“We’ve Made Great Strides in Becoming One”DAVID NOZAL

MPSTMA President

Wow the year has flown by! I wanted to say thank you to the board and thecommittee members who help make this organization work. Your sound coun-sel, creative ideas, and service are greatly appreciated. The MPSTMA has madegreat strides in becoming one organization after our recent merger a few yearsago.

We’ve worked hard to step up the quality of our programming and our orga-nizational operations and it shows. Our education programming has been wellattended and the networking picnics have been fun and informative as usual.The newsletter continues to grow and is looking better than ever.

I’d also like to thank our commercial members whose industry expertise andfinancial support help our organization. Your sponsorship of our educationevents, network picnics, and newsletter advertising is greatly appreciated. Yourknowledge and the ability to educate us about the next great thing are also wel-comed as we all try to do our jobs more efficiently.

So to wrap this year up, thank you to all our members and those who’veattended our education and networking programs. Your continued support,feedback, and service are what make this organization grow and thrive. I’dencourage anyone who’s remotely interested to step forward and take a moreactive role either on the board or served on one of our committees. You will findit to be fun, educational, and a chance to expand your professional horizons.

As I step down as President, you will be left in the capable hands of RickBeane, St. Louis Park – Parks. Rick has been a previous board member and hasgraciously answered the call when our previous Vice President resigned unex-pectedly this fall. Rick will bring a blend of Parks and Sports Turf knowledge tothe organization. I’d like to welcome Rick as our President for 2013!

Keeping It ClearBy KEN ROST

Frost Services

It’s inevitable! Winter, that is. Regardless of whether or notyou look forward to this time of year, this is when instincts andtraditions take over our lives. We feel the urge to drain, wrap,cover and close up anything that needs it to survive the next fewmonths. We assess the condition of our snow equipment and thepile of ice melt salt bags we have left over from last year. If we’relucky, they haven’t gone solid like field stones.

Traditions are great for family get-togethers and meals thathelp feed the bear inside us. But the practice of spreading salt forice melt might be a tradition that needs to be pondered. We allwant to keep our traffic areas safe to minimize accidents and fallsand salt has been a traditional tool to help minimize the labor.But when it seems like salt isn’t getting the job done, our tenden-cy is to add more. More is good, right?

What if there is a better way? This question has sparked inno-vation and new methods have been developed in the business ofkeeping our traffic areas clear of snow and ice. These new prod-ucts and methods will likely become new traditions very soon.

When we have just one option, a decision is easy. That’s tradi-tion. When we have many options, the decisions about what icemelt to use get complicated. In this article, we will summarizecommon ice melt options available today and the methods forusing them that might deviate from tradition.

Keep in mind that the process of melting snow and ice is anexercise in physics and chemistry. In a laboratory we can controlvariables and determine a temperature when a product ceases tomelt ice. This is how phase change melting points are deter-mined. However, in real world applications, many variables willalter the laboratory determined temperature. Moisture level, sun-light, air temp and surface temp are the main variables that affectmelting temps. If we include these variables in our evaluation,we come up with an effective temperature. Effective temperatureis simply a relative temperature determined through practicaluse of the product. We’ll use effective temperature to compareice melt materials.

Dry Salt (NaCl) – Effective Temperature = 150F

Traditional salt is relatively inexpensive but it has a limitedeffective temperature. It is very corrosive and even within thecategory of ‘salt’ there are differences. Mined salt is taken fromdeposits left years ago during the formation of earth. It often con-tains other minerals and possibly inert materials that don’t helpmelt snow and ice. Solar salt is harvested from lake beds andother areas where salt water has been evaporated. Solar salttends to be more pure NaCl and is more consistent in its effectivemelting temperature. Here’s a chemistry reminder, dry salt does-n’t melt anything. Only when salt goes into solution does it startto melt surrounding snow or ice. In order to get the process start-ed, many salt products are ‘pre-wetted’ with a de-icing liquid.This method will speed up the melting process by about 20 min-utes and usually lowers the effective temperature by 5-100F.Automatic pre-wetting systems are common on DOT trucks thatapply dry salt.

Dry Calcium Chloride (CaCl2) – Effective temperature = -150F

The effective temperature of dry calcium chloride is muchlower than traditional salt which makes it a better choice for thecolder periods of winter.

Dry Calcium Chloride (CaCl2) – Effective temperature = -150F

The effective temperature of dry calcium chloride is muchlower than traditional salt which makes it a better choice for thecolder periods of winter. The cost of calcium chloride is higherthan salt but theoretically lower amounts can be used. Being adry product, the rules about being effectiveness when dissolvedin a liquid state apply to calcium chloride also.

