I bought an ecolawn 200 this spring. I use mainly bagged pelletized leaf compost in it. Nice and dry. 60 lbs per m. Called Easy-Flo.
To use bulk it has to be REALLY DRY our city makes really nice compost for $10 a yard, problem is they keep it outside untarped. I have nowhere to store it that's dry. I am looking into a cheaper bagged product around $10 a 50lb bag, and the rate is 25 lbs per m.
But small axe will probably find some bullshit reason for not topdressing since its after all ORGANIC.
