How to Accelerate Composting Cycles to 30 Days

Q1: How to Shorten Cycles to Under 30 Days?

  • Thermophilic Bacteria: Add high-temperature strains (Bacillus subtilis) to boost decomposition.

  • C/N Ratio Control: Maintain 25:1–30:1 (e.g., mix 3 parts straw with 1 part manure).

  • Frequent Turning: Use automated agitators every 2 days for oxygenation.

Q2: Do Coffee Grounds/Tea Leaves Affect Decomposition?

Yes—positively! They add nitrogen (ideal C/N ratio: 20:1) and improve porosity. Limit to ≤20% of total feedstock to avoid acidity.

Q3: Balancing Yard Waste and Food Scraps

  • Carbon Sources: Shred branches/leaves (C-rich) to 2–5 cm pieces.

  • Nitrogen Sources: Mix with fruit/vegetable scraps (N-rich) at 3:1 volume ratio.

  • Moisture Check: Adjust to 50–60% using a squeeze test (dripping = too wet).
