If it's brownish/black that's a good thing. It appears to be a gray color in that photo. Did you look at my composting thread? There's a lot of information in there that will help with getting started on c/n ratios of materials, exc.

Thanks Hyphaenation, that was a really interesting site, and they have a pretty quick turnaround on their compost based on a simple looking recipe.

One thing that I noticed at this site as well as in Lazlo's kickass premium composting post is that chicken manure looks like it can be added to the straw (with maybe a little bit of gypsum) to get a simple but enhanced compost, with correct C/N ratios. I have some composted chicken manure pellets sitting around, gonna grab a scale and crunch some numbers.

Will I lose a lot of the chicken manure nutrition from the compost when I'm pasteurizing it?

I was going to offer this recipe earlier, but didn't think you could get chicken manure. Or didn't want to fool with it. Anyways...........

2200 lbs. of wheat straw
1300 lbs. of chicken manure (broiler chickens)
130 lbs. of gypsum

Of course you'd want to hack the ratios down to however much compost you want to make.

thanks Lazlo. Your right, initially I didn't want "too many" ingredients, but it looks like having the correct ratio is pretty important.

The straw that has been broken down will still get a test run hopefully alongside regular straw to show any one interested whether it might be at all worth waiting an extra month for the straw to decompose a bit.

The jars that were prepared didn't look right, the rye berries were too soft and some were split, and the birdseed seemed too dry after a simmer and boil/soak, respectively. Another batch will be prepared and hopefully it won't be too long before the straw is being colonized.

For pasteurizing compost , you don't want to soak and drain like straw..Instead conserve the nutes by hydrating to optimum for mush growing , then stuff ziplocks with it and
heat in a huge pot, half full of water w a lid..

Alternately, u can place in covered pots/trays and bake in the oven..Use an oven thermometer to varify cook temp...This takes a bit longer but u can process more compost...

No doubt. You do not want to use a hot water bath for compost that leaches nutrition. It becomes a mold magnet once you do so. It completely unbalances the c/n ratio and drowns aerobic microorganisms that are needed to prevent contamination after the pasteurization process.
