2017 Year in Review - Tips and Tricks Video

This is another Tips and Tricks video I produced for TurfNet.com with Brian Boll, superintendent of North Oaks Golf Club in Minnesota, which received many views. In this video, Brian explains the Murphy Pump, which is a fabulous liquid transfer pump. This pump is designed and built by Ken Rost of frostserv.com This is something no facility should be without.

2017 Year in Review - Tips and Tricks Video

This Tips and Tricks video I produced for TurfNet.com with Joel Kachmarek, superintendent of Tacoma Country and Golf Club received the most views for the year. Fabulous idea by Joel showing the use of a ski rack to help transport hoses on the golf course quickly and efficiently. View HERE 

TurfNet Video - Area or Zone Management

This ON COURSE video for TurfNetTV received the most attention of 2017. Incredible amount of great feedback I received throughout the year concerning this Zone or Area Management philosophy. Thanks to all for their wonderful compliments. View HERE

My favorite compliment concerning this video. Thanks Paul!

Snow Water Equivilency

I know it's early in the winter season, but let's just say things are off to a very bad start. Snow water equivalency for Vail Mountain is at 21% of normal. I don't think I have seen it this low ever, for this time of year? Fortunately, it's still early and things can change quickly. Take a look at the latest graph.

Vole Test Plots Established

A few weeks ago, I had the opportunity to visit with both the Sonnenalp Club and Red Sky Ranch. The purpose of my visit was to establish some test plots for vole repellency/control using Milorganite organic fertilizer. Thanks to Neil Tretter, Sonnenalp Club and Michael Miner, Red Sky Ranch for being such great hosts and allowing me to perform this testing.

All test plots were 25 square feet and received a rate of one pound of nitrogen per 1000 square feet. Plots were established in areas of consistent vole damage each spring. Most areas were north facing, which will allow prolonged snow cover.

For many years I have noticed vole repellency using Milorganite. These test plots will give me a chance to replicate my past results at other facilities. Can't wait till spring to evaluate. 

Special thanks to Milorganite and WinField United for their support in establishing these test plots.

Here I am, being a mad scientist, weighing material for the test plots. 

This particular test plot at Sonnenalp had already seen some vole activity. 

Many test plots were established next to the native grass to obtain 
the most vole activity.

Explaining to Sonnenalp Club superintendent, Neil Tretter about Milorganite.

Always fun driving to the Red Sky facility to see how they blended the outside 
of their building to the development.

Besides establishing Milorganite plots, Red Sky Ranch Director of GC Maintenance, 
Mike Miner and myself enjoyed a lot of Turf Talk, while on top of the world! 

Many test plots were established on north facing slopes to hold the snow 
cover the longest. This plot at Red Sky was shaded at 1:15pm.

With the course closed, Red Sky was as peaceful as could be. 
Always felt I'm on the top of the world when visiting here.

The Passing of Jerry Coldiron..

Always hard to write something when the news is so sad. A friend of mine and many, Jerry Coldiron passed away during the Thanksgiving Holidays. Jerry was only 60 years old. I'd know Jerry for many years, but really got to know him well over the past five years or so. Jerry was a legend in the golf business and always had that bright smile. He was one of the most caring, thoughtful individuals anyone could know. He was loved by many. Please take time to listen to this powerful podcast by my good friends Dave Wilber and Peter McCormick, entitled Celebrating Jerry Coldiron. You will be missed Jerry! Listen HERE

Sunrises and Sunsets...Colorado Style!

There certainly have been some great sunrises and sunsets over the past couple months. The Colorado high country offers some spectacular photos opportunities of these. Here are a few of my favorite photos of late....enjoy!

Vole Management in Turf

One of the biggest issues for superintendents in the mountain west are those little pesky voles. Voles are rodents and a relative of the mouse. There are over 100 species of voles. The meadow vole is responsible for the bulk of the damage in a turfgrass situation. Voles are herbivores and the majority of their diet consists of grass stems and leaves. In the summertime voles migrate to thick taller grassy areas for protection against predators. However, when snowfall arrives they have protection under the snow and this is the time they migrate to fine turf areas and cause damage. This makes golf course turf very susceptible to wintertime damage. Voles cause turf damage by chewing grass plants extremely low to the ground and can chew so low they cause damage to the crown of the plant. Voles also create runways in the winter, first by chewing the plants, then by using these to forage for additional food each day. These runways can see extensive traffic throughout the winter as voles forage each day on 10-15 trips.

Most of the time voles don’t directly kill the turf plant, although if they damage the crown extensively it is possible. The main issue with vole damage is the slow recovery of the turf in the spring. With the combination of cold soil temperatures and damaged turf plants, recovery can be extremely slow. The other issue with vole damage is its effect on playability. When a golf ball lands in one of the vole tunnels, it can nestle down and make for a very poor lie. So until complete recovery happens playability suffers.

 an application of Milorganite and sand topdressing and is not touched!

Controlling voles is extremely difficult if not impossible. Over the year’s superintendents have tried many different products with minimal success. One product I found which shows some vole repellency is Milorganite fertilizer. I discovered this primarily by accident. I have used Milorganite fertilizer for many years as a dormant feed on greens, tees, and fairways. What I didn’t realize was all those years of apply Milorganite, I was also repelling voles in those areas. 

All the years we applied Milorganite to the fairways we were getting
a side benefit of vole control, which we really discovered in 2014.

This came to light during the winter of 2014-15. That fall we had early snow cover and only finished 11 fairways with our Milorganite application. That spring we had extensive vole damage on fairways that didn’t receive the Milorganite application. We also noticed that spring that late topdressing applications also reduced vole damage. With this in mind, we decided to apply Milorganite to the rough as well in the fall of 2015. We also set-up some small test areas with check plots to test our theory.

Some testing I performed in some grassy hollows which every year suffers
from vole damage. No Milorganite applied on the left and 0.75#N/M applied
to the right. Totally clean from any damage with the Milorganite.

In the spring of 2016 we were amazed at almost the complete lack of vole damage on the property. Our test plots also show without question that Milorganite certainly repels vole activity. We used rate of 0.75#/N/M in all the rough and in our test areas. The results were fantastic. Not only do you repel voles, you also get the benefits of a great dormant fertilizer application HERE: https://oncourseturf.blogspot.com/2017/10/dormant-fertilization.html . Getting two things accomplished with one product, that is a big plus!
