I have been reading around and asking about sharp sand and drainage.
That said, all sands improve drainage as they create channels or pores for the water to travel through. There are some fascinating, (and a lot of very dry ) books on the subject - mainly aimed at sports turf management.
That is a quote from a Soil Management student.
So Daituom have you read these books?