Liquid Calcium Chloride (CaCl2) - Effective temp = -200FLiquid Magnesium Chloride (MgCl2) – Effective temp = -100F

Liquid chlorides are the most common liquids that are used topre-wet salt as described above. They are also emerging as effec-tive liquid products that can be directly applied to surfaces. Theycan both prevent snow and ice adhesion to pavement, and meltexisting snow and ice. Liquid chlorides are corrosive and moreexpensive than salt on a volume basis, but their effective temper-atures are substantially lower than salt. This means that smallamounts of liquid chloride products can be used to achieve goodresults. Liquid chlorides are hygroscopic which means that they‘collect’ moisture. Their molecules seek out water and bind withH2O molecules. The result is a liquid solution on the surface witha much lower freezing point. The benefit is that snow or icewon’t adhere to pavement. It creates a non-stick surface muchlike a coated frying pan.

(Continued on Page 4)


Keep It Clear -

(Continued from Page 3)

This is where a change in method comes in. Instead of plowingand spreading dry salt afterward to melt remaining snow, liquidchlorides can be applied before the snow fall. After plowing, theliquid chloride remains in the pavement and an application ofsalt will usually be unnecessary.

Let’s use two sidewalks as a theoretical example of how liquidchlorides work. We’ll apply the liquid to one of the sidewalksabout 6-8 hours before a 6” snowfall. The first thing we’ll noticeis that there is 6” of snow on the untreated sidewalk and 5” onthe treated sidewalk. The liquid chlorides will initially consumeabout 1” of the snowfall. Then let’s have heavy traffic on bothsidewalks for a couple of hours. After the traffic we’ll get aroundto plowing. The untreated sidewalk will be difficult to clear andwill undoubtedly have snow and ice bonded to the surface. Thetreated sidewalk will clear off easily and any remaining snowwill be dissolved by residual chloride. If we spread dry salt onthe untreated sidewalk, we may not get it cleared off for daysdepending on sunlight, air temp, etc. Pre-applying the liquidchloride bought us time so that we didn’t need to plow immedi-ately after the snowfall or before the traffic to prevent adhesionto the pavement.

Acetates (KAc) –Effective Temperature = -200F

Acetates are a non-chloride type of liquid that have low effec-tive temperatures and are non-corrosive. They are approved by

the FAA for airport runway de-icing and are commonly used onautomated bridge de-icing systems. The cost of acetate liquids issubstantially higher than chloride liquids because they cost moreto produce. The methods for using acetates are the same as forliquid chlorides.

Agricultural By-Products

We often hear about agricultural by-products being used forde-icing and they are a popular topic because there is very littlecost for the materials. Examples are by-products of sugar beetprocessing and whey from cheese making. They don’t have sig-nificant effective temperature benefits on their own and ifapplied directly they can have undesirable traits such as slipperi-ness or smell. They do provide some benefit to blends. Forinstance, adding sugar beet molasses in a salt brine blend canreduce the corrosive activity of the salt substantially.

Blends

Blends are a good way to balance the effective temperature ofan ice melt product and cost. DOT’s, counties and municipalitieswill often create liquid salt brines and add liquid chlorides tocustomize a liquid for their area. Dry and liquid chloride blendsare usually created by wholesalers and are sold under brandnames. Blends can complicate the buying decision. Blends oftenhave lower effective temperatures than their individual mainingredients due to chemical interactions within the blend. But ifyou pay attention to the main ingredients and knowing theireffective temperatures you can usually make a reasonable choice.

Sand

Sand is a traditional tool and it is useful when temperaturesare below the effective temperature of all the fore mentionedproducts. It is good for temporary traction on the surface of iceonly. Sand needs to have some salt mixed in with it to prevent itfrom freezing solid. Before using sand, consider the fact thatsomeone will need to clean it up in the spring and sand is veryhard on interior floors when tracked into buildings.

One more thing to consider when choosing an ice melt prod-uct is the impact on the surrounding environment. The MPCAhas reported an increase in salinity levels of roadside soils andwatershed areas around roads treated with salt during the win-ter. MNDOT aims to address this by adding liquid blends andpre-treatments to its strategy for minimizing dry salt use. A lot ofdry salt gets bladed off directly onto surrounding turf. Liquid de-icing products don’t get bladed off. Increased soil salinity canalso be an issue for turf and ornamental areas adjacent to side-walks and parking lots. It is often necessary to replace soils withhigh salinity before resuming turf growth. Knowing this, the‘more is good’ argument doesn’t seem so smart.

There comes a time when old traditions get broken and newones are started. The best way for a new tradition to succeed isfor there to be a cost benefit. Alternative de-icing products andmethods described in this article have been proven to savemoney. The MPCA published a Winter Parking Lot andSidewalk Maintenance Manual which includes some case studieswhere municipalities, schools and businesses utilized alternativesand saved money. The MPCA is also a good resource and refer-ence for more information on this topic. Lastly, your associationhas affiliates that sell both the materials and the equipment toapply alternative de-icing products. Affiliates are a valuableresource for quality products as well as expert advice. Utilizethem and enjoy winter!

The U-1 (stadium field) at theNational Sports Center in Blaine, MN,is the 2012 recipient of the MPSTMA/ TURFCO Field of the Year award.The NCS sports fields are cared for bySuperintendent Curtiss Conkright,and Assistant Superintendent BenWallin. “We are proud of their fieldbecause of the “hard work and effort weput into it,” said Wallin.

