Irrigation Efficiency Research in the Oklahoma Panhandle

(folk music)

>>> Hello everyone, and welcome to SUNUP.

I'm Lyndall Stout.

One of the world's largest aquifers, the Ogallala,

is found in the Great Plains and lies in part

in the Oklahoma Panhandle.

Scientists from OSU and several other universities

are finding solutions to sustain this crucial water source.

Today, SUNUP's Dave Deken talks with our

extension water conservation specialist Jason Warren

about using technology to get the most from irrigation.

 

>>> We're up here in the Panhandle just south of

Elkhart, Kansas and Jason, you guys are doing some research

on irrigation.

>>> Yeah, this, we're standing on our

McCaull Research and Demonstration Farm.

So what we're doing here is large scale

research and demonstration,

trying to utilize commercially available products

like aerial imagery and irrigation management tools

and slow moisture sensors

to see how we can improve our nitrogen management

which improves our profitability,

and then how we can improve and maximize

the water productivity and the water

we got left in the ground here.

>>> Because it does come down to the water down in the aquifer

and using it more efficiently.

>>> Yeah, and so, this farm, we're running three pivots here

and they share three wells,

and those three wells can produce 900 gallons a minute

without a lot of trouble, and that's just,

you can't run three pivots on it.

So we rotate crops, we split pivots up into more than

one crop on the inside and out

and then we adjust the nozzle packages

and try to fit that to populations and hybrids.

And that's the same thing growers are doing.

And then what Brian and all and I are looking at,

with some help from guys like Phillip Alderman

and I got a post doc out here

is trying to look at how we can

use the technology available on our cell phones

or from airplanes or satellites to fine tune that management

to squeeze as many bushels out of the water we have.

And we've got, you know, things we're looking at

like bubblers out on the pivot to see

if we can just bubble it on 60 and spacing,

and just irrigate two rows at a time

between each of those rows instead of spreading it out

and that increases efficiency,

so there's a lot of stuff going on here.

>>> And with that, you're able to really break down the circle

because you're able to replicate it as

no technology versus extensive technology.

>>> Yeah, and there's another cool project,

like we've got plots out here that are 40 feet wide

and two to 300 feet long.

And those are used for a project where producers,

every time the pivot turns the producer tells me

how much water they want or how much nitrogen they want

when we fertigate, and so we can compare the six producers'

management strategies to one another and see what provides

an optimum profitability and productivity and whatnot,

but it's been real eye opening to see how each of them

have different management strategies,

and it'll be real fascinating to see

what the productivity is and water use efficiency,

and nitrogen efficiency, and then profitability on that.

That's what this variable rate irrigation system

allows us to do.

>>> A lot of that is technology that can be monitored

anywhere around the world, and you're able to make

adjustments, like you said.

>>> Yeah, I can, I can change the speed of the pivot,

I can change the pressure on my electric well with my phone

and then if I want to change the settings on the

variable rate irrigation I can pull my laptop out here in

the field and just click on a polygon and a map

and it'll change that,

the volume of water going out per minute.

And so in these soils, we want to put out at least

an inch and a quarter if not more per application

because the more you put out in one event

the more deeply it can infiltrate the soil without

being lost to evaporation.

So we try to maximize the amount we put out per pass

and minimize the passes without the crop going stressed

or over watering the soil when we actually get it.

So there's a lot of stuff going on, to optimization.

>>> And with that efficiency, it is water efficiency

but also it is bottom line efficiency for the producers.

>>> And there's a lot of stuff going on,

a lot of moving parts and so, when growers are asked

to use this technology 20 years ago

'cause it's been around for a long time,

it was just a struggle and quality of life deal,

where it was just one more thing.

And now, what we're doing is getting' technology

that's mobile on your phone,

that guys can see instantaneously what their field is doing

and so, you're seeing a lot more adoption.

And what we're trying to do is gettin' a large scale farm

to a condition where we can do

high-intensity research here and collect information

that these growers out here need

to optimize their water use and profitability.

>>> Okay, thank you very much, Jason Warren,

soil and water conservation specialist

here at Oklahoma State University.

(upbeat country music)

 

Mesonet Weather

>>> Hi, Wes Lee, with your weekly Mesonet weather report.

