Comments through July 7 am

We would REALLY appreciate a "care and feeding" manual for Bahiagrass from the results of this survey, it would put to rest some internal bickering within our association. Thanks for conducting this study.
==================
I find that Argentine Bahia produces siginificantly fewer seed stalks than Pensicola Bahia once the sod is grown into a tight turff. Because stalks are considered detrimental to aircraft finishes use of Argentine is more satisfactory. It allows for reletively less frequent mowing during parts of the year when Pensicola produces more stalk than grass.
==================
For the past 26 years of operation I can say that I keep a well Maintained runway. The mowing is in response to wet or dry conditions allowing for grass growth. This year, and may be it's due to Hurricane charley, I have a real problem with the grass yellowing down the middle. It appears to be from mole-crickets but I'm not sure this time. My full runway length is 2800ft X 100ft wide useable for landing, with a 20ft easement on one side and a 30ft easement on the other side. This is a good thing your doing. Maybe the private airport owners of grass strips can find some info on maintaining their grass. If you know of an inexpensive was to get rid of mole-crickets please let me know. Good luck on your research.
===================
The runway was seeded with bermuda grass several times. The thing that helped the Bermuda grow the best was adjusting the PH with lime. The runway needs more lime but it has been very dry and applying lime will not be effective till it rains more. The runway is now 20-25% bermuda grass and 75% weeds and fescue grass but the weeds hold the soil and they grow well. I have tried to get rid of the fescue grass and sage grass because it clumps. I am glad that anything grows this summer due to the extreme dry conditions.
