Nitrogen & Rain - Should you reapply?

>>> Hello everyone, and welcome to SUNUP.

I'm Lyndall Stout.

The recent rains across Oklahoma

have been helpful in many ways.

But producers who applied nitrogen earlier

in the season may need to reapply.

SUNUP's Dave Deken learns more today

from our Soil Nutrient Management Specialist, Brian Arnall.

>>> I don't think it's a secret

to any Oklahoma wheat producer,

we've had a lotta rain in Oklahoma,

and Brian, what has all that rain meant

for the nutrients in the soil?

>>> So if we look at, you know,

I was just looking at the 60 day

and 90 day total rain falls.

The 60 day, we're looking at lot of teens across the state,

especially the wheat belt, and the 90 day,

we're approaching 20 inches of rainfall

and above that in some areas for the 90 day.

Why that's important is it goes back to

a lot of the wheat that's in the ground now

is graze-out or dual-purpose wheat,

so that means it was planted anywhere

from July on through August and early September.

Which means a majority of its nitrogen

was put down prior to establishment, which puts

fertilization through July, August, and September.

Now fortunate thing is is that our sources of nitrogen

are ammonium-based, so anhydrous ammonia,

it's NH3, goes to NH4.

Unfortunately, ammonium goes through a process

called nitrification, and that happens

in conditions where there is moisture,

and temperatures above 50 degrees.

Problem is, since application, we've had moisture

and we've had temperatures above 50 degrees.

So in just best case scenarios, or best guess estimates,

I would put a few fertilizers in the month of July.

There is a good chance by this point in time,

you've converted as much as 50 or more percent

of that ammonium into the nitrate form,

and if we move that into an August, we're 40 or 50,

again this is rough estimates,

assuming certain soil and weather conditions.

The problem with nitrate is that it is mobile,

and mobile with water.

So these locations, if you look at it,

we have rainfall totaling eight, nine, 10, 20 inches.

That is moving water down through the soil profile,

and when there's nitrate there, it's moving down with it.

So sloping fields, that even if it's on a slope,

you're gonna have nitrate go down,

hit a limiting layer and move down slope.

Deep well-drained fields, so something that drains well,

all that nitrate is going to be draining down to depth.

It may come back later when we have evaporation

bring it back up, but for now, it's effectively lost.

So there is a potential a good amount

of our grazed wheat acres have lost

anywhere between 20 and 50% of the nitrogen

that was applied as preplant.

>>> What should producers do about getting

the nitrogen back in the soil and when should they do it?

>>> So you got a couple scenarios, a couple options.

You can account and just say, you know what, it's been lost.

Let's look at it and let's get

a timeframe, especially grazing wheat.

Let's just get out there when it dries off,

we still have good growth conditions,

and try to get maybe a replacement

for one ton of production.

Something like that.

It's just a guess estimate.

And of course, like I've always supported

is the N-Rich Strip.

If you don't know what's out there,

'cause honestly my guess of 50% loss

is 50% plus or minus 40%.

So you're anywhere from losing 10 to 90%, I don't know.

So go to your county educator, go to your county office,

see if you can borrow a push spreader.

If they don't have one, I'll get 'em one

and put out some strips of nitrogen.

When those show up in the grazed or non-grazed,

we know it's time to fertilize

and we can make those recommendations,

make sure we're as efficient as possible with nitrogen.

>>> With that does it need to be ahead

of a rain or following a rain event?

>>> So, since we're in the fall,

going into cooler conditions,

we have a little bit more flexibility.

When our temperatures are cool, the application

of urea, UAN, what be it, is a little less risky.

If we stay warm this winter,

and we have moisture, it's gonna be best case scenario

to apply in front of a rain, a couple

of days in front of a rain.

Hopefully, get a good 1/2 an inch to incorporate it.

>>> Is it worth doing it now or closer to first hollow stem?

>>> So on a grazing scenario, and again I go back to a lot

of our grain-only is not planted yet.

And so maybe, the nitrogen is not down on it yet.

On a grazing scenario, we hate to lose

forage production due to nitrogen deficiencies.

So I wanna be ahead of that on the forage side,

and that goes back to if we dry out,

we maintain good growth, you look at this field behind us,

we've got great growth out here.

