UW Extension Wood County – Cranberries

Rapids Report · Thu Feb 1, 2024

Good afternoon and welcome to Midday magazine for this February 1st, 2024.

Have your host James J. Mailoff behind the mic and we're welcoming on this into the studio.

On the phone lines are good friend Alison, John Jack, regional cranberry educator with UW

Madison Extension Wood County.

Alison, good afternoon.

Good to have you with us.

Good to be here.

I'm always glad to take the opportunity to get to talk with talk with all of your listeners.

We appreciate that Alison and you know talking cranberries and Wisconsin.

That's a mainstay that's something we love to be able to do and to be honest the conversation

isn't always too different from years past but this year in particular we are being hit by

record number highs and we're dealing with some different temps.

Our earth is dealing with some different things.

So we're kind of a couple of questions about the cranberry and cranberry growers right now

that I want to get to with you.

What are cranberry growers doing right now on the marshes?

What's going on with that?

Absolutely, I can give you, first I'll give you what a normal winter looks like and then I'll

give you what your looks like.

Good idea.

So normally we have a, the first time there's a good multi-day cold snap.

Cranberry growers will raise water, they will let a good blanket of ice form.

Ideal is like 12 to 18 inches of ice that will form over like a three day period where we have

below freezing or hopefully even below zero temperatures.

The usual enemy is if we get snow on top of that it can kind of insulate and prevent

a good ice formation but this year I'll continue right.

So usually we get our good 12 to 18 inches of ice.

We then drain the water that hasn't frozen back to our normal water supplies and we have the

plants you know kind of in air their dormant there's ice over the top of them so they have kind

of an igloo and that igloo is going to protect them from future cold temperatures for the rest of

the winter and then also when we have good weather later on in the winter that 12 to 18 inches of

ice is going to support us driving on the beds in order to put out a little quarter inch layer of

sand because our soils are so soft and so compactible we can never drive on them during the growing

season. So this winter winter ice blanket is our only opportunity to get out over those beds

and we like to roughly every four years apply like a quarter inch to a half inch layer of sand.

That sand you can kind of think of it like the equivalent of a grape grower is going to prune his

vines so that he's going to clip off the old woody tissue and that's going to cause new

fresh tissue that's going to produce more fruit to form. So in cranberries you know then in

grapes you have to haul that away and burn it. In cranberries instead we place this layer of sand

the layer of sand kind of buries the older woody tissue and gives the plant a hormonal cue to

send out fresh growth and that fresh growth is going to have more fruit bearing potential and then

also the the older woody stems and the older leaves that get buried then go on to contribute to

soil organic matter and let us use nutrients more effectively and they have microbes that help

the cranberry plant health. So it's a really cool like ongoing process of building up our soils

over time with the organic matter from the plant and then the sand. Okay so that's a normal winter.

This winter this winter we have not had a good opportunity to make ice and some growers were

able to make ice during that cold snap a couple of weeks ago but it's now melting and that is

stressful on the one hand if we were to get a sudden cold snap we might be unprotected the way

we normally be protected with our little ice igloo but more importantly this is making growers

stress out about not being able to do their normal sanding maintenance and if that kind of pushes

pushes normal maintenance back for a year we're going to have we're going to have

you know older tissue where we'd rather have fresher tissue. So we are and that's yeah so that's

the very most basic thing there's also some other questions about well a lot of time with

we rely on the deep freeze of winter to freeze some insect eggs and we rely on the deep freeze of

winter to reduce our disease pressure by killing off some bacteria and so there's a couple of

worries about you know what what what else happens if we don't get that deep freeze that

Wisconsin is so used to yeah so I definitely talked about it so feel free to ask questions back.

