Answer
Composting is the natural process of converting organic waste (plant and animal materials) into nutrient-rich manure through microbial decomposition.
What is Compost? Compost is dark, crumbly, earthy-smelling material formed when organic waste decomposes. It's often called "black gold" by gardeners because of its high nutritional value for plants.
How Compost is Made - Traditional Method:
Step 1: Select Location
- Choose a shaded, dry area in your garden
- Dig a pit about 1-2 feet deep
Step 2: Add Organic Materials (Layers)
- Brown materials (carbon-rich): Dried leaves, straw, small twigs, sawdust
- Green materials (nitrogen-rich): Fresh grass, vegetable waste, fruit peels
- Alternate brown and green layers for best results
Step 3: Maintain Moisture
- Sprinkle water to keep the pile moist (like a wrung-out sponge)
- Not too wet (causes bad odor) or too dry (slows decomposition)
Step 4: Ensure Air Circulation
- Turn or mix the pile every 7-10 days using a stick or shovel
- This adds oxygen needed by decomposing microorganisms
Step 5: Monitor Temperature
- The pile will heat up (50-70°C) as microorganisms work
- This heat kills weed seeds and harmful pathogens
Step 6: Wait for Maturation
- Takes 2-3 months in warm weather
- 4-6 months in cooler climates
- Ready when material is dark, crumbly, and earthy-smelling
Materials to AVOID in Composting:
- Meat, fish, dairy products (attract pests)
- Diseased plants
- Pet waste
- Plastics, metals, glass
- Chemically treated wood
Benefits: Reduces waste, creates free fertilizer, improves soil health, retains moisture, and reduces need for chemical fertilizers.
