straw/poo, and compost question

my question... in the growlog forum all the bulk substrate logs generally either take some form of manure, mix it with straw, or use either as the only ingredient and then pasteurize.... and its ready for spawning in paul stamet's the mushroom cultivator there is a whole chapter on composting, ((you mix raw materials, build a pile, and compost them over the course of a few weeks. then you pasteurize and condition the compost does anybody know the difference it makes? most people seem to do fine without composting their substrates, just mixing, pasteurizing, and spawning.

Well someone reasently did a grow log with composted manure. It seemed to work really well. The point is though, normal dung/straw substrates work just as well. I have yet to see a bad flush or shitty fruit from any of my bulk substrates. So if you have the time to compost you manure then by all means give it a go. Otherwise just try well dried and pastuerised dung/straw substrates.

Yes, it does seem kind of strange that Stamets has a whole chapter on composting and explains how proper pastuerizing is a process which takes many hours and requires strict temprature control. Yet there are kids here who say they pasteurized by putting in a microwave at high for 10 minutes....thats not pasteurizing!
I've used compost that was pasteurized and compost that was only sterilzed and had success with both. I know others have had success using straight manure either fresh or dried and reconstituted.
So whereas commercial mushroom farmers are concerned with yield and use every little scientific trick to produce more, we are stuck with inferior equipment and supplies and more or less wing it with whatever method we find is successful and success, to some degree, is pretty easy to obtain using one of the many methods which utilize manure.
Personally, I followed Stamets instructions, mixed a pile, turned it by hand until I got a pitchfork, that made it easier, now I have a nice pile of real compost and I'm finding it works very well.
Next, I'll try some straight horse manure and see how that compares.

The raccoon composts & loves it.
The advantage is that you can add more lignin, complex sugars (by adding vegatible & fruit refuse) & other diverse nutrients. The consistancy of compost is also nice. Plus it has little or no smell & often, a more diverse & better microbe count.
But, pasturized dung is the king of the woods & grows great large fruits in abundance. The raccoon often makes a substrate of 50/50 mix of his compost & straight dung.
If you have the room, temperement & time, a compost pile is a great & frugal investment. Nothing beats having a ton or 2 of available substrate on hand.
Save & wash egg shells. Crushed, they work like oyster shell, as a ph buffer.
The hurdle with using straight dung is: That most often beginners make it TO WET. Which can lead to rot, slow colonization & contam's setting in .
If you can find dry aged dung? Bake it dry to pasturize it. Then add preboiled water to hydrate it. If you can get it real moist, yet cannot hardly squeeze one drop out. It is about right.

Luckily my dung is supplemented before the race horse eat it SO it does tend to come out a very high quality. As far as smell or overly wet dung goes I`ve never experienced either. If you read enough and use your brain you should always succeed.

Yes, I found that the compost has very little odour and can be buffed up with things like seaweed, kelp and eggshells. But it is a project, kinda fun though. I really got off on the ammonia fumes when I was turning the pile.....