Warmer that normal temperatures have been rare in 2019.

Five of the previous six months were well below average.

This week, that changed as heat problems became an issue.

Heat advisories were issued on Monday

and continued for the week.

Recorded high temperatures were not that far off

of the normal for this time of year of 91 degrees,

so why were the heat advisories issued?

The answer is the incredible amount of moisture

in the air associated with the heat.

We are seeing relative humidity levels on Monday afternoon

that were reaching into the 60s and 70s almost statewide.

There are a couple of ways of looking at

the felt temperature that includes

this humidity into the equation.

The most popular is the heat index.

Heat index numbers on Monday

reached into the 100s across the state

and as high as 107 degrees in the Southeast counties

of Pushmataha and McCurtain.

There is another method of looking at felt temperatures

called the wet-bulb globe temperature risk.

It is similar to the heat index,

but it also takes into account

the impacts of sunlight intensity and winds on humans.

It is considered by many to be the best method

of determining heat stress.

On Monday, most of eastern Oklahoma was in the highest

risk category, indicated by black on this map.

Now, here's Gary with more on summertime temperatures.

>>> Thanks Wes, and good morning everyone.

Well, we're definitely in the dog days of summer,

the doldrums, same thing day after day,

although, we are getting a bit of rain here and there,

but of course, it's hot.

It's not too bad, but it's still hot.

And regardless of whether we're above normal

or below normal in Oklahoma, the summer is generally hot.

Now, if we look at the climatology based on, again,

that long-term average from the Oklahoma Mesonet 2004, 2018,

we can see we probably have

about another month to go on average.

August ninth or 10th, that's when we start to see

that downhill slide start of temperatures

and these are, of course,

high temperatures where we transform

from the 90s in July and August,

down into the 80s as we get into September,

and then, we plunge down into the 50s,

with some 40s in there somewhere,

as we get into the winter months.

So we have still have a little bit of ways to go

before we start to get into that cooler fall type weather.

Nothing shocking there.

Now, we look at the long-term average of rainfall,

we see that, easily, the rainiest time of the year

is, of course, our spring rainy season,

late April through mid-June,

and then, we cut down rather dramatically

as we get into July.

A few spikes there from some dramatic rainfall events,

but we can see that general decline

as we go through the summer months

and then, a little bit of a rebound

as we get into the fall months.

That's our secondary rainy season.

And then, again, we decline as we start

to get into the winter months.

That's it for this time.

We'll see you next time on the Mesonet Weather Report.

(calm rock music)

 

Summer Crop Update

>>> We're here now with Josh Lofton,

our extension cropping system specialist,

and Josh, you're hearing from producers.

They're a little worried that their crops,

their summer crops are looking drought stressed.

Let's sort that out.

>>> Yeah, I mean we're starting to get towards

those dog days of summer and it's gettin' warm,

it's gettin' a little dry out there.

We have had some parts of the state still get

periodic rain showers, but a bulk majority of the state

has been dry over the last couple weeks,

so we're starting to see that effect

on the crops as we go.

>>> But, are they really drought stressed?

I mean, what is the real scenario there?

Because we've gotten a lot of rain,

significant rain, this spring.

>>> Yeah, and almost that, and it really depends.

All that rain we got a couple of months ago

almost lulls you into a false sense of security.

If you actually dig down in a lot of these fields,

we have substantial amount of subsoil moisture.

We have a lot of moisture still present down there,

unfortunately, what happened is,

as these crops, a lot of our summer crops

that were planted a little early, they just didn't get

the root system developed they normally would.

So even if you have a lot of moisture down low,

your crop could be getting a little dry

and a little drought stressed because it just doesn't have

the root stretched down there far enough yet.

So the more and more stressed it gets,

the more it could stretch down a little bit further.

However, some of our summer crops

that are a little more developed, a little further along,

they might not get as much root growth,

and so they might get a little dry and show those signs

of drought stress for more prolonged,

during those really hot, dry periods

that we're experiencing now.

>>> Well speaking of that,

how are the crops really reacting to this sudden onset

of these 95, 100 degree days we're seeing?

