Welcome – education and focus on sustainability

Maria Strandberg and Bruno Hedlund, STERF

Sustainable turfgrass management – a Nordic and international research and industrial perspective

Maria StrandbergMaria Strandberg is Director of Scandinavian Turfgrass and Environment Research Foundation, STERF. Maria has more than ten years of experience in working with golf and environment and she is actively involved in scientific issues regarding all aspects of high quality, and environmental and economic sustainability of golf facilities. Maria serves on the boards of important international golf and research organisations: Golf Environmental Organisation (GEO) Technical Commission; The International Turfgrass Society board and she is the vice president of the European Turfgrass Society. In 2008 Maria received an award from the King of Sweden for her national and international work on integrating golf and environment and in 2011 she received GEO Environmental Award for her significant contribution to sustainable golf.

Bruno Hedlund Bruno Hedlund is the Chairman of the Scandinavian Turfgrass and Environment Research Foundation, STERF. Bruno has worked for more than fifteen years with sustainable golf development and strategic development of the golf sport, as board member in different golf organizations. Professionally, Bruno Hedlund has been President for different industrial research companies and institutes and is also a member of several international scientific boards and committees.

Today mankind is not operating the earth in a sustainable manner, we daily face problems that needs a global approach to be solved. Loss of biodiversity, nutrient leakage, chemical hazards, global warming and climate change are global problems that relates back the turfgrass sector. Managed turfgrass areas when designed and managed correctly all can provide an important social, environmental and economic resource.  Based on this, it is apparent that the turfgrass industry faces a number of local and international challenges, all of which will need concerted and collective solutions, underpinned by robust, applied science.

Stefan Nielson, Course manager at Vallda golf course, Sweden

Maintaining a sustainable golf course

Stefan NielsonStefan Nilsson has been working in practical greenkeeping for twenty-four years, the last twenty as a course manager. For the past eight years, Stefan has been employed by Vallda Golf & Country Club in Gothenburg where he led course construction and ongoing maintenance.

The course was seeded to red fescue that provides enhanced sustainability and unique playing conditions.

The presentation
Stefan will talk about his experiences regarding low input management and practical greenkeeping.

Agnar Kvalbein, Bioforsk, Norway
Optimal plant nutrition from the green grass’ point of view

Agnar KvalbeinAgnar Kvalbein worked as lecturer for Norwegian greenkeepers at Gjennestad Horticulture College until he became a part of Bioforsk Turfgrass Research Group in 2007. During his first years in Bioforsk, he conducted research together with Dr Tom Ericsson from the Swedish Agricultural University on optimal fertilizer rates for grass species under golf green conditions. Kvalbein is now leading a research project where the goal is to find optimal autumn fertilization rates for creeping bent grass and annual meadow grass.

The presentation

Every plant species has genetically a maximum growth rate, but the actual growth is controlled by temperature, light and access to basic elements like water and carbon dioxide. To produce healthy turf the fertilizer rates should be adapted to both the genetics of the plant and these environmental factors. The presentation aims to explain some important relations between nutrients and plant growth and also to bring a few highlights from the ongoing autumn fertilization project.

Thomas Pihl, Course manager, Furesø golf course, Denmark

Fertilization in practise

Thomas PihlThomas Pihl is a certified gartner and greenkeeper, working as the course manager at Furesø Golf club.

"Knowledge and innovation is what inspirers me most, working on a golf course with many restrictions."

The presentation

How do you fertilize the golf course in practice, when you need to take matches, playing quality, diseases pressure and restrictions etc. in to consideration?

Practical hands on experiences from Furesø Golf club/course.  


Jerry Knox, Cranfield University, UK

Engineering better irrigation in turf – research progress and management challenges

Trygve Aamlid, Bioforsk, Norway

Results from Scandinavian projects on deficit irrigation

Trygve AamlidDr. Trygve S. Aamlid has a background in plant physiology / crop science / seed production from the Norwegian University of Life Science and has since 2003 been the leader for turfgrass research group in NIBIO – The Norwegian Institute of Bioeconomy Research (formerly Bioforsk). He is a board member of the International Turfgrass Society and the European Turfgrass Society and vice chairman for the Scandinviian Turfgrass and Environment Research Foundation (STERF).

Dr. Yajun Chen (51) of the Northeastern Agricultural  University in Harbin, China, is currently a vistiting scientist  at the NIBIO Turfgrass  Reseach Centre, Landvik, Norway. One of her main interests is turfgrass drought physiology.

The presentation

In their  talk at the ETS field day, Drs. Aamlid and Chen will present results on deficit irrigation results from the two STERF projects, ‘Evaporative demands and deficit irrigation of golf greens’ and ‘Best management practices of red fescue golf greens  for increased playability and sustainability’.  A central topic in the presentation will be the effect of irrigation regimes on competition with Poa annua.  

Asbjørn Nyholt, Denmark

Quality on sports fields without the use of pesticides – how is this possible

Asbjørn NyholtTurfgrass agronomist and owner of Asbjørn Nyholt ApS since 2008, with 20 years in the turfgrass industry.

The core activity is specialized knowledge of the potential inherent in turfgrass, maintenance and growth requirements. A strong national environment reinforces the development of the industry. A core value of our company.

Quality on sports fields without the use of pesticides – how is this possible.

Since 2013, the Danish league focused on the development of the maintenance of natural grass in the best and second-best league in Denmark. The driving force has been testing playing quality, herbage and construction. The test system (ProPitchSystem) was developed by Proleisure, UK. The development  was anchored within the existing framework in terms of economy and environment.

Thomas Randrup, The Swedish Agricultural University (SLU), Alnap, Sweden

Maintenance quality descriptions of grass in the Nordic countries – do they contribute to the overall sustainable management?

Thomas RandrupThomas Randrup is Landscape Architect and PhD, working as researcher and research coordinator at the Swedish University of Agricultural Sciences since 2015. Previously, he has been professor in Green Space Planning and Management at University of Copenhagen, Business Unit Director at NIRAS Consultants, and Business Developer at HedeDanmark, the largest landscaping company in Northern Europe. Thomas specializes in urban green space management, combining planning and maintenance, and has special focus on quality aspects of urban green spaces. 


Maintenance quality descriptions of grass in the Nordic countries – do they contribute to the overall sustainable management? Thomas will present the principle behind the standard quality definition related to green space maintenance, and he will argue that these operational standards focus on resources and actions, more than on results and effects. New ideas to an overall sustainable approach is discussed.
