(Dr. Jaradat) We live in a world of salt, but we do not recognize it.

(Dr. Cihacek) Once it's salinated, you got a problem.

(Dr. Hopkins) One of the points that many, many farmers have said is

that they'd never witnessed problems before.

(Harold Steppuhn) If I'm a producer and on my ground,

I've got a problem with it-- it's not overblown--

is made possible by an EPA Section 319 grant

administered by the North Dakota Department of Health.

Resource Conservation and Development Councils,

It went from, I would say 5% to 10% of the farm acres

being affected by salinity to up to 40% to 50%.

Salinity isn't a new problem, it's a worldwide problem

(Matt Olien, narrator) If you've driven by farm fields in the Upper Great Plains,

you've no doubt noticed patches of white,

chalky soil, usually near roads and ditches,

It's soil salinity, too much salt in the soil,

to grow a productive crop in those areas.

Overall reduced soil health, so compaction issues,

you're using for management-- if you're using

conventional tillage or no till or strip till.

All of my producers are very concerned about it

and are actively looking for answers and trying new things

trying some crop rotations, trying some limited drainage

So the producer is going to try to pick the crop

that gives him the best option and economic return.

(narrator) Excess Salinity is caused generally

by too wet of conditions resulting in a high water table.

Most agree the problem in the Upper Great Plains

when the dry cycle converted to a wet cycle and has never left.

But the problem has been around for centuries.

(Dr. Jaradat) The land in Mesopotamia is very flat,

and irrigating that land created problems

and high evaporation from the irrigated water.

Salts became concentrated, and the irrigation water

coming from the twin rivers, the Tigris and Euphrates,

enriched that salt in the Mesopotamia plain,

of lower Mesopotamia turned into white crusts.

so it's been going on for a long period of time.

A lot of our soils were pushed in here by the glaciers,

So as these salts weather-- they're young materials;

there's a lot of things to weather in there.

Then wherever the water goes, they carry these salt minerals.

(Dr. Abdullah) Although it is a problem here,

to the salinity problem in other parts of the world.

Just to give you an example-- California,

and there are 200 million hectares of saline land

which is not producing up to its productive capacity.

especially after the construction of the Aswan Dam.

this kind of natural remedy, so to speak,

of soil fertility and handling salinity stopped abruptly.

Based on that, in fact, major health problems were created.

(narrator) In our region, the topography of the land