I'd be looking to get nitrogen on,

or at least have a strip out there to know now.

If we're grain-only, if you put on your preplant already

in grain-only, and you've seen anywhere

between six and 12 inches of rainfall

I'm not gonna account there's gonna be a whole lot there

by the time we go to grain, put on your enrich strips,

look at an application anywhere between January and March,

watching the enrich strip, watching that crop progress,

all goes back to, are we gonna be cold this winter, are we

gonna be dry, wet, that changes some of the decisions.

>>> Okay, thank you much, Brian Arnall.

And for more information on that, go to your County

Extension Office, or visit our website, sunup.okstate.edu.

Market Monitor

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

and Kim, another week of what you say

is wheat prices wallowing around.

Everyone wants to know when we'll see an increase.

>>> I think we'll see an increase in U.S. exports

when we see Russia running out of wheat to sell our export.

>>> And when do you think that might be?

>>> Probably January, February time period.

You look at Russia's projected to export about 1.3 billion

bushels, that's compared to a little over 1.5 last year.

They're producing, this year, about 2.5 billion,

little over that, last year was 3.1.

If you look at their exports, that's 336 million bushels

during the August to September time period,

at that pace, they're gonna run out of wheat to export,

they're gonna reach that 1.3 billion by about that

January, February time period, and when they run out,

demand will come to the United States.

>>> And with that in mind, how much do you think

U.S. hard red wheat exports might increase?

>>> Well, right now on the October WASDE,

the USDA's projecting that U.S. hard red wheat,

that's hard red spring and hard red winter wheat,

exports will increased by 71 million bushels.

Look at hard red winter, it's about even with last year,

and you look at hard red spring, about 71 million there.

However, right now, if you look at our current export sales,

hard red winter wheat is 38% below last year's level.

Even exports, that's means we're gonna have massive

export demands when Russia runs out of wheat.

>>> So for producers who might have wheat in storage,

guidance on to sell or to keep storing?

>>> Well there's about a 50 cent risk in the market,

so if they can afford 50 cent risk.

If I had wheat in storage and I could afford the 50 cents,

I think I'd hold out for that January, February time period,

because if the market comes into the United States,

and when it does, we're at five dollars now,

I think we could pick up 75/80 cents if we get good demand.

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

(upbeat music)

 

Cow-Calf Corner

>>> Last week on the Cow Calf Corner, you recall

that we visited with you about how body condition of cows

affects their grade, and therefore their price,

as they're culled and marketed this fall.

If you look at the market news reports,

you'll see that within each grade,

they will have different pricing for low dressing cows,

average dressing cows, or high dressing cows.

What do they mean by dressing?

Well, it's dressing percent 

what they're looking at

is the percentage of the live weight of the cow

that actually will be hung up on the rail as her carcass.

And those cows that are low dressing will generally have

a considerably lower price per pound within each grade.

Some of these low dressing cows may bring 10 to 14 dollars

a hundred weight less than higher dressing cows,

within their particular USDA grade.

What affects dressing percent?

Well the number one factor of course is fill.

Cows that look to be very full.

Perhaps they've been tanked up on water before

they went into the sale ring - those cows will be discounted

as being low dressing percent cows,

because the buyers know that that gut fill

is not going to end up on the rail,

but it's only going to be basically tossed away.

Also, things such as heavy udders, big udders,

will affect dressing percent.

Cows that carry a lot of mud or manure on the hide, again,

those are weight factors that do not show up on the carcass

Those are the keys that probably

will affect dressing percent the most.

I really want to encourage producers

as they cull cows this fall, don't make the mistake

of trying to get them extra full

before they go into the sale ring.

It's counterproductive - those buyers will recognize

that, and discount those cows severely enough

that it'll more than make up for the additional weight

that you might have been able to put on the cow.

So let them go through the ring in normal fill,

and therefore, certainly end up as average to high dressing

cows, and you'll get the better price because of that.

Hey, we look forward to visiting with you

again next week on Sun Up's Cow-Calf Corner.

Getting the most out of your hay

>>> Hay is on the mind of a lot

of producers across Oklahoma now, and Dave,

there's some things that producers

need to be thinking about if they're

wanting to use their hay more efficiently.

