The microbes hard at work in your compost pile require just the right amount of water. Too much means organic waste won’t decompose, too little and you’ll kill the bacteria. Compost should feel moist, but not soaking wet — like a wrung out sponge.
Composting works best with 40-60% moisture content. More on monitoring compost moisture here.
Everyone needs to breathe, even tiny microorganisms, so make sure enough oxygen is getting into your pile by turning your compost often.
Use a compost aerator or pitchfork to mix your pile. If you are using a compost tumbler, you’ve got it easy. Just crank that lever.
If you are using easily compacted materials (such as ashes or sawdust) mix in coarser materials first. People who build large piles often add tree branches or even ventilation tubes vertically into different parts of the pile to be shaken occasionally, to maximize air circulation.
Tip: A compost aerator makes it easy to turn the pile. Just jab the pointed end into the mix. As the aerator is withdrawn the hinged paddles open out, aerating and mixing the contents — without heavy lifting!
iv. Carbon to Nitrogen Ratio
For perfect compost, maintain a C:N ratio of 25 to 30 parts carbon to 1 part nitrogen, or 25-30:1. If the C:N ratio is too high (not enough nitrogen) decomposition will slow down. If the C:N ratio is too low (not enough carbon) you’ll end up with a smelly pile.
In general things that are brown (dried leaves, newspaper, straw) are higher in carbon than things that are green (vegetable scraps, garden waste, grass clippings).
5.) Mix rich, earthy compost into garden soil, or pile on top of the soil as mulch.
