The weeds that appear in the seams of sod have little to do with any weed(s) growing in the sub-surface of the sod. Anytime there is an area where the turf is thin, be it due to injury, poor management practices, i.e. close mowing…etc, a weed seed will have access to light – the key ingredient for germination. I know this flies in the face of what another poster has suggested, but when you look at the turf, how many weeds do you actually see in the middle of a patch of sod. Few? Any? None?
As for the identification of your weeds, it is too difficult to name given your description. Other described characteristics such as vernation, leaf, sheath, ligules …etc, would aid in pinpointing what weeds are present in your turf. That said, the identification of the weed is unimportant unless you are considering pre-emergent or post-emergent chemical controls, and timing becomes an issue. Further, regardless whether the weeds are annual and will die, they can become very problematic, as many annuals are prolific seeders. Whatever control (cultural practices or chemical) you use, eliminating the weeds will reduce the likelihood of the cycle repeating itself.
