Background: I am wanting to put sod on an area of our yard that had been covered in river rock (with black plastic underneath). I have removed the river rock and plastic, but it turns out the soil underneath it is clayey (2 in, when doing the 'ribbon test'), so I need to amend the soil. I got a soil sample taken (see attached), and it provided information about proper fertilizer for seeding/sodding, but since then I have decided I should try to amend the soil with some black dirt and compost mixture before doing the sodding (perhaps getting compost from Carver County Environmental or using alpaca or llama poo, or some combination of the above). Question 1: What do you recommend for amending the clay soil? Question 2: Once I amend it, is the attached soil sample along with its recommendations no longer relevant? In the meantime, do you have any suggestions/recommendations for fertilizer? (I may not have time to get another legit soil sample before I need to sod.) Thanks for your help! Ed B
