 10% of gasoline use with a sustainable, climate friendly fuel such as sugar cane derived ethanol is exactly the type of step we need to take to completely solve peak oil and global warming. 3-4 more silver bul;ets of the same magnitude and peak oil would be a lot less of a worry.

fiber from oil ?    you must be talking about vinyl   is there anything made of vinyl that is worth a shit  ?
Not just vinyl.  Synthetic fibers like nylon, lycra and polyester.
Is there anything made of polyester that is worth a shit?
Hmmm. Nylon makes good casings for bicycle tires. I remember tyres of silk, cotton, and linen, Nylon just as good, or better.
OTOH I have a new silk scarf. Handloomed, wild-gathered silk, vegetable dyes, that sort of thing. Not only do I get looks and compliments, total strangers walk up and want to touch it. You won't get that from oily products.
You won't get that from oily products.

I think you'd be surprised.    

Today's polyester is nothing like the kind that was infamous in the '70s.  You'd never know it was polyester.

And I'm going to miss microfiber if it gets too expensive for ordinary peons.  It's much better than cotton for athletic wear, because it wicks moisture away from the skin.  And I love microfiber dusting cloths.  

Then there's nylon stockings...

Oh you tease.
gimme cotton  gimme wool   gimme linen   gimme weed   er   i mean  gimme hemp   but gimme zero % polyester
there otta be a law again lycra (for some people)   and polyester       that is soooooooooo   disco  see www.liesuresuitlarry for details
I have suggested alfalfa and rabbit ranching. Think of it a perennial nitrogen fixing crop, great protein conversion and reproduction rate.

And the raptors and coyotes would love it too. Need to develop some new products though like Kentucky fried rabbit and maybe buffalo ears.

Seriously though Iowa and the corn belt have seasonal rains and fertile soils. Their production potential for summer  vegetable production and for decentralized grain/meat as crop has been displaced by longer seasons in
California, industrialization of meat production, cheap energy and transportation.

My take on this situation is that it is a temporary situation and that energy futures will neutralize this subsidy driven corn/ethanol market for grain.

Best

real simple solution.
offer them twice as much to use that land for food rather then making fuel.
Offer them enough for their byproducts that they can hold on by selling what they can make from their corn stover, wheat and rice straw, spoiled grain, etc.  If the floor price is set by the warming-abatement payment for the sequestered carbon, there's no way for the commodity price to fall below that.
