Compost definition:
AEROBIC DECOMPOSITION of ORGANIC MATTER

Must stay Aerobic throughout the entire process. When anaerobic (low oxygen) conditions are present, a number of things happen:

• The beneficial fungi and bacteria go dormant and allow pathogens to takeover. 
• The nutrient cycling biology (flagellates, amoebae, nematodes, etc.) are killed or go dormant. 
• The soluble forms of nitrogen, sulfur, phosphorus are converted to gases and are lost.
• Strong acids are produced.
• Alcoholand preservatives are made.

How to tell if your pile has turned anaerobic

• IT WILL SMELL BAD, if it sticks, or has a foul odor of any kind. DO NOT USE this. Compost should always smell good.
• It looks black, and is now reduced waste, not compost
• It has a white chalky layer that has formed, this is actinobacteria, an anaerobic microbe.
• Smell your pile, smell the thermometer when you pull it out of the center, reach in as far as you can to the pile without burning yourself and pul some out and smell it, smell it when turning it. If at any point your pile becomes anaerobic, Start over.

There are several reasons why a compost pile may turn anaerobic. 

• It could be too wet or waterlogged. Spread out pile and allow to dry out a bit, then rebuild pile.
• It could have too much high nitrogen or greens. Causing pile to too hot or heat up too fast or both. If so, mix in more carbon/browns.
• The particle sizes may be too small and pile is not porous enough, making it too dense to allow air in etc. Add chunkier materials to the mix to allow air pockets and airflow.

High have a high diversity of microbiology so decomposition will continue through all environmental conditions.High diversity of organic marterial to grow high diversity of organisms Everything in pile MUST reach 131-165 degrees to kill pathogens, pests, seeds, etc.

Compost in batches
Most people have bins or piles that they continually add to over time. Thermal composting is a batch process, source materials should be kept in 3 seperate piles (Greens, browns & high nitrogen) and not allowed to become anaerobic until a proper pile is to be made. In a proper compost pile, human pathogens, plant pathogens, seeds, root feeding nematodes, and undesirable bacteria are killed off. This is achieved by ensuring every piece of organic material in your compost pile makes it to the center at some point during the composting process and achieves a the appropriate temperature range for the proper amount of time.  If the pile has been turned 4 to 5 times already and a handful of kitchen scraps or other material is added to the pile, new pathogens could be being added that will not make it to the center of the pile to be composted.

Begin making material piles of greens, browns and high nitrogen. Keep them separate and dry until a compost pile is to be started. 
If starting material piles become too wet or anaerobic, turn them. Check by smelling, bad smell means anaerobic
Pile must be at least 1 cubic yard in size. 
Use 10% High Nitrogen – 30% Greens – 60% Browns
High Nitrogen = seeds, manure, legumes, meat – 10:1 C:N Ratio
Greens = grass clippings, anything cut while it was green, kitchen scraps – 30:1 C:N Ratio
Browns – sticks, wood chips, branches, mulches 60+:1 – C:N Ratio
Soak brown materials overnight and greens if dry
Use the 10 bucket system, 1 bucket High Nitrogen, 3 buckets greens, 6 buckets browns 
More diverse the materials the better, should be a mixture of sizes to create air channels and pockets during first phase to avoid pile turning anaerobic to quickly. 
Homogenize/mix all materials together while placing into bin while spraying with water
Compost must be kept at 50% moisture
Check compost temp and moisture DAILY in middle of pile daily for first week, should reach 131 degrees in 3-5 days.
Smell pile for foul odors, bad smells are a sign of anaerobic conditions. Turn immediately!! 
To kill human pathogens, plant pathogens, and weed seeds, compost center must reach: 130-140 degrees for 3 days or 140-150 for 2 days or160-170 for 1 day 
Do not let pile exceed 170 degrees, 170+ is considered anaerobic and will breed pathogenic and disease causing organisms, it also starts creating alcohol. turn immediately!!
If compost is not heating up to 131+, either moisture level is off or there is not enough high nitrogen material or green. Turn pile and mix in water or more high nitrogen.
After pile center has reached between 130-165 for proper time, turn pile.
Center of the pile goes on the bottom, top goes in the middle, bottom goes on top. Add water as needed
Monitor pile temp and moisture again until center temp has reached 130-165 for appropriate time and turn same as above.
Pile must be turned between 3-5 times to ensure all materials have been heated to 130-165 for appropriate time.
Once final turn is completed, compost will take several weeks to cure. Keep moist.
Do not add anything to pile once compost has reach 130 degrees.
