If the texture is right & there's no rocks, I suppose you could mix it in. I'd probably just store it to fill the eminent low spots you'll have after resodding.

Thanks reeljake.

I realize you have already purchased the soil, but are you sure you need it? If your drainage has been designed and cut into your lot by professionals, then adding more topsoil will change the drainage the wrong way. The worst case is you build up a little barrier that allows heavy rain water to back up into your basement.

Almost every soil can be improved and even perfected with a few tests and the occasional use of organic fertilizer. If you want to cancel the soil delivery we can help you through the process to improve your soil.

Manure should never be an ingredient to soil or anywhere in your garden. If you have access to some, be sure to compost it before using it. Once it is composted and smells wonderful, then it's called compost and no longer called manure.

Having said all that, I sense that you're going ahead with the new topsoil. In that case, go ahead and mix all the soils together. It will stink for longer than you expect it to, and the neighbors will all look at you funny, but it should not harm the new grass.

In the future if you want to use organics, it is a lot more cost effective to use anything except compost and/or manure. Even commercially branded organic fertilizers are considerably less expensive than compost. I use alfalfa pellets (rabbit chow) and corn meal. Other people use soybean meal, cottonseed meal, and Milorganite. The general application rate is 15-20 pounds per 1,000 square feet (10 kilos per 100 square meters).

We'll there you go, if DC says don't use the manure dirt, I would certainly defer to his experience on that. Not much manure around me in southern suburbia!

how are the laws in BC regarding pesticides for cosmetic use? I thought that several years ago a new law was established to prohibit the use of pesticides in even private properties.

You don't want to use unfinished manure, but if it is finished I think it is a better option than soil, since you don't know what's in the soil. Most soil sold to homeowners and landscapers are from construction sites, which means it usually comes with many things like plastic, glass, paint and weeds. You can't go wrong with compost if it is finished, since it will be clean from weeds.

If you have soil and compost you can definitely mix them together.

Happy Spring!
