Steps in making compost (practical)

In making compost, the first step is to decide which of the type of compost we want to make.

The choice will be determined by certain factors. Example, if we want to choose the pit method we need to check if we have space and time to make five pits.

Then the second thing we do after deciding is to gather our materials, put them together then we start. If we have chosen the pit method below are the steps in making the compost.

The following steps are used in making a pit compost:

1. Select a suitable site for the compost pits. This site should not be near the classroom. A portion of the school farm is usually the best.
2. Clear the selected site by removing all weeds, grasses, and shrubs.
3. Mark out five pit areas with pegs and ropes.

Stages of making pit compost

1. The fifth pit, usually called the storage pit, should be bigger in size.
2. Dig out the soil in the marked areas to make the pits which should be 0.5 m deep
3. Erect a shed over the fifth or storage pit to prevent loss of nutrients by rainwater.
4. Collect materials, such as straw, grasses, leaves, ash, animal dung, urine, and water.
5. Put the materials into the first pit in this order: animal dung, ash, grasses, or weeds
6. Sprinkle them with urine and water. These form the first layer. Repeat the process until the pit is fully loaded.
7. Turn the materials into the second pit after 2-3 weeks and refill the first pit. The process is repeated every 2-3 weeks until the compost reaches the storage pit and is ready for use. At this stage, all the pits have materials at different stages of decay.
