Hi - My town is installing a new soccer field. I have a few questions about the process so far and questions about the appropriateness of completing the work during the cold and snow. So far in this project, the contractor has 'turned' the old and weedy grass/soil to a depth of about 4". Nothing was removed. No herbicide was applied. The field then sat for a couple of weeks and was 'turned' again. Now this original 'organic material' (the dirt/grass/weed mixture) will be 'amended' with a 'calcified clay', the field will be 'laser graded', 'rolled' and then the large rolls of 2" thick special athletic turf will be laid. My questions are: 1) Does this site preparation and process sound right? 2) Won't the weeds just come back through the new sod? 3) The soccer field getting the new sod is adjacent to other athletic fields which won't get new sod. Without removing any soil or old grass, won't essentially adding 2" of new soil over this just create a different height field where transitions might be a problem? 4) Is the calcified clay amendment the only thing that should be added to the original soil? Will this product help with drainage or water absorption? Could another product do more to help with a wet field? 5) Is it too cold and snowy (we live near Chicago, IL) to lay the new sod? (It's not really expected to get above freezing for the next 10 days and there should be snow on the ground by tomorrow night.) Will the grass grow well come spring time if it is installed now? Come spring time, how long do we need to stay off of it so it can start to grow? Thanks for any help!!