>>> Yeah, it really caught us,

we were 80s a couple weeks ago

and now we're looking down the next week,

looking in the high 90s, up to 100 in some places.

So we are getting that way.

The big concern we have is a lot of our crops

that were planted kind of early

to a little on the later side

are going through reproductive growth.

They're starting to flower, a lot of our corn is tasseling

and really starting to pollinate.

Those crops that are going through that point in time,

we really have concerns about mis-pollination

or just not getting true pollination of those.

Our growers need to look at that

because the ear might look really good

but the actual kernels within them,

they won't have successfully pollinated,

and so you start seeing some gaps or some skips,

especially in these big 100 degree days,

that's gonna be the other issue.

Sorghum is starting to go through that pollination,

we're very concerned about that.

The other thing we see with sorghum

is over in the late afternoon,

you'll start to see sorghum kind of start wrapping up

its leaves and we'll start to see growers

kind of take pictures on Twitter and all that

about their leaves looking a little rolled

during the later parts in the afternoon.

That's okay, that's part of what that crop does,

it's trying to mitigate itself from those 100 degree,

it's decreasing that surface area,

kind of rolling itself up,

as long as we're not rolled up

at eight or nine o'clock in the morning,

or deeper in the evening, we're okay.

If they unfurl in the morning, we're still in a good spot.

At three or four o'clock in the afternoon,

it's probably not a good time on a 100 degree day

to check and see if you're in drought stress.

Go out there at eight or nine o'clock in the morning

when we got cooler temperatures, the humidity's up,

and see if that crop is still rolled up,

we're really concerned with that.

If it's opened like we see a lot of these leaves back here

where they're fully open, they're fully expanded,

we're still okay.

So that's kind of,

you're going back and forth on where it is,

look for that drought stress earlier in the morning.

If it's still rolled up,

then you have something to be concerned about.

>>> Let's talk about insect pressure now.

That's kind of come on suddenly, too,

the way I understand it.

What do you see?

>>> Yeah, I was sitting there watching the show

a couple weeks ago, and Tom was talking

about how there's some out there.

And we see some indication of what he was talking about,

some of these bullet hole heaves,

with the worms we've had in some of our grassy crops.

But what we're starting to see in,

is we got our first indication of sugarcane aphids

in the Southwest part of the state this week.

So that's something that growers down there,

and as they start to work north,

that they need to be scouting for.

The other thing is, for our soybean producers.

We're starting to see a lot more of the worms

and caterpillars move into soybean, and we started seeing

a lot of stink bugs show up in soybean.

So right as soon as those soybeans are flowering,

starting to set pods,

that's where we can lose a lot of yield really early,

is if we let those foliar feeding insects

and those pod feeding insects

get at those really small pods as they're developing.

So growers need to get out there,

get their sweet nets out, get their checking boots on,

cause it's time to get out in your summer crops.

I know it's not an enjoyable thing

to get out here in the 100 degrees,

but as we're starting to get weed out,

it's time to start getting in our other crops

and start checking because we definitely

have some pressure starting to build from our insect pests.

>>> Okay, well we appreciate the update Josh,

and we'll see you again soon.

>>> Thank you.

>>> Thanks.

(upbeat country music)

 

Cow-Calf Corner

>>> As we approach the middle part of July

and especially as we go on into August,

we'll probably hear from our weather man

those four little words that most Oklahomans

would just really assume not hear.

And that's high pressure heat dome.

And that's the time, of course,

when we'll have those very,

very warm temperatures day after day after day,

high 90s approaching 100 degrees,

and night time lows, maybe only down to about 80 degrees.

That's a time when, basically, our cattle out in pastures

are experiencing some level of heat stress.

And that's important from the standpoint

of especially reproduction.

We know from research that's been done

that heat stressed bulls will have a pretty substantial

decrease in semen quality and therefore their ability

to get cows bred.

On the female side work done here

at Oklahoma State University back in the '80s

showed that heat-stressed heifers or cows

that had recently been bred

showed a severe reduction in embryo survival.

Especially within that first week

to two weeks after being bred.

Well you combine those two situations

and you see why having a breeding season

that extends into July and August

is pretty counterproductive.

