WEATHER UPDATE 47 the Groundsman March 2016 Spring challenge for playability After another relatively benign mild winter for 2015/16, February's grey and wet weather conditions across most of the UK dispelled any hope of an exceptionally early start to spring. Although turf has never completely stopped growing, cold nights have put on the brakes - and created some stressful conditions to manage, at an increasingly busy time for players' demands. Making plans for March is always difficult, given the huge variability in what the weather holds, and its implications for turf. In 2013, for example, March remained bitterly cold with an average temperature of 2.2°C and around 18 nights of frost across the UK (Table above). Compare that to last year, with an average temperature of 5.5°C, and the average daily high of over 10°C in England. Although, for many, it was a false dawn and spring actually arrived late last year. Meteorological records do reveal an overall trend for warmer temperatures in March that, for many, will kick-start some spring turf growth. Over the past decade the UK average for March has been more than 6°C, compared to around 3°C in the 1960's and '70's However, while daytime conditions may look good for turf repair and recovery, remember that the UK still has an average eight nights with an air frost in March, which can frequently be as much as 15 nights in the east of Scotland. The extreme diurnal range of warm days and cold nights create added stress that limits the chance for turf plants to outgrow any damage caused by pests and diseases. Using the GreenCast website to identify the level of disease risk before it hits enables proactive preventative treatments, to optimise product choice and performance. During the difficult spring timing, when there may be cool periods of no growth and warmer flushes, the contact and systemic multi-active components of Instrata covers both conditions for golf course managers. As conditions warm up, the systemic Banner Maxx provides the same protection. Early kick-off with wetting agents Starting wetting agent programmes earlier this spring could aid faster recovery of turf quality, and ensure plants remain healthier through the summer to • Be aware that cold nights can put extra stress on freshly cut turf plants • Use ITM techniques to minimise stress and disease development • Sports turf surfaces affected by Microdochium Patch (Fusarium) over the winter require protection to prevent further breakouts • Watch for local weather and disease risk warnings on the free GreenCast turf management website March Top Tips enhance playability through the year. Even after record wet winter conditions, the prolonged dry spring weather experienced in recent years can seriously affect root growth and plant recovery. Advanced wetting agent technology, combining genuine penetrating and polymer components in Qualibra, provides the opportunity to create firmer, faster playing surfaces earlier in the spring, along with preparing improved growing conditions for turf through the season. l World-leading on-line advice for turf • Up to the minute weather forecasting • Advance warning of turf diseases • Application zone for practical pointers • NEW interactive forums UK March weather records for the past three years reveal the vast extremes in temperature, sun and rain.
