growing/sourcing/delivery of peas for livestock in the midwest in a drought year

There are a few great, long-standing, regenerative farms around Wichita, KS.

One of the absolute best is our friends' farm, JAKO, in Hutchinson.  They raise healthy animals, specializing in cattle, sheep, chickens, pigs, and dairy.  They leverage solar for energy, and have developed a fantastic electric fencing system, with simple corners and drive-over gates.  They are good people who have been caring for this chunk of earth longer than I've been alive.

Like much of our region, they're in drought. Their animals are healthy and coping well, but sourcing supplemental feed that meets their ethical criteria is hard at the moment, particularly with the shortage of this years' regional supply of peas.  They've had to look all the way up to North Dakota to find what is usually available here in state.

So the questions are:
-Does anyone out there have input on long-haul delivery of grain crops from N. Dakota to Kansas?  Train may be an option, as there's a prominant rail line that runs through Hutchinson.
-Does anyone out there have any leads on other sources of peas?  Organic soy is a last resort.

And my big question -
-If I were to sow say, 70 acres of field peas next year, and we have heat and drought like this year, what can increase my chances of success?

Some thoughts:
-get my swales and terraces installed/improved prior to sowing
-choose/develop heat-tolerant varieties
-choose/develop varieties that reach maturity quickly
-try sowing prior to last frost date.
-Sow it in clay balls, Fukuoka-style, so it doesn't germinate until rainfall
-mixes, like cowpeas/buckwheat/millet
-try illionois bundleflower as an alternative, harvested and baled as a leguminous hay

What else?  



Here's a decent list of varieties.  I would avoid the hybrids.

Read the book, 'grapes of wrath' by  John Steinbeck for a background history.
Also, how do you 'leverage solar'?
Are there any old timers about, they may have good knowledge, what have you been doing about increasing the amount if organic matter in the soil previously?
Shifting fodder long distances may not fit in with the concept looking after the property,
sometimes you have to reduce the stock numbers.
Are there any water courses where you are? Without taking water from a river there are ways to help the land using Natural Farming Sequence.
Its about preserving water in the soil.
