Why So Much Compost?
I've read and cited the basic rule of thumb of 1 cu yard of compost per 1000 sq ft. But, I've never added that much compost at one time to my lawn. The last bag of compost I used, and actually read the application rate, the directions were 40#/500 sq ft.
I have mixed bagged compost with grains and spread over the lawn. I can't imagine spreading a cu yd/1000 of compost as a topdressing on growing grass. Maybe for a complete renovation.
Where did the 1yd/1000 rule come from?
What is the basis? Amount to increase OM a certain percentage or something like micro organism count.
Does anyone else think a cubic yard per 1000 sq ft is a bit much?
