Largest Variety of Organic Compost

Chicken, Cow, Mushroom, Greenwaste


Oxygen Stage
When the windrow is formed microorganisms consume oxygen (aerobic decomposition.) As oxygen is used up aerobic decomposition slows down. Aeration is provided by mechanical turning to add oxygen and replenish pore space within the settled medium.This promotes air movement through the windrow.


Temperature Stage
Temperature increases due to microbial activity in the windrow.  The temperature increases to 40-60  C and generally is maintained for several weeks. As aerobic decomposition slows the temperature drops off.


Curing Stage
When the aerobic decomposition has slowed the curing phase has begun.  Oxygen usage is so slow the windrows don't need to be turned anymore. As the temperature drops to that of ambient air the compost is done.
