Use of composting manure helps in:
1. controlling the soil erosion
2. soil formation
3. water conservation
4. controlling Green House Gas Emissions
Choose the correct option from the codes given below:
The compost itself is beneficial for the land in many ways, including as a soil conditioner, a fertilizer, addition of vital humus or humic acids, and as a natural pesticide for soil. In ecosystems, compost is useful for erosion control, land and stream reclamation, wetland construction, and as landfill cover (see compost uses). Organic ingredients intended for composting canal ternatively be used to generate biogas through a naerobic digestion. Anaerobic digestion is fast overtaking composting in some parts of the world including central Europe as a primary means of down cycling waste organic matter.
- 1. Concentrates Nutrients
- Easier to transport
- Composting Kills Parasites
- Usable in organic systems.
- Usable on land where food is grown for direct human consumption
- Kills weed seeds
- No odor when spread
- Helps in soil formation by creating the humus in the top soil.
- Soil with organic matter holds not only water, but also the nutrients around plant roots, where they can be used efficiently. Thus it helps in water conservation also.
- Loses about half the available nitrogen
- Releases greenhouse gases
- Need to have a composting area
- Need to control rainfall runoff from the compo sting area
- Difficult to do with liquid manure
- Some manures might need a carbon source
