Methods of making compost
There are two methods of making composts; they are 1) Pit method and 2) Heap method.
Pit method:
- Dig four pits of different sizes.
- In the first pit(loading pit), arrange the materials for making compost in layers separated by soil and wet with water for easy decomposition.
- After two weeks, move the content of pit A to B (first turn).
- After about one week, move the content of B to C (second turn).
- After another one week, move the content of pit C to D.
- Cover the compost to prevent evaporation, leaching and erosion before applying it to the farm.
- The content in pit D is the COMPOST/MANURE.
Heap method:
Using this method, compost is prepared by placing the compost materials in a heap, it is made wet with water and then buried with soil.
