ICL Offer – Ryder to go in the tank with your fungicide

ICL are currently doing a great offer on Ryder to go in the tank with our fungicide applications that’s well worth taking a look at. On the back of this leaflet you’ll see some data from a trial we did at the Irish Sports Turf Institute in 2018. In this trial we did some work…

Finland Light

I was fortunate enough last week to be invited out to Helsinki in Finland to talk to a group of course managers. It was brilliant to go and visit a different area with some different challenges. They’ve been having a very different year to normal with very mild temperatures and more rainfall (sound familiar?). Helsinki…

Photosynthesis, Light Units and Turf Growth

Light is a key component of Photosynthesis – put simply no light, no photosynthesis. During the winter months with shorter days, even though we have temperatures suitable for growth, it’s very likely we’ll go through periods when light is the limiting factor. I’ve grabbed a few slides from a recent presentation myself and Dr Andy…

Light – The limiting factor?

Got an email today from a Course Manager asking: “Greens don’t appear to be as healthy as they have in previous years at this time do I think that light levels would have any impact on this?” It’s a great question and ties in nicely with some of the work we did at STRI last…

Etiolated Growth – Why, Just Why?

It’s that time of year when we all step back and search for the reason for the Etiolated growth that is appearing on many venues across the UK over the last two weeks. This soft, pale elongated growth can appear quickly and detracts from the visual impact of the surfaces you’re presenting. There has been…

Light intensity, sunshine and day length – the numbers

To follow on from my last blog on light intensity you can see an interesting picture forming below. The below pictures show varying degrees of sunshine, intensity and day lengths. All the figures are for Sandwich Down on the south east coast where I usually find the highest sun intensity figures. All the map images…

Light levels 2018 vs 2019 – Turf Management

Below are two graphs show light levels for all of 2018 and light levels so far in 2019. If you’ve read my last two blogs you’ll have a pretty good idea what’s going on and you can skip to the next section – if not here goes the simple version: The green lines are good,…

I’ve seen the light – Impact on Turf

As we are now in the period of the longest days of the year it’s worth revisiting light and how it impacts the plant. Photosynthetically useful light is measured in Micromoles per square meter per second (µmoles/m2/s). This is a unit of the intensity of the light and can range in the UK from 0…
