Recomposted

Recomposted refers to organic material that has undergone a secondary composting process. In primary composting, raw organic matter is decomposed by microorganisms. Recomposting takes this partially or fully composted material and subjects it to another round of decomposition. This can occur intentionally or unintentionally.

Intentionally recomposting can be done to further stabilize the organic material, reduce pathogens, or improve its physical and chemical properties. This might involve turning the compost pile again, adding new organic matter, or adjusting moisture and aeration levels. The goal is to break down any remaining easily degradable compounds and create a more mature, humus-rich product. This mature compost is often preferred for horticultural applications as it is less likely to burn plant roots or contain weed seeds.

Unintentional recomposting can happen when composted material is stored for extended periods, particularly if it remains moist and aerated. Over time, further decomposition will naturally occur. The term can also be used to describe a situation where partially composted material is mistakenly added to a new composting batch, effectively beginning a recomposting process. The benefits of recomposting are similar to primary composting, but often at a more advanced stage of maturity and stability.