>>> Right, we've discovered there're

big differences in hay feeders,

so an experiment we did several years ago,

we covered it before on SUNUP,

we used what I'd call an Ag shop feeder,

just a plain Jane, light, inexpensive feeder

that actually wound up wasting about

21% of the original bale weight.

And the way we counted waste was anything

that wound up outside of the hay feeder

in a 24-hour period where the cows could walk

on it, and so on, and so we could over time

calculate the amount of total hay waste

compared to the original bale weight.

We tested other types of hay feeders,

and one we've got in the background here

has both a basket mechanism and a solid ring

around the bottom to help hold the hay in there.

But this feeder actually wasted about 5%--

>>> [Dave D] Wow.

>>> [Dave L] Of the original bale weight,

so dramatic difference.

And then we discovered that a feeder

that only has a ring around the bottom,

does not some sort of a basket mechanism,

it wasted about, it was about 13%,

and so, yeah, dramatic differences.

>>> So we have the ring feeders,

this one with the basket on top,

what are some other ways of efficiently

feeding hay to cattle?

>>> A lot of people with, we're talking about round bales,

would roll hay out and then just let them clean it up.

The more days of hay you try to feed at one time,

the more waste there's gonna be,

because they'll turn it into bedding,

manure and urine and so on, and stomp on it.

So that waste can be pretty significant

if you're rolling it out,

unless you control the amount they get

and minimize it and make sure they clean it up.

>>> Say a producer takes a round bale,

doesn't roll it out in the middle of a pasture,

doesn't put a ring around it or whatever,

talk about the inefficiencies

that that poses. 

>>> Oh, so that kinda work

was done 25 years ago and it's dramatic waste.

Yeah, because they just,

they immediate begin to tear the sides of the bale down

and they lay on that that's around the outside

and it just gets worse and worse

as you get down to the core of a bale.

Turns out some of those studies

that waste was around 50%.

>>> [Dave D] Wow.

>>> [Dave L] So the cattle didn't consume about half the bale.

>>> When it comes to locations for feeding,

is it better to feed the cattle in a pasture

or in a lot situation like what we have here?

>>> It's a good question,

and one we probably need to work on a little more,

because if you feed in a dry lot like this,

all of the manure, the hay waste,

I mean those are nutrients that can be going

back out into your pasture and distributed,

you can distribute it through your pasture

by moving the hay feeding area.

If you feeding in a dry lot there,

those nutrients are all piling up in the dry lot.

On the other hand, if you set a hay feeder out

in the middle of, say, a native pasture

like the one behind us and just leave it there

for a month and keep feeding hay out,

you're gonna destroy a lot of the plants in that big circle

and so doing some damage there.

So if you're gonna feed out there,

they need to be either rolling out

or frequently moving the bale feeder.

>>> Okay, thank you much Dave Lalman.

Food Whys – What are food defect action level

>>> Occasionally, people will say that

the FDA allows bugs in our food.

It's something they hear on Facebook, Twitter,

somewhere on the Internet,

and it's a little bit more complicated than that.

What these stories are referring

to are food defect action levels

that the FDA has established for different kinds of food.

In other words, these are maximum levels

of natural or unavoidable defects in human foods

that present no health hazards.

Foods that exceed these levels

are subject to action by the FDA.

Something else that's important to remember

is that if a food is actually harmful to a consumer,

the FDA is going to act whether or not

that food exceeds any sort of food defect action level.

It's also important to keep in mind,

these levels aren't for things

that are kind of shocking, insect parts or rodent hair.

But they're also for things like

sticks, stones, stems, soil,

just to name a few other defects.

So that's a little bit of the reasoning behind

why the FDA has set these Food Defect Action Levels.

It's also important to remember

that many food companies have their own quality standards

that are much more strict,

and if you're still grossed out,

something important to remember is that

before there was ever an FDA,

people were still eating food,

and everything that came along with it.

Managing weeds in fall

>>> We're joined now by Misha Manuchehri,

our Extension Weeds Specialist.

