How Composting Works: A Scientific Guide

Composting is a natural process that turns organic waste into nutrient rich soil.
This process is driven by unseen microbes—including bacteria, actinomycetes, and fungi—that digest organic matter like fruit peels, leaves, and cardboard.
As these microbes metabolize organic material, фермерские продукты с доставкой they produce CO2, moisture, and thermal energy as metabolic outputs.
The heat generated can reach temperatures between 120 and 160 degrees Fahrenheit, which helps kill harmful pathogens and weed seeds.
For composting to work efficiently, four key elements must be balanced.
The first component consists of high-carbon "browns" like dry leaves and shredded paper.
These include dry leaves, straw, cardboard, and sawdust.
The second pillar is nitrogen-dense "greens" like vegetable scraps and fresh grass.
Examples include citrus rinds, spent tea leaves, lawn clippings, and fresh herb stems.
The ideal ratio is about 25 to 30 parts carbon to one part nitrogen.
An imbalance—whether too many browns or too many greens—can stall the process or create foul odors.
The third element is moisture.
Aim for the consistency of a well-squeezed kitchen sponge, not dripping wet or dusty dry.
Dry conditions cause beneficial microbes to go dormant, stalling decomposition.
If it is too wet, oxygen gets trapped and anaerobic bacteria take over, producing foul smells.
The fourth vital ingredient is air circulation.
Regularly fluffing or turning the compost ensures oxygen reaches the microbes that thrive in airy environments.
Not everything can be composted.
Fats, bones, cheese, and greasy leftovers lure rodents and decompose slowly.
Feces from cats and dogs, as well as moldy or infected garden plants, pose health risks.
Focus on non-animal, non-oily organic matter—fruit cores, tea leaves, and garden prunings—for clean, odor-free compost.
The time it takes to make compost varies.
If you aerate weekly and maintain ideal moisture and balance, you may harvest compost in 60–90 days.
Without intervention, it may take a year or more.
When fully mature, compost is velvety, dark, and has a clean, soil-like aroma.
Apply finished compost to flower beds, seedlings, or lawn top-dressings for lasting benefits.
Improving soil structure and helping plants absorb water and nutrients more effectively.
Diverting organic matter from landfills cuts methane and reduces your carbon footprint.
In anaerobic landfills, rotting food generates methane—25 times more harmful than CO2 over 100 years.
You close the loop—transforming scraps into fertile earth that nourishes new growth.
It is a simple, science based practice that anyone can start, regardless of space or experience.
No matter how small your space, composting roots you in the planet’s regenerative rhythms