That explains to me why here in Oklahoma

or across most of the southern plains

we choose to have our breeding season

in May and June and have it pretty well wrapped up

by the first of July.

Or have a fall breeding season that may start

somewhere around Thanksgiving or the first part of December.

And go December into January.

That way we're avoiding this particular time of the year

that seems to be so devastating to conception rates

when we have those really high temperatures day after day

and our nighttime lows never get down enough

for the animal to really cool off

and get back to sub that heat stress situation.

I think you want to keep that in mind

as you're thinking about breeding seasons for your herd.

We wanna avoid this real hot part of the summertime

because it will have an adverse effect

on conception rates year after year.

Hey, we look forward to visiting with you again next week

on SUNUP's Cow-Calf Corner.

Market Monitor

>>> Kim Anderson our crop marketing specialist joins us now.

Kim the July WASDE has been released,

it's been talked about and anticipated.

Give us an idea of what it revealed.

>>> I think it reveals some surprises

but let's start with Oklahoma wheat production.

They increased the yield per acre to 38 from 37 bushels.

They lowered the total production to 104 million down

from 111 so of course they lowered the harvested acres.

Now if you look at the WASDE the wheat production

for all wheat right at expectations 1.92 billion bushels

ending stocks at 1 billion bushels,

that's pretty close to where the market had it.

The hard red winter wheat 875 million bushels,

323 million bushels ending stocks.

Corn production came in at 13.9 billion

I think that's above expectations.

Ending stocks at 2 billion they were expecting down 1.71,

1.78 I think that's gonna hit the market

negative corn prices,

and negative corn prices is negative wheat.

Soybeans came in at 3.845 billion bushels

ending stocks at 795 I think slightly less

than the market expected so that's good for beans.

And cotton 22 million bales,

6.7 million bales ending stocks probably in expectations.

>>> Kind of some good and bad news for the wheat market

sort that out for us.

>>> Well if you start with the bad news I think the first

you gotta look at is the quality.

And it's pretty, that is bad when you're talking about

the quality is bad news.

Test weights less than 60 pounds.

We like it above 60 it's still acceptable

at probably around 58.5 to 59.

But the protein level was coming in

11.3, 11.5.

You know you want that up there around 12.5.

So that's the market just exports you need 12.5

the minimum coming in to Houston

at the export market is 12%.

So that's bad.

You got the fun positions for soft red winter wheat

they're long, 37 thousand contracts.

Hard red winter wheat, they're short 27 thousand.

In other words the market's thinking,

cheap hard red winter wheat.

If you look at the price spread

between soft red winter wheat and hard red winter wheat

it's 64 cents premium soft!

That's gotta be a record spread!

Normally maybe it will be 5 or 10 cents

above hard red winter mostly if you look over past years

hard red's been 15, 20 cents above soft red.

>>> So we have to remember this is a world market

that we're talkin' about.

How does that kind of play into everyone's understanding

and their management approach?

>>> Well I think if you look at the world market

Russian, the Black Sea Wheat,

the early Ukraine, Russian harvest

are comin' in around 13% average protein,

that's too high for bread flour.

(laughs)

That protein will get you strength

and do you want a starchy strength-y rubbery cake

or cookies or anything like that?

The U.S. protein is too low,

the Black Sea is too high it's possible

just possible that some countries

will be buying both Russian wheat and U.S. wheat to blend.

To get that protein level they want.

You look at some good news that's going on in the market.

You know in the Panhandle, that's not necessarily

the world market, but the world market impacts our price.

Wheat's at $4.20, corn's at $4.40

so we're feeding wheat again and I think that's good

for our prices.

I think from a rural standpoint the world's

gonna want this wheat and what protein we have.

However, our domestic millers need this

scarce protein wheat, and I think

they're gonna try to bid it high enough

to keep it in the domestic market.

>>> So we will take that news for sure.

Okay, Kim, thanks a lot we'll see ya next week.

(peppy upbeat music)

 

>>> You know at the end of a long day

or after mowing in the hot sun

sometimes it's really good to reach for a cold one.

You know a brewsky, a barley pop, you know, just a beer.

But you know beer's become a lot more sophisticated,

largely because of the boom in the craft beer industry.

