2. Basics of Composting


Before we explore the list of items you can use to make your own compost, let’s understand the basics of composting. Composting, at its core, is a natural process that transforms organic matter into a nutrient-rich soil conditioner. Composting is the controlled decomposition of organic materials through the activity of microorganisms, turning kitchen and garden waste into a valuable soil amendment.



3. The Process of Composting


Composting is a cyclical process that involves several stages, each playing a crucial role in the decomposition and creation of compost.


● Stage 1 -Collection : Gather a mix of green (nitrogen-rich) and brown (carbon-rich) materials. This can include kitchen scraps, yard waste, and more.


● Stage 2 - Piling : Layer the materials to optimize the carbon-to-nitrogen ratio, which is essential for microbial activity.


● Stage 3 - Decomposition : Microorganisms break down the organic matter, generating heat and causing the pile to decompose.


● Stage 4 - Curing : Allow the compost to cure or mature, ensuring the breakdown process is complete and the compost is stable.
