如何计算Compost
learn.whatIsHeading
Composting decomposes organic matter into nutrient-rich amendment. It reduces waste, enriches soil, and improves water retention.
分步指南
- 1Microbes decompose carbon and nitrogen, generating heat
- 2C:N ratio 25-30:1 optimal (greens 15-30:1, browns 100-200:1)
- 3Time to completion: 2-6 months warm climate, 6-12 months cool climate
例题解析
输入
Kitchen waste 100 kg/month, yard waste 200 kg/month mixed
结果
Compost ready ~4 months, reduces landfill 3.6 tonnes/year
Plus soil improvement
常见错误注意事项
- ✕Wrong C:N ratio (too much carbon = slow decomposition)
- ✕Insufficient moisture or aeration
常见问题
What shouldn't be composted?
Meat, dairy, oils (attract pests), diseased plants, perennial weeds. Avoid pet waste and invasive seeds.
Can you compost at scale?
Yes; municipal facilities handle tons. Home composting good for yards; large operations need specialized management.