There's been a 14% increase in that industry

from 2012 to 2017.

So what defines a craft beer brewer?

The National Brewers Association defines

a craft brewery as small, independent, and traditional.

By small the association means less than

six million barrels of annual production,

which equates to about three percent

of the US beer market.

These craft beer flavors and styles include

IPAs, lagers, pale ales, amber ales,

seasonal beers and fruit beers.

Plus a broad category other which derive flavor

from ingredients besides the hops like wheat beers,

sorgen beers, and stouts that include flavors

from oatmeal, chocolate, or coffee.

So what is driving this demand for craft beers

over traditional beers whose sales

fell 16% from 2012 to 2017?

Just like the food industry has seen a trend

for exploration of new and less traditional flavors

by consumers so has the beverage industry.

And this demand is largely driven by millennials.

Oklahoma, which recently passed legislation

to allow wine and strong beer sales in grocery stores

this coming October, currently has 42 craft breweries.

But that number is expected to grow significantly

once the new law goes into effect,

which will also simplify regulations

regarding the sale of on premise craft beers

at the microbreweries.

So the next time you want something

cold and refreshing reach for something

a little more sophisticated and flavorful.

Consider supporting the craft beer industry of Oklahoma.

>>> How are you doing John?

>>> Fine, how are you? 

>>> Doing good.

So why don't you tell us a little bit

what you guys got going on today.

>>> Well we got a little growing season fire going on.

>>> You know you wouldn't think of

something this green that would burn this well.

>>> That's right, you know a lot of people

that's their picture of summertime growing season.

Green grass that it just won't burn.

But as you can see right here we got it burning

really well on that.

We've been doing a lot of growing season burning.

>>> So talk a little about the benefits

of burning this time of the year.

>>> Well the benefits of burning this time of year

is pretty much the same kind of benefits

we see burning in the dormant season or anytime of the year.

You can see increased cattle gains,

increase plant palatability, increased,

improved protein on plant species.

Again, wildfire reduction risk and stuff

for removing fuel, so for future wildfires

we don't have those big problems

with things like that going on.

>>> Is it easier to manage this time of year?

>>> It is, as you can see the flames are,

the fire's not moving real fast.

You know we just lit that a little bit ago

and its only traveled about 15 feet.

Whereas if this would have been March or April

it'd already been 100 yards down the way real quick.

Flames are a lot shorter because again that green grass

changes that whole aspect of the way that fire behaves.

Because it's the old growth, it's the old mulch

from previous years that starts the fire,

then it burns and heats up, boils all the water

out of the green grass, and then the green grass

will go ahead and burn within that.

So as you can see it just slows that down

because it takes so much energy out of that fire

to boil all that water out of that.

>>> Yeah, because wildfires are a naturally occurring event.

And this just helps to manage that.

It's good for the land but you wanna just

keep it in control and not get out of control.

>>> That's right.

And that's one of the other great benefits

of this time of year is the safety aspect.

It's a whole lot safer to do,

whole lot easier to maintain and control.

Spot fire reductions, embers blowing out.

Again a lot of times they land in a lot of green stuff

so the risk of spot fires, it's always there,

but it's a whole lot less this time of year.

And then too even if we do have a spot it's real simple.

It's not moving real fast, we can get over there,

put it out not much problem.

>>> And the weather conditions here

are pretty favorable for it, correct?

I mean it's pretty cool out right now.

>>> Yeah, we actually got a really good day today.

Typically it's sunny and it's already hot

and we're dealing with fire out here.

That's one of the bad things.

But today is a nice mild day for summer

in August here in Oklahoma.

So that makes it nice to be able to do that.

That's one of the things you gotta watch out for too,

burning this time of year is just the heat.

The stress and stuff on the crew.

Out here working when it's 100 plus degrees outside

a lot of times and it's even more than that

when you're near the fire.

So we try to make sure everybody rides,

everybody stays hydrated, switch out tasks

so you don't get nobody overheated

and don't get anybody hurt.

>>> And you do have some resources

out there for people who are considering

burning during the summer.

How to pick the right weather conditions,

and what to do right?

>>> Yes we do.

>>> All right, thanks John.
