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… Read More Photosynthesis, Light Units and Turf Growth
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… Read More Light – The limiting factor?
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… Read More Light intensity, sunshine and day length – the numbers
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,… Read More Light levels 2018 vs 2019 – Turf Management
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… Read More I’ve seen the light – Impact on Turf
Loading… March was dry, temperatures fairly good and last weeks Twitter feed was full of stunning looking golf courses. It’s at this time of the year things begin to start moving, all the winter projects feel like they were worth it and the compliments begin rolling in. For a long time, we’ve associated this change… Read More March light – Turf Growth
Whilst scrolling through Twitter on this unseasonably sunny February day I came across this Tweet from @British_wx showing the sunshine hours for the 25th February. The dramatic difference in sunshine hours across the country got me thinking about the extremes of light and the role it has in photosynthesis. Winchester 19 DLI Inverness 9 DLI… Read More Winchester to Inverness – extreme light differences and the impact on Turf