So science basically else it no it's it's fascinating I can't thank you enough for breaking

that down for us and giving us the comparison of a normal what a quote unquote normal winter

or whatever that is and into this year's winter but with that being said and and I don't want to say

we we you had no necessarily nobody can necessarily predict exactly how things are going to happen

but in the in the recent years I imagine a cranberry growers have had to adapt quite a bit to

different circumstances. Absolutely as I think farmers are one of the first two

notes that you can account for everything except for the weather is going to bring you

and the weather has definitely brought us some weird things in the past years we had that

summer with a lot of smoke overcast from the wildfires in Uganda somewhat recently and strangely

enough it seemed like our crop turned like ripened up and turned color faster than we were accepting

that year we've had really unusual timing of hail storm usually usually for Wisconsin and we

hate to have hailed no matter what haile has no there's no big thing that comes from haile

but we've had hail really early in the year before the cranberries have set their fruit and so

then we had insurance companies saying boy I know how to calculate how much yield loss you had

if we see berries with bruises or if we see berries knocked off the vines it's really hard to

calculate what hailed image is if it's hitting the bud scales and the buds rather than the fruit

so those are in the last you know I've been backing cranberries for I guess about four years now

and in those four years we've had weird hail we've had the you know those really cloudy you know

wildfire smoke and now we've had this winter so there's been a lot of interesting stuff going on

Allison I I feel like this is a bit of a silly question but I can't help asking

is there any positives to this weather um so yeah actually this um unlike hail which has no

bright side the neat thing about this winter in particular um after one thing that people usually

forget about cranberries since they're a perennial crop they have next year's crop already on

the vine so after harvest those cranberry plants actually continue growing they're still

taking that opportunity when they're not growing you know big delicious fruit they are working on

root production after harvest and usually after harvest we might have like a week or two weeks before

we get into full dormancy of winter and the cranberry is kind of do as much root production as they

can during that window um which doesn't always wind up being very much this year we've had almost

two months after harvest during which those cranberries can can develop roots and really store

store a lot of carbohydrate supplies so even though we don't have the normal protection from

frost you know from cold that we would with our eye with our flood and we don't have our normal

ability to sand um we are hopeful that a lot of marshes we're going to be able to gain a lot of

good root production and give those cranberries some extra energy savings for future stresses

finding these silver linings in life are sometimes difficult but they're important and especially

when it comes to this field and when it comes to agriculture when it comes to farmers there aren't

many people that are more adaptable than this industry so feel comfortable with those things and

feel good about some of the stuff we've talked about today but Allison I'm curious do we have any

I I don't mean for you to look into a crystal ball here or anything but do we have any idea of

what this what this weather might do to this year's crop um that is one that I am not able to say

yeah immediately um I do think that the root development is going to be good um I do think that the

lack of killing trees for a lot of our insect pressure and a lot of our disease pressure might be

bad um so whether which one of those winds is still a matter for speculation and we don't really have

you know one one nice thing about working with generational family farms is there's always someone

who says oh yeah you know 70 years ago when I was 12 this happened um we don't have one of these

winters in living memory uh so we're we don't have a lot of you know even if even if someone

foggy memory over the past is is only a guess we don't really have one of these to look back to

so it's kind of going to be anybody's guess yeah I I'm a big history nerd and I love learning

things and so this part of the reason why I love talking with you but also the guests we had right

before you are friends from this torque point boss they had their weekly they had their monthly um

ice carving and they went out on the ice and they carved it they were a little worried this year

about that and we were we were talking about one of the advantages we have nowadays is so much data

of history and so much weather history and things that we can look back on and all that being said

and and and we still there's still stuff that we don't know about there's still things that we

don't like you'd mentioned there that we don't know we more than likely haven't dealt with a winter

like this before but there isn't really any data that tell us certain that like it's certain we

can only go so far back so I think that's kind of an interesting part of all of this and and how

we adapt how we go forward with it um one of the things that we try to do with these conversations

is certainly inform people but also make sure that we're creating a little bit of empathy and

that our our listeners out there are identifying and and having some empathy for our ag industry and

our growers out there and some of the things that they are going through and we're able to do that

through this process you just broke down for us I appreciate that Alison thank you

very glad to I think there's a lot of I I feel like most people you know have more in common with

farmers than they realize and if you if you find yourself stressing about your lawn or your

you know your your apple trees um similarly you know farmers are going through that same thing and

you know and all the more so we're speaking with Alison John Jack regional cranberry educator with

