Good Worm Casts vs Good Compost. Worm Casts cost $400 a ton vs $30 a ton for Compost 1000 sf will use $4 of worm casts @ 20 lbs per 1000 or $4 of compost @ 266 lbs per 1000 (which is about 1/4 yard or 6.75 cu ft or about 1 heaping wheel barrow) Soooooo.......................... The question is which method is going to give the soil the most benefit? Let's use turf grass as an example. Kiril, Tim, Tree, Groh, ICT, Barry, dirt, Mudd, dusty, Natty, Small, compostwerks, folks who have done this - what say you? Questions to ponder. Same cost for each but lots more compost 266 lbs per vs 20 lbs of casts. Is this enough casts? Is it too much compost? I currently put down these rates of each and find more benefits with the compost - why is that? Especially when seeding and top dressing with the compost I get fuller thicker results faster and even long term. going to do some test plots this spring to see from bare dirt and from existing turf to see what happens - lets get some discussions moving on this topic!
