Three Lessons From a Compost Pit That Did Not Work

One of the households we worked with early in our sustainable living programme set up a compost pit exactly as instructed, added kitchen waste diligently for weeks, and ended up with a smelly, waterlogged mess instead of usable compost. It was a useful failure, because it taught us more than most of our successful examples did.

The first problem was too much wet waste and not enough dry material. Kitchen scraps alone, without a regular addition of dry leaves, paper or garden trimmings, turn into a soggy mass that rots rather than composts, producing exactly the smell that puts people off the whole idea.

The second problem was poor drainage. The pit had been dug in a low corner of the compound where rainwater naturally collected, which kept the pile permanently waterlogged and starved it of the oxygen composting bacteria actually need to work.

The third problem was neglect of turning. Compost needs occasional mixing to bring oxygen back into the pile and speed decomposition evenly. Left untouched, the bottom rots anaerobically while the top barely breaks down at all.

We now teach a simple two-to-one ratio of dry to wet material, insist on a well-drained site or a raised bin instead of a pit in low ground, and recommend turning the pile roughly every two weeks. Every household we have supported since has had a noticeably easier time, and this failed pit is still the example we use to explain why each step matters.
