From the Greens Sustainable Golf Courses Maintenance of Golf of Golf Courses by Wg. Cdr. Arun Kumar Singh (Retd) President, GCS&MAI olf Courses evolved from the grasslands of Scotland and the game of golf has been broadly played on pasture land. The sprawling pasture lands populated with local species of grasses was kept trimmed by grazing livestock and other herbivores. They were a habitat for diverse fl ora and fauna which not only supported the environment but also was benefi cial communities. The boom in construction of modern golf courses, especially in the post war era, led to creation of large golf courses relying on moving lot of material and planting of single species of new variety of grasses. Over a period of time, the wheel has turned and renowned golf architects like Robert Trent Jones (Jr), Tom Doakes, Gil Hanse etc have shifted their focus to ‘ Low Impact’ design and construction. The old ways of Scotland are back in vogue and an attempt is being made to blend the golf courses into available natural habitat in the neighborhood. Efforts are being made to create facilities which are not only environmentally sustainable but also cater to fi nancial and social sustainability. Maintenance of golf courses needs to also follow the path of sustainability and need to adapt to the local realities. The creation of large modern golf courses focusing on grandeur did lead to adoption of cultural practices in golf courses which seem to have been largely similar to those prevalent in modern Agriculture. It is interesting to appreciate the changes in last 70 odd years in the fi eld of Agriculture (Agar = land and culture = cultivation i.e cultivation of land) and Agronomy (Knowledge of land). Developments in the fi eld of Science and Technology increased the yield from crops substantially but it also led to increased usage of chemicals such as pesticides and large earth moving machinery changed landscapes into fl at arable lands which destroyed the habitat for other living beings like fl ora and fauna including the soil microbes. The policymakers and the farming community used the increased yield to shift the paradigm to ‘Grain based Agriculture’ from the age old mix of pastures and agricultural land. Increased production of grains and the subsidies made it lucrative for being used as animal feed and food processing industry. Vast tracts of arable lands being used for producing grains have created an environmental imbalance and some even believe that it has caused a nutritional imbalance too. Feeding the ever increasing populations is a necessity and production of food with rising yields will be always looked upon as a virtue. The law makers cannot afford to alienate the powerful farmer lobbies across the world and the environmental damage caused by modern agriculture is likely to be overlooked. Golf on the other hand is perceived to be an elitist game which is further enhanced by long waiting lists and high cost of entry to golf clubs. Golf courses have to necessarily follow sound policies to remain sustainable especially from the ecological point of view. Indian Golf Courses have in the past 25 years been exposed to creation of modern golf courses with sand based ‘Greens’ with short or dwarf variety of grasses being planted on the fairways and greens. Increased TV coverage of golf tournaments and more golfers playing on better courses has led to increased expectations from the green keeping staff. Course managers not only have to adopt good practices but also need to disseminate more information to golfers playing on the course for wider acceptance and education. In the Indian context, maintenance practices must focus on some very vital areas to ensure that the golf courses continue to live and remain sustainable. These could be reduction in usage of sand, water, chemicals and creation of bio diversity. Water. We live in times of water crisis and doomsayers are already predicting ‘Water Wars’. Days of fl ood irrigation are over and golf courses must learn to invest in effi cient irrigation systems for creating better effi ciency. The course managers, at the same time should incorporate hand watering to cover areas where necessary to save water even further. Studies do reveal that most golf courses are actually over irrigated and using a simple soil moisture meter can be a great water saver. Reducing the closely mowed areas (Greens, Fairways and short rough) can not only reduce the consumption of water but can also reduce costs related to man hours / wear and tear of equipment. Consumption of water can also be reduced by selection of local species of grass wherever possible. Indian varieties of grasses have good drought tolerance and are resilient. Sand. It is a rapidly depleting source and the desired quality of sand is already diffi cult to fi nd. Obviously, using sand for top dressing for limited areas is desirable and so is to use the material plugged out in coring after breaking it down as top dressing material. Generally speaking the material used at the time of construction has undergone more quality checks and is superior to the material procured in subsequent years from new sources. Creating Bio Diversity. A typical 18- hole golf course may be spread over 100 acres but the playing area is only spread over 50 to 60 acres. Out of this 50 odd acres, the cultivable area can be further reduced by creating some bio diversity near the Tees (say around 100 yards) by having local grasses and may be even some other species of GolfPlus vegetation which require minimal care. Increased bio diversity will also help in creation of better habitat for soil microbes, birds, other species etc and will help the golf course. Requirement of using pesticides and other chemicals will also reduce considerably as an improved bird life will feed on the pests. Fertilizers. Available evidence suggests that most golf courses are fertilized aggressively and need to tone down the usage of fertilizers in non essential areas. A better application of fertilizers in target areas will also provide different colors and enhance the visible appeal of targeted areas. Similarly, usage of other chemicals (fungicides, pesticides etc) can be integrated and reduced. Playability. Maintenance practices should primarily focus on the playing conditions rather than the visual appeal. Firm and consistent surfaces are required to enhance playability and they are not dependent on color of turf. On the contrary heavily irrigated turf having shades of dark green color is often shallow, inconsistent and prone to compaction of soil. Sequestering of Carbon. Grass as a specie is almost completely comprised of Chlorophyll and the entire plant is engaged in photo synthesis which makes it an extremely effi cient plant for sequestering carbon. A growing blade of grass is most effi cient when it is mowed to a height representing its growth phase as it has a high rate of metabolism when it is in the middle of the ‘S’ curve. It is seen that pasture grasslands where the grass is kept clipped by the grazing herbivores (ruminants like cattle, sheep etc) are very effi cient in sequestering of carbon as the animals keep shifting to new grounds in search of the right height. This natural cycle of letting grass rest and grow before being clipped could be the practice which should be followed by golf courses to become effi cient contributors to the environment. The mowing of golf courses should incorporate some resting schedules for the grass for the best benefi ts. The cultivation practices in the golf courses must help in making them not only environmentally sustainable but also be socially and fi nancially sustainable. Reduction in usage of resources will certainly reduce costs and creating bio diversity while blending with local landscapes will make them socially more acceptable. Above all the golf course managers must disseminate information about the carbon sequestering benefi ts to a larger audience and also let players understand that playability of a golf course has little correlation with the color of turf!
