Composting is a natural process that turns organic waste into nutrient rich soil.

It relies on microorganisms like bacteria and fungi to break down materials such as food scraps, yard trimmings, and paper.

The living components of compost derive energy from decomposition, excreting heat, vapor, and carbon dioxide in the process.

Temperatures in an active pile frequently hit the 120–160°F range, shutting down pathogens and preventing invasive seeds from germinating.

Success in composting hinges on managing four essential factors.

Browns—carbon-heavy substances such as cardboard, sawdust, and straw—form the structural backbone of the pile.

You can use options like torn newspaper, фермерские продукты с доставкой pine needles, or untreated wood chips as carbon sources.

The second is nitrogen rich materials, or greens.

Such as fruit and vegetable peels, coffee grounds, and grass clippings.

A successful pile typically maintains a C:N ratio between 25:1 and 30:1 for efficient breakdown.

Excess carbon starves microbes of energy, whereas surplus nitrogen leads to ammonia smells and nutrient loss.

Maintaining proper hydration is the third pillar of effective composting.

It should be moist to the touch—similar to a wrung-out sponge.

When moisture is low, microbial life slows to a halt.

Excess water suffocates aerobic microbes, allowing odor-causing anaerobes to dominate.

The fourth element is oxygen.

Frequent aeration replenishes oxygen, fueling the aerobic bacteria that drive rapid decomposition.

Certain items should never go into your compost bin.

Meat, dairy, and oily foods attract pests and take longer to break down.

Never compost pet droppings or plants infected with fungi or viruses—they can contaminate your soil.

For optimal safety and efficiency, compost only plant-derived materials like vegetable peels and leaves.

How quickly you get finished compost depends on your technique and conditions.

Frequent turning, correct C:N ratio, and consistent moisture can yield usable compost in under 90 days.

Passive composting—no turning, no monitoring—can stretch the process to over a year.

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.

It fosters better drainage, increases microbial activity, and amplifies nutrient uptake by plant roots.

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.

By composting at home, you contribute to a circular system where waste becomes a resource.

It is a simple, science based practice that anyone can start, regardless of space or experience.
