IBS Rapid Composting
from On-farm composting methods by the Food and Agriculture Organization (FAO). 2003
The IBS (Institute of Biological Sciences) Rapid Composting method is also an example of the rapid composting method, with the additional use of compost fungus activator (CFA).
Materials:
• Trichoderma harzianum (CFA)
• substrates: rice straw, weeds, grasses, ipil-ipil leaves, legumes, chicken manure/Cow manure
• compost pen OR bamboo poles with holes
• plastic sheet/sack
Procedures:
1. Collect raw materials for the compost.
2. Reduce the size of the plant materials by using a shredder or by manual chopping.
3. Mix carbonaceous and nitrogenous substrates at a ratio of 4:1. Some possible combinations are:
3 parts rice straw to 1 part ipil-ipil;
 4 parts rice straw to 1 part chicken manure
 4 parts grasses to 1 part legumes to 1 part manure
4. Pile the substrates loosely in a compost pen that is raised 30 cm from the ground. OR pile the substrates and insert perforated bamboo poles horizontally and vertically.
5. Scatter the compost fungus activator or (CFA) on to the substrates during piling. Use 1% or more of the total weight of the substrates for faster decomposition. Mix thoroughly.
6. Cover with a plastic sheet or a plastic sack.
7. The compost heap will gain heat in 24-48 hours. Maintain the temperature at 500°C or higher.
8. Turn the pile every 5 – 7 days for the first two weeks, and thereafter once every two weeks.
9. The compost will be ready for harvest in 21 – 45 days. The compost should have an earthy smell, not a foul odor.
10. The raw materials should be unrecognizable and broken down to humus.
11. Harvest the compost and let it dry in the sun for 2 days.
12. Place in sacks and store in a shaded area.
