Integrated Turf Management (ITM) is a strategic approach to turf care that is increasingly recognized for its efficacy and sustainability in the golf, sports, and landscaping industries. ITM involves the integration of various cultural, biological, and chemical practices to maintain healthy and high-quality turf.
One of the core principles of ITM is the integration of soil and water management techniques, advanced pest and disease control, and the careful use of fertilizers. By combining these practices, turf managers can create a balanced system that supports robust turf growth while minimizing negative environmental impacts.
Soil Management
Effective soil management is fundamental to ITM. This involves regular soil testing to monitor pH levels, nutrient content, and soil organic matter build up (thatch). Based on the test results, a suitable programme of inputs and cultural practices can be incorporated to provide a healthy growing environment for the turf grass.
Water Management Techniques
Efficient water management is crucial for sustainable turf management. ITM promotes the use of effective irrigation systems that deliver water where and when it is needed, reducing over-watering and promoting deep root growth. Utilising soil moisture sensors, or handheld moisture meters can help optimize water use. Additionally, the use of wetting agents can significantly enhance water infiltration and distribution in the rootzone. Wetting agents reduce the surface tension of water, allowing it to penetrate hydrophobic soils more effectively, and can also be a crucial part in keeping the plant dry and reducing disease outbreaks.
Pest and Disease Control
Integrated pest management (IPM) is a key component of ITM. Managing all inputs to the surface and utilising modern monitoring techniques based around risk of disease outbreak, and early identification and targeting can significantly improve disease outbreaks. This approach emphasizes the minimum but appropriate use of chemical controls where they are registered for use.
Fertilizer Use
The careful use of fertilizers is essential in ITM. This involves selecting the right type of fertilizer and applying it at the correct rate and time to meet the turf’s nutritional needs without over-applying causing nutrient runoff or leaching or under-applying and leaving the plant weak and open to infection. Slow-release fertilizers, controlled-release fertilizers, and organic-based fertilizers are often preferred for their long-lasting effects and lower environmental impact. Conventional fertilisers will be necessary at times to elicit certain responses. A balanced approach is what is required.
ITM as a sustainable strategy
By adopting ITM, turf managers can achieve high-quality, resilient turf surfaces that are both aesthetically pleasing and more environmentally sustainable. This holistic approach not only enhances the health and appearance of the turf but also contributes to the long-term sustainability of turf management practices. As the industry continues to evolve, ITM stands out as a crucial strategy for achieving the dual goals of turf excellence and environmental stewardship.