UW Madison extension uh Alison what outreach has UW done lately um the winter is a because

usually our crops are under ice right now um the winter is historically a pretty big time for

education and outreach so we just last week had our annual cranberry school um and that's a two-day

event where we hear basically from all of the researchers and grad students who have had research kind

of make it from the you know the beginning to the middle phases of research to okay I've got

results to present I've got information that growers can take home to their marshes and so we

just had that event in the delves we had about 350 people attend this year um and I'm just finding

which ways up again after uh after helping organize that um and the growers the Wisconsin State

Growers Association also did a wonderful job helping to helping to orchestrate that and as well they

brought in um associate members for the trade show so there is a lot of good stuff um I guess yeah

feel free to ask me uh how did that go no you some of that yeah we're some of the highlights from it

not I I mean going to the delves in the winter isn't always well I mean it can be a lot of fun but

it sounds like you guys had a great time it was pretty lovely um we had um I think some of the most

popular presentations um we had one of the students of the University of Wisconsin Genesis

Dr. Wanzalapa his student presented uh several uh they have had successful fertile crosses of a

cranberry and a blueberry and Fernando brought in some live plants um showing you know here's

what it looks like if you drop a cranberry and a blueberry and they're working on understanding the

genome and seeing if we can't get some of the natural sugar production from blueberries um while

retaining the cranberry's ability to float so it's a it's a tall task but it was really neat to see

you know physical uh you know we got got to you know touch and look at those plants and that was

cool um it's gonna be interesting to see the data that comes from that yes very much I mean

there there cranberries and blueberries are very close cousins um which is why breeding them in

you know the natural way is possible at all but it still has taken a lot of time to find the right

uh the right parents that that are going to make the kind of fruit that we might be interested in

yeah um they also had um we had some presentations on um the micro-horizal partnerships between

cranberry roots and the uh and the fungi that live in the soil and help make for example

phosphorus available to the plant um I'm trying to think we also had presentations uh from we had

asked the researcher panels uh where growers could live and anonymously ask questions to

our uh plant physiologists and our entomologists and our plant pathologists and our weed scientists

and kind of gets the you know the very nitty-gritty how often should I should I look at um

you know how often should I make this application versus um when when I make a nitrogen

application how long does it take that nitrogen to get up into the plant um and I think those

are always really useful for the growers in terms of being directly you know directly actionable

information such a lot of really uh not only great information but I imagine there was a lot of

great conversations a lot of communicating a lot of uh networking going on as well at something

like this which is always really vital in this field as well absolutely I really admire the

cranberry industry for being so uh you know so close and so interconnected and everyone is

willing to help each other out with like oh yeah I've seen that problem before here's how we

tried it hey definitely don't try what I tried to solve it um but there are definitely a lot of

good good networking opportunities and when we have those researchers present that kind of

starts the discussion of oh yeah I was looking at dissolved oxygen monitoring in my water and here's

what I saw or you know I really which dissolved oxygen meter works best for you which one doesn't

doesn't break when you drop it on the floor on the floor of the cab um all of those kinds of questions

too yeah we've all been there you know we've all done absolutely when it comes to the kind of outreach

that UW is going to be doing what's up next um next week on the sixth we're going to be hosting

the nutrient management planning uh training and that is something that UW does in concert with

that cap um as well as the NRCS and so cranberry growers make nutrient management plans for their

marshes uh discussing you know looking at their soil samples and their tissue samples from the

prior year and determining what are going to be the the most efficient rates of nutrients to apply

um we have our growers go through this training every four years to keep everything up to date and as

we get new information from the researchers make sure that makes it onto the marshes and into

application so we're super grateful for our partnerships with that cap and the natural soil you

know the NRCS the soil conservation service so very grateful for those mm-hmm uh and February you

have something uh pretty interesting coming up as well yeah actually so we just about every month

except during harvest um we have our virtual brown bag series so because there are 18 counties

where cranberries are grown in Wisconsin um one of the things we learned during COVID was that

it's really good to meet it's really good to meet together um but when you've got people driving

fourish hours to get to places you can only do that two or three times a year um we do now that

you know now that we've gotten back in the swing of things we do have our in-person meetings two or

three times a year but we also keep up this kind of drumbeat uh we take one hour these um the lunch

break of third friday's every month and have a little one hour presentation that usually is two to

three uh researchers giving you know timely research updates crop consultants talking about what

they're seeing hatching the fields and frost conditions and plant phase updates and so for February

we're actually going to have um two of the farm management specialists with uh the university