Mischa, with winter crops, come winter weeds,

and with all the rain,

we're kinda wondering what you're hearing

from producers around the state,

and what you're also seeing.

>>> Yeah. So seems like producers are already planted,

and they probably have some winter annuals coming up,

even hearing about some summer annuals coming up.

I've received many phone calls on pigweed,

palmer amaranth emerging, and wheat.

Typically this is a time period

where it's too late for them.

But they are up, and I'm getting some questions on that.

>>> Do you think it's because of all the rain?

They're just getting a little, a little extra something.

>>> Yeah. Rain, moisture for sure,

and then up until we had this cold period,

we were still relatively warm.

Soil conditions were warm,

so we had some layered germination,

and we're dealing with that now.

>>> Let's kinda start with the folks who haven't planted yet

in getting their fields ready and optimal

for getting crops started.

What kind of guidance do you have for them

at this stage?

>>> So one of the best management practices we can do

as far as weeds go is start clean.

Once we have that crop in there,

we have to think about not killing that crop

when we're applying herbicides.

So if we can start clean,

whether that is with herbicides or tillage,

giving that crop the competitive advantage

before we plant is great.

I know we're all getting anxious to get our seed in there.

I am as well.

But really making sure that our crop has an opportunity.

>>> And then in terms of those

who have had wheat sprouting up

in the last month or so,

what kind of guidance for them?

>>> So if we have weeds emerged,

whether they're broadleaves or grasses,

we do have some early herbicides that we can go out with,

just pay attention to that label,

and the timing.

Some of our post-emergence products,

we need a couple leaves on our wheat.

If we're going out with a pre-emergence herbicide,

we do need activation of rain.

Those pre-emergence herbicides sit on the soil surface.

Our weed seeds are beneath the soil surface,

and so they need to be washed into the soil profile.

>>> And it sounds like you and your colleagues

are going to talk about some of these topics

and a lot more at an upcoming event.

>>> Yes. So Friday, October 26th.

The official start time is 9 a.m.

but we'll have coffee and doughnuts at 8:30,

and we will be talking about weed management practices

that you can use in small grains,

and we'll be highlighting when are wheat, barley,

and also canola.

It is at the Stillwater Agronomy Farm.

It is open and free to the public.

If people can RSVP that helps.

We get enough refreshments but anyone can come,

and it will probably last until 11, 11:30.

It will be most of the morning.

>>> And people have really have enjoyed it in the past.

>>> I think so, yeah.

We usually at least learn something.

>>> Of course.

Okay.

Well thanks a lot Misha.

Mesonet Weather

>>> Hello.

Wes Lee here again with your weekly Mesonet weather report.

Freezing temperatures arrived as expected in the state

this past Sunday.

It was almost on par for the first average freeze date

in far North-Western Oklahoma

according to the National Weather Service in Normand.

They indicated that the first average freeze

would be between the 15th and the 22nd of October

for this location.

The front lingered with us for three days

providing a hard freeze to 18 counties

from Erick to Foraker and West

throughout the panhandle.

Not only was it the first significant

autumn cold front of the year,

it was one for the record books.

While the daily lows were not

that much out of the ordinary,

the coolest recorded high temperatures

were record shattering.

On Monday October the 15th the highs for the day

were the lowest ever recorded on that day over

a majority of the State since we've begin keeping records.

Only the panhandle and far south eastern Oklahoma

did not see record breaking low daily high temperatures.

On the 16th, the front had moved further

to the south east again breaking records for the

lowest recorded high temperatures for the day

in the southern tear of counties.

While the weather may remain cooler than normal for a while

there are no significant freeze events

in the short-term forecast.

Next up is Gary's summary of the state's moisture situation.

>>> Thanks Wes, and good morning everyone.

Well we did our darndest after all that rain

over the last few months, we tried to get the entire

state out of drought, we almost made it.

There's just one stubborn area up in north east Oklahoma.

Let's get right to the new drought monitor map

and see what we have.

Well if you look at most the state we have

just a couple of areas, small areas,

of abnormally dry conditions out across the very very tip

of the western panhandle down in Forest, southwest Oklahoma.

That's nothing to worry about.

Those are areas coming out of drought.

