Heat Taking its Toll on Poorly Drained Turf

This is a picture of an area of our 17th fairway.  These brown areas are where water sits all the time and especially in June of this year where the rain was relentless.  Now that we have the heat and high humidity, these areas are stressed and thinning due to poor root systems and the heat makes them wilt easily and turn brown.  Of course it is a catch 22, if we over water them to prevent them from wilting, we will encounter other problems like fungus that will kill the areas all together.  It is best to lightly syringe to take the stress off and eventually it will grow out.  The best solution is to add drainage to this area so we stop the water from sitting for prolonged periods of time.  Also, we have a lot of localized dry spots on other fairways where the turf is brown and stressed since the soil is hydrophobic, meaning it cannot take up the water, it actually repels it.  Even though we are throwing a lot of water and using wetting agents, the problem has not subsided.  We will need to address thatch issues this fall to allow water to reach the root zones easier.  This is a tough stretch of weather where we are either facing stressed turf from all the wet June weather, fighting fungus off and now fighting localized dry spots.  To say the least this season is going to tax my pesticide and fertilizer budget, my labor budget and my sanity.