Wisconsin talk about onboarding new hires um and business strategy um so we've got you know kind

of when there's no uh when there's no insects to gossip about we can we can work on um helping

our helping our growers um when they hire new people from the community making sure that they get

a good successful onboarding and have successful you know career paths throughout their their cranberry

life so those are those are exciting as well yeah uh and and just like our ag industry uh there

is never you never taking a pause always finding something to do always finding something to keep busy um

Allison if you don't mind uh in in that uh great information you gave us you mentioned how many

counties produce cranberries how many was that again um 18 counties in Wisconsin 18 we have 72

counties in in Wisconsin and 18 of them produce cranberries that's in that's really cool that is

very interesting yeah just thought that was an interesting note about the conversation and as

we're wrapping up this conversation uh Allison what research topics will be big this year

oh we have had a lot of good questions here so if you might notice over the course of cranberry

history we always care a lot about frost tolerance of lines um because one of the most stressful

periods for cranberry growers is in the spring when the plants are breaking dormancy if you get a

suddenly cold night the cranberries might not be ready for it you have to wake up and turn on

sprinklers and make sure that your your sprinklers protect your cranberry plants from freezing when

they're especially tender um that's been an ongoing research question and we'll continue to be

an ongoing research question especially as we have new varieties but then we don't you know we

don't understand the new varieties as well because we don't have 150 years of history with them

um so kind of speedrunning getting all of that information we can get information a lot faster

thanks to the freezers that we have in the lab and we can put plants through you know induced

freezer stress so we've got a lot of frost frost frost tolerance information but we've also

gotten a lot of questions this year about okay what about heat tolerance information

and so our physiologists are planning they have these kind of little like car hoods that are

going to you know basically be little greenhouses that at our research station and find out what

happens if we give the plants a lot more heat than they were expecting um just because as of this winter

people are concerned about well what happens if it's really warm for some reason um

yeah mother nature is kind of um sorry to cut you up uh mom it just was going to say mother nature

is kind of giving us some of the ideas of hey you guys might want to research with this you might

absolutely absolutely we're a very practical people and this is one of the things i mean i love

research in general i really love agricultural research and applied research because and that's

partly my job but it's so connected to what the growers are immediately facing and it is a

grower says oh man i'm stressed about this a researcher says here's how i can set up a project that

will find out what the best thing for you to do about that is we'll bring in a grad student

we'll do the research make it we'll even do the research on your farm um and we get those

information you know that information out really rapidly so compared to the slower branches of

research that are also super valuable you know cancer research and that kind of thing watching the

watching the tight feedback loop in agricultural research makes me feel really proud of how quickly

we like have a question figure out the answer and help growers implement it yeah it's not something

you come across very often in science when you're able to do that when you're able to get those

kind of results that quickly which is is a really unique and very cool aspect of this field

yes i'm very i'm very glad and i know the growers are very glad as well yeah it helps out especially

with the the times being what they are and as my Nana would say you want to make god laugh make plans

and and that's you know we're we're we're trying to kind of do here is is map out something that is

unmapable and and figure something and the the research and the work that's being done here i don't

know if um if people are understanding how important and how great it is to be able to do this

ahead of the game and get ahead of some of these things possibly get ahead of some of these things

it's it's vital to all of this and and and so interesting it's such a great time talking with you

Allison love talking with you we got to do it more got to come back sooner all right i'm always

i'm always glad to so i look forward to the next time

Allison if people have follow up questions one of the more about some of what we talked about
