STEPS IN MAKING COMPOST (PIT METHOD)

The following are steps for preparing compost using pit method.

Dig four pits labeled A, B, C and D. of equal size (1m * 1m * 0.5m).

Arrange the materials for making compost in layer separated by soil in pit A (Loading pit) 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 ids now the COMPOST/MANURE after 6 -8 weeks.
