MEANING OF COMPOST / MANURE

Compost is a mixture of decaying vegetation and manure (animals and plants); used as a fertilizer.

Compost can be prepared on a small scale for home gardens, usually in a simple pile of yard waste and kitchen scraps, though compost bins and barrels are also used

Compost improves plants nutrients and makes the crop to grow well.

Compost is an organic fertilizer that can be made on the farm at very low cost. The most important input is the farmer’s labour. Compost is decomposed organic matter, such as crop residues and/or animal manure.

 

LOCATION OF THE COMPOST

We should consider the following before preparing compost

1. A source of water should be very near or close-by
2. The ground should be leveled and well drained.
3. Proximity to the farm garden is very important
4. It should be close to where materials for preparing compost will be collected.
5. There should be some shade to prevent harsh temperature from drying up the heap.
6. The compost should be stored in a cemented place or area with an overhead cover.

MATERIALS FOR MAKING COMPOST

1. Water
2. Soil
3. Plant garbage
4. Animal muck
5. Food waste
6. Little Wood ash (saw dust)
7. Dried flower
8. Dry leaves
9. Weed without seed

 

METHODS OF COMPOST MAKING

1. Pit method
2. Heap Method

STEPS IN MAKING COMPOST (PIT METHOD)

The following are steps for preparing compost using pit method.

1. Dig four pits labeled A, B, C and D. of equal size (1m * 1m * 0.5m).
2. Arrange the materials for making compost in layer separated by soil in pit A (Loading pit) and wet with water for easy decomposition.
3. After two weeks, move the content of pit A to B (first turn).
4. After about one week, move the content of B to C (second turn).
5. After another one week, move the content of pit C to D.
6. Cover the compost to prevent evaporation, leaching and erosion before applying it to the farm.
7. The content in pit is now the COMPOST/MANURE after 6 -8 weeks.

PREPARING COMPOST USING HEAP METHOD

Compost is prepared using heap method by placing the compost materials in a heap buried with soil and moistened with water.