The problem area, though, remains centered on Osage County

over into Rogers, Washington County, that area

but by and large across the entire state,

drought is not a problem unless you're in that

problem area in the northeast.

And what's really odd is if you look at the

Departure from Normal Rainfall map from the Mesonet map

for the last 90 days, most areas of the state

are at least a couple of inches above normal.

Areas down in south central Oklahoma

are from 10 to maybe even 20 inches above normal.

But by and large, again, very good range

across the entire state.

Now as we look towards next week,

we might have a little bit more of the same.

We see increased odds of below-normal temperatures

at least for October 24th through the 30th

but then increased odds of above-normal precipitation,

again, for that same period.

Next week we might have some of the similar conditions

of what we've seen recently.

The key, though, to that next week is to get that up

into northeast Oklahoma where it's actually needed.

That's it for this time.

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

Vet Scripts

>>> If I mention the word Rabies

I think most people would have an image in their mind

of this very aggressive dog with large amounts of drool

coming from its mouth, snarling teeth,

and attacking everything in site, which is not

a bad image if we think of the purest form of Rabies.

In the world, approximately 50,000 to 60,000

people die every year from Rabies infections.

In the United States, we have very few people die

and the sad thing about that is most of them

never realize they've been exposed to the virus.

In order to be infected with Rabies,

you have to be in contact with an animal that

has the disease and we get it from the saliva of that animal

So most people would be bitten by then, but,

you could just come in contact with the saliva

and have a cut in your skin and then the virus gains entry

to the body that way.

There are basically two forms of the disease.

As we mentioned earlier, the Furious form,

in which we have very aggressive animals,

animals that will attack anything

but the other form of the disease,

what we refer to as the Dumb form or Paralytic form

of the disease and this particular form

of the disease is not uncommon in our farm animals

such as cattle or sheep or goats or horses.

In this form of the disease a lot of times

will mimic a digestive problem in the animal.

Cattle may have a little bit of bloat,

they may drool a little bit.

A lot of time people will think that the animal

has something caught in its throat

and then the next thing we know we've got the mouth open,

we're examining this mouth, maybe running our hand

down their throat, try to find that object

when all along the animal has Rabies

and we're being exposed to that virus.

The other thing is a lot of them will appear to be

constipated, having problems defecating or urinating.

Any time you have an animal that is acting a little bit off

maybe a little bit in a stupor, you think

this animal acts like its a little bit dumb,

be fearful that the animal could have Rabies

and you need to get your veterinarian involved.

There is no treatment for Rabies.

It's usually always fatal but I would like to suggest

that if you have show animals or horses,

these would be very good candidates

to vaccinate for rabies also.

If you'd like more information about Rabies,

if you would go to SUNUP@okstate.edu.

We'll put some information there at the side.

 

Land tenure survey deadline approaching

>>> Finally, today the surveys in the mail.

Producers and landowners around Oklahoma

are receiving a survey asking about land rental rates.

Today, Roger Sahs explains why your input is so important

and how this information will be used.

>>> It's a joint effort with the Oklahoma field office

with NASS and also with OSU

and we're sending it out to about 5,000

potential respondents state-wide

and we are hoping that they will respond to those

with some viable data so that we can compile

that information and report that in

two Extension reports.

We're hoping to get the going market to rental grades

here in Oklahoma with the pasture and crop land

as well as some of the typical, I would say

terms or arrangements with, say, crop shares

or with some of the other rental arrangements

with the tenure rental rate here in the state.

We can pass that information along to

potential tenants and landlords.

They can set up some equitable and fair leases with those.

It gives them a starting point.

It gives them some guidance as to

what the going rental rate is.

It doesn't necessarily mean that that particular

rental rate does apply to their own situation

but it gives them a starting point.

It gives them a basis of negotiating what that

fair and equitable rental rate might be.

It really only takes a few minutes of their time.

And we really encourage them to, you know,

sit down and spend a few of their precious minutes

with this information because we really feel that

information will benefit their operations.

 

>>> That'll do it for us this week.

Remember you can find us any time SUNUP.okstate.edu

and also find us on YouTube and social media.

I'm Lindell Stout have a great week everyone

and remember Oklahoma agriculture starts as SUNUP.