The stadium field, U1 as it is named, isjust one of 50 soccer fields. “We take greatpride in this field but, we can not devoteall of our attention to one field. On a gamenight it is always ready to go. It is cutshort, lines painted, goals in place and itlooks great!” said Wallin.

In July 2012, more than 17,000 peopleattended a concert for KTIS radio.

The National Sports Center annuallyhosts the USA Cup, the largest interna-tional youth soccer tournament inAmerica. This is a week long event andthe stadium will have about 60 gamesplayed.

“We have a concert on the field and anopening ceremony, a lot like theOlympics,” said Wallin.

“We have high expectations for ourfield and we try to fulfill all of them withthe best conditions possible,” addedConkright.

Once again, we have a very deserving winner for our annual MPST-MA/TURFCO Field of the Year. Curtissand Ben have the Stadium Field in great

shape this summer, especially with theamount of play it gets throughout thesummer,” said Greg Brodd, TurfcoManufacturing. Brodd will present theaward on behalf of Turfco Mfg. at theMPSTMA Annual Meeting on Thursday,Jan. 10, 2013 at the MinneapolisConvention Center.

MPCA recommends a low-salt diet for Minnesota waters.Doctors tell us to stick to a low-salt diet. Our lakes and streamsshould follow the same advice. When winter comes and snowand ice build up on Minnesota roads, parking lots, and side-walks, one of the most common reactions is to apply salt, whichcontains chloride, a water pollutant.

Salt Pollutes

When snow and ice melts, the salt goes with it, washing intoour lakes, streams, wetlands, and groundwater. It takes only 1teaspoon of road salt to permanently pollute 5 gallons of water.Once in the water, there is no way to remove the chloride, and athigh concentrations, chloride can harm fish and plant life. Less ismore when it comes to applying road salt.

Follow These Simple Tips To Protect Our Water!

There are many ways to reduce salt use while maintaininghigh safety standards.

Shovel

The more snow and ice you remove manually, the less saltyou will have to use and the more effective it can be. Whetheryou use a shovel, snow blower, snow plow, or ice scraper, getout there as early as you can and keep up with the storm. Youmay decide that salt isn't needed.

15°F is Too Cold For Salt

Most salts stop working at this temperature. Use sand insteadfor traction, but remember that sand does not melt ice.

Slow Down

Drive for the conditions and make sure to give plow driversplenty of space to do their work.

Be Patient

Just because you don't see salt on the road doesn't mean ithasn't been applied. These products take time to work.

More Salt Does Not Mean More Melting

Use less than four pounds of salt per 1,000 square feet (anaverage parking space is about 150 square feet). One pound ofsalt is approximately a heaping 12-ounce coffee mug. Considerpurchasing a hand-held spreader to help you apply a consistentamount.

Sweep Up Extra

If salt or sand is visible on dry pavement it is no longer doingany work and will be washed away. Use this salt or sand some-where else or throw it away.

Know About the Salt Product

Salts can range from simple table salt to calcium chloride.Salts are used because they are able to decrease the freezingpoint of water. Whatever product you chose, make sure youknow at what temperature it stops working. (See Table 1)

Late Fall Tree TipsCourtesy of S&S Tree Specialists

Give Trees Some Space, Air Space

Roots grow within airspace in soil. After years of lawn mow-ing your yard, trees have had their soil compacted. You can use agarden tine spade to loosen the soil softly by inserting it 5-6 inch-es into the soil and lifting or rocking the spade forward. This cre-ates air pockets and holes whichallow moisture in and let’s freezingand thawing loosen the soil. Thiswill greatly help root development.Commercial tree and landscapecompanies also offer this service.

Trim

Deadwood (larger dead limbs) greatly reduces your treesenergy reserves. Now is the time when you can do a quick andeasy assessment of your trees by simply walking under them andlooking at the amount of dead wood in the crowns. If you seelarge branches over 2-3 inches, the tree will benefit from a prun-ing. By giving them a winter deadwood trim you reduce hazardsand greatly increase the energy the tree has to heal itself.

Keep Them Warm

A three inch blanket of wood chips extending out 10 feet fromthe base of the tree will provide a stable environment for yourtrees root system. It maintains moisture levels and reduces dry-ing of the topsoil and it also greatly mitigates temperature

extremes which often cause damageto the root system. By providing thislayer of insulation you will improvethe health and vigor of your valu-able trees.

Review the Year

If your tree had a specific insector disease problem in 2012, chances are it will be back in 2013.Prevention is the key to a majority of tree issues. Contact a rep-utable tree care company now to set up 2013 treatment. Beingproactive will ensure that your trees are taken care of when thetime is right, not when you notice damage.

If you can just do a few of these treatments on your trees theywill grow stronger, last longer and provide you with years ofpayback in shade, wildlife habitat and visual beauty.
