I remember upsydaisium...
Re clay with sand added...
I trudged through a number of plantations (Louisiana), where the crew planted pines in a soil type known locally as "gumbo".
Was supposed to be really good stuff... But rough to plant in..
I useta maintain a garden (in middle ga), in some heavy clay... Property owner found a barn where the horse owner added sand to his horse poop...
Gotta say that from my experience... The poop with the sand added did not help that heavy clay at all...
Seemed like the heavy clay produced better before the sand was added...
Also seemed like the usual poop that has the wood shavings and/or sawdust added did a far better job at soil conditioning...
You go ahead and import sand, if that's your ambition, but... I'd try a two garden test where one didn't get the sand, and see what a side by side test produced over time.
