not so green patches in my lawn

Hi, I have already posted my question almost three weeks ago in this news group. My problem is my lawn. I have put a new lawn last year on 6" topsoil. I have tried to take good care of my lawn (deep watering, fertilizing, good mowing). Up to fall last year, my lawn looked fairly good. After winter (in Alberta, Canada we are getting too much snow), my lawn has slowly started to utrn green except fey spots where i still cannot see green grass. These areas are not growing so I don't think it's a sign of fungus or bugs. As per suggestion i have got from my last posting, I gave my lawn a good deal of water. But still those not-green areas do not show sign of recovery. One thnk that I need to mention here is that I used winter fertilizer quite late in end of Oct. Looks like I shoudl have done it late Sept. I investigated the crown of my grass at different places. they all looked solid. It was suggested that if grass crown is soft, it might be a sign of dead grass. I used spring fertlizer a month ago. For the areas where the grass is green, I do have a lush grass. I had talk with my neighbour whose grass is very healthy and he does have quite bit of experinece in landscaping. he told me that the grass is fine, and I have to be patient and keep watering the grass and waiting for warm weather. I very much appreciate if you can let me know of your feedback.
thanks

Hi FardinA,
Possible fertilizer burn? Could the burned areas be where you made turn and applied too much? If the roots are brown then I'd say th grass is dead. Go ahead and remove the dead areas, scratch the soil add 1/4" of compost and reseed if you don't see any new growth i another 2 weeks.
